Pets in cars: interview with driving instructor Evan Giles

Driving instructor Evan Giles, quite possibly the most patient man in the Universe next to the Dalai Lama, with his cat Mozzie. Mozzie ain't so sure about a trip in the car!
SAT interviewed, in our opinion, the best driving instructor on the planet, possibly the solar system. He taught yours truly to drive, he’s teaching my cousin to drive, and he has patience in spades. Anyone who trusts an inexperienced driver with their life as they lurch around in a tonne of metal in Sydney traffic is remarkable. But to do it with humour and compassion? That's a gift.

What do you do for a crust?

I have been a driving instructor for 14 years and before that was a taxi driver and wheelchair taxi driver.

[Evan is too modest to mention that he runs Bamster Driving School, which you can visit at www.bamster.com.au]

What are the potential hazards of driving with a companion animal in the vehicle?

There seem to be 2 big issues: Distraction and inertia.

If an animal by its natural behaviour, or fear of being in the car, causes the driver to be distracted then we have a problem. A small animal scurrying, flying or jumping around will have the same effect as playing with a mobile phone or GPS: forcing the driver’s attention away from the road. Even if the animal is properly secured in a pet carrier the owner must not let the animal’s yowls and distress affect his or her driving. Put the carrier in the back seat perhaps?

In the event of firm braking or turning, or in a crash, any loose objects in your car will become deadly missiles. The heavier the object the more deadly it will be. In the case of animals that means deadly to both you and the animal.

In the case of utes, inertia and natural dog behaviour can lead to dogs being thrown off the vehicle. In one case involving some friends a dog fell over the side and was dragged on its leash for some distance, resulting in severe foot and leg injuries.

[Ed. I have seen numerous injuries and I am going to let you all in on a disgusting inside secret: in the veterinary emergency room, the characteristic foot injuries produced are known as street pizzas. They can take months to heal and are easily prevented].

What precautions can we take to ensure the safety of or non-human passengers?

All animals need to be properly secured. A pet carrier needs to be secured by a seatbelt. An animal not in a carrier needs a proper harness. If it is only secured by a leash then there is a risk that the leash will break, or if not then the animal will be severely injured if thrown around the car. Even if the animal seems distressed your first priority must be road safety. A similar problem applies when you are driving young children.

You have taught thousands of people to drive including myself. What are your thoughts about this student?


Porter is performing well for a first lesson, although I think he may have trouble with clutch control so should stick to automatic. I would like him to show a little more accelerator confidence so as to be able to match normal traffic speeds. An occasional mirror check would be nice. Also he seems to be very distracted by pretty girls on the side of the road. The instructor sounds a lot like me!

Can you tell us about any non-human companions in your life right now?

Mozzie looking adorable.
“Mozzie” (short for “Mozart”, named after T’choupi’s pet in the children’s TV series) is our cat. He could have been called “Micra”. He was a stray kitten when sighted under my Nissan Micra driving school car. In order to escape us he climbed up into the engine bay and was rescued via my opening of the bonnet. With a little help from Anne he has never looked back.

How does Mozzie behave in the car?

I have met cats who would jump into a car to explore or say hello. Mozzie is not that relaxed. I have also met cats who yowled pitifully for the entire drive. Mozzie is closer to that but I guess he could be worse.


A decent cat carrier is mandatory for safe cat transport.
 Any general driving tips for veterinarians or budding veterinarians?

Don’t drive impatiently! Your patients need you.

If you drive without patience then your patients might be without their vet.

Interview with Dr Lila Miller on shelter medicine and getting to zero

Dr Miller examines a young patient.
Dr Lila Miller is best known internationally as co-author of Shelter Medicine For Veterinarians and Staff (you can check out the second edition and download an exerpt from Wiley here) and more recently Infectious Disease Management in Animal Shelters (order a copy or download exerpts from here). She was also the first African American woman to graduate from Cornell's veterinary program and has witnessed massive diversification of the profession.

Dr Miller has more than 30 year experience working in animal shelters for the ASPCA and is Vice President of the organisation's Veterinary Outreach. She taught the first course in shelter medicine in the US, co-founded the Association of Shelter Veterinarians and has recieved a swag of awards in what many consider the toughest field in vet-land.

One of the most fascinating things about Dr Miller is that she almost quit vetting. She spoke candidly with SAT on the eve of her visit to Australia this month to speak at the 5th National Getting to Zero Summit (you can register here - the program looks amazing and its running next week, 10-14 September). 

[NB Dr Miller was apologetic that she writes "like she talks - a lot"...but I think you will agree that this interview needs to be run in full].

Tell us about yourself.

I have a bachelor’s degree in animal science and a veterinary degree. I grew up in Harlem, New York, where I still reside. My father worked in a clothing store as a tailor and pressing clothes and my mother sold tokens in the subway. I went to Cornell University as an undergraduate majoring in animal science and then went onto the veterinary school, where I graduated in 1977. To give you an idea of the times, I was the first African American woman to graduate from Cornell’s veterinary college, and was a member of the first class to admit more than just a handful of women! (How things have changed!) 

At the urging of my mentor,   Dr.  Joseph Tait, who was providing veterinary oversight of the shelter system in New York, I went to work at the ASPCA right after graduation to help the organization develop a health care program for the shelter animals. The ASPCA had the contract for animal control for New York City, operating 5 shelters that were open 24 hours a day, 7 days a week. The vast majority of the animals were euthanized by lethal injection or decompression chamber.

After helping convert to all euthanasia by injection, setting up health care and spay neuter protocols and helping implement adoption criteria, working both hands on and supervising the program for about 5 years, I became director of a clinic that provided low cost veterinary care to the community as well as the shelter animals. The clinic underwent several physical and staff expansions to meet the demand, but after 15 years, when the ASPCA finally decided that operating a municipal animal control program did not fit the mission of a national animal welfare organization, the clinic was closed by the agency that took over animal control. 

I then went on to teach shelter medicine at Cornell and write about what I had learned about caring for shelter animals. I then became director, senior director and vice president of the ASPCA’s Veterinary Outreach department, which had a staff of 3 other veterinarians dedicated to teaching shelter medicine to veterinary and shelter professionals, providing consultations and grants to shelters to help improve the lives of shelter animals, decrease euthanasia and increase the live release rate. My current job is vice president of shelter medicine, where I continue to focus on teaching and training veterinary and shelter professionals about shelter medicine. I also lecture extensively to veterinarians about their role in handling animal abuse, whether through education or participating in investigations and prosecutions.

In addition to co-editing the three shelter medicine textbooks, I co-founded the Association of Shelter Veterinarians and have been actively involved in veterinary regulatory medicine. I was a member of the New York State board that regulates veterinary medicine and on the National Board of Veterinary Medical Examiners that creates veterinary examinations for licensing boards.

What motivated you to become a veterinarian?

I always wanted to be a veterinarian from the age of about 5. I don’t recall what my initial motivation was, but as I got older I never wavered from it. I liked animals but wasn’t overly involved with them-I had a dog, parakeet and hamster over the years as a young child-and as I got older I found I liked biology so it seemed like a good match. All my education through high school was focused on attaining that goal.

Shelter medicine is a tough area to work in. What attracted you to this area and what sustains you in it?

I was never “attracted “to shelter medicine. It didn’t exist when I was in veterinary school or even after I graduated. As a student, I disliked visiting the shelter with Dr. Tait, thinking it was a depressing place and that I would never work there. But Cornell was very grueling and when I graduated I was drained and didn’t feel qualified to go into private practice and didn’t want to undergo the rigors of an internship either.  In fact, I wasn’t even sure I wanted to be a veterinarian any more. 


Adult dogs with parvovirus, a common affliction in unvaccinated populations.
When Dr. Tait  asked me to work at the shelter  and help him improve conditions for the animals I hesitated but thought it would be a good place to get hands on experience with animals for a couple of years without the pressure of private practice.  I also saw it as an opportunity to make a big difference in the lives of hundreds of homeless animals who didn’t seem to get much attention from veterinarians, and realized the impact of any improvements I could make would be far greater than I could make for the individual animals I would treat in private practice. 

I thought I’d stay at the ASPCA just long enough to help set up a program and train staff. After about 5 years, when the program was established and running well, I was asked to run a clinic in an underserved area of New York as well as continue to oversee the shelter program.  I saw another opportunity to help animals who would otherwise be neglected because their owners could not afford the cost of care. When the clinic closed, I was offered the opportunity to help teach others what I had learned over the years and it was another chance to make a difference. So what started out as a short term commitment borne of uncertainty about my future turned out to be my life’s work.

How have shelters changed since you graduated?

Shelters have changed dramatically over the last 30 years. When I started working in New York City, animals were essentially warehoused and most were killed after being held for a few days, sometimes only 48 hours.  All animals were admitted to the shelter regardless of their medical condition or conditions in the shelter, often leading to overcrowded conditions and some long term stays that sometimes lasted for months for legal and cruelty cases. The influx of animals far exceeded the adoption and return to owner rate. The focus was on animal control and nuisance complaints, not animal welfare.  But as the human animal bond increased and more was and is being learned about animal behavior and emotions, the focus has been shifting to rejecting euthanasia as the primary method of animal control.

Other ways shelters have changed?

Providing for quality of life, reducing euthanasia and increasing the live release rate have become an increasingly important goal for shelters. In addition to paying more attention to the physical health and behavioral needs of shelter animals, shelters are engaging the community in the struggle to end euthanasia of healthy but unwanted pets. Foster care, rescue groups and volunteer programs are much more common than 30 years ago.

Shelter staff are becoming more professional, receiving training in animal behavior and handling, and research is being conducted to debunk the myths surrounding adoptions and determine the best ways to get more animals into loving, long lasting homes. Research is showing that fee waived adoptions, adoptions as gifts and during holidays can result in good, long lasting placements. Behavior assessments are being used to match an animal’s behavior  to the lifestyle of potential adopters, and to make their stay in the shelter while awaiting adoption less stressful.

Early age desexing and high quality,  high volume sterilization techniques and protocols were pioneered by shelter veterinarians in an effort to decrease the births of unwanted litters that were finding their way into the shelters, swelling population numbers and making the job so much more difficult.  

Early-age desexing is a safe and effective means of controlling the number of unwanted animals.
Shelters are being retrofitted and designed with the welfare of the animal in mind, and as inviting, cheerful destinations for the family to visit to acquire a pet.

Shelters are also seeking alternative and more innovative ways to deal with free roaming cats, instead of the traditional method of just trapping and/or killing them.

Shelters are also starting to work together collaboratively, transporting animals at risk of euthanasia to areas of the country where they can be rehomed due to shortages. In some communities, shelters with greater resources are working with shelters with lesser means to save the lives of adoptable animals who would otherwise be euthanized because of minor health problems or overcrowding.

How do you think shelters need to improve?

One of the biggest areas we need to work on is the management of cats. The number of free roaming cats is unknown but estimates are over 50 million in the US alone.  Bringing healthy cats into the shelter ends up often being a death trap for them-so much so that some shelter professionals are recommending not bringing them to the shelter at all, and redesigning cat housing to meet their needs when they must be brought in. We need to improve getting the message out to the public about desexing, humane care and responsible pet ownership. We also need to improve customer service and outreach.

Shelter cats need our help!
You’ve written extensively about infectious disease control in shelters. Why is the shelter context different?

Disease control in shelters is problematic for a number of reasons. Shelters are often underfunded, understaffed and overcrowded, which creates a perfect storm for disease transmission. 

This puppy is suffering from parvovirus. Affected dogs are extremely flat and depressed, and display gastrointestinal signs including vomiting and haemorrhagic diarrhoea. It is treatable but requires intensive care.
Animals are admitted from varying sources with all types of disease exposure that the shelter has no history about. Mandatory holding of animals who may appear healthy but are incubating disease results in disease spread. Shelters are inherently stressful, which contributes to disease transmission. Many shelters were not originally designed to house animals so poor ventilation and porous housing materials that are difficult to disinfect may be used, contributing to disease spread. Many shelters are unable to provide ongoing staff training and the very sanitation protocols designed to prevent disease spread may inadvertently contribute to it. When disease does occur, many shelters cannot afford diagnostic testing and don’t have proper isolation and quarantine facilities for appropriate management. The list could go on and on as to why it is more difficult to control disease in shelters. 

Can you tell us about any non-human companions you share your life with?

I have a 10 year old tortoise shell cat named Miss Coco. I found her as a stray outside my building when she was about 6 months of age.  I had planned to turn her into the shelter, but she was very friendly and insisted on rubbing and endearing herself to me and my mother, who insisted on keeping her.  As my mother can no longer care for her she has been living with me for about 6 years now.

Burnout and carer’s fatigue are commonly associated with many areas in veterinary medicine, including shelter work. What are your strategies for dealing with these?

I don’t really have any strategy for dealing with burn out. I have certainly experienced it over the last 35 years but when I ask myself what else I could be doing that would have the same impact, I draw a blank and feel renewed.

Do you have any favourite resources that you can share on shelter medicine?

My favorite resources are www.aspcapro.org, www.shelter medicine.com, the shelter medicine and forensics on- line courses offered by U of Florida’s shelter medicine program, Maddies fund webinars, Humane Society of the US (HSUS) Animal Sheltering magazine and  the shelter medicine textbooks I edited with Stephen Zawistowski and Kate Hurley. The Veterinary Information Network (VIN) has a shelter medicine page, but the membership fee is expensive. Of course, one to the best resources is the Association  of Shelter Veterinarians (ASV) member’s list serve.

Any tips for veterinary students or veterinarians seeking to work in shelter medicine?

Veterinary professionals who wish to work in shelter medicine should try to familiarize themselves with the resources that are available and join ASV. The practice of veterinary medicine in a shelter is very different from typical private practice. Failure to understand the differences often results in unsatisfactory interactions between veterinarians and shelters. Students should select a veterinary college with shelter medicine training available-there are several in the US- join the student chapter of ASV and try to do a supervised externship program at a shelter.

What does “getting to zero” mean to you?


To me “Getting to zero” would mean society had finally met its obligations to the animals it domesticated and no more healthy adoptable animals would be euthanized for lack of a home.

Four things I learned: atopic dermatitis in dogs and cats

In cases of severe atopic dermatitis, body suits may be required to prevent self trauma. This particular image depicts Percy, looking incredibly handsome in an 00 size child's spencer, which was the perfect fit. 

Last night the ASAVA hosted another excellent webinar featuring veterinary dermatologist LindaVogelnest. Dr Vogelnest consults at the Small Animal Specialist Hospital (SASH) in Sydney. She was talking about atopic dermatitis.
According to the current definition (settled by a panel in 2002), atopic dermatitis is a pruritic skin disease with characteristic clinical features and is most commonly but not always associated with IgE antibodies to environmental allergens. Next to flea allergy dermatitis it is the most common allergic skin condition I see in canine patients, and it occurs in around 8-18 per cent of dogs and cats worldwide.

Affected animals likely have immunological dysfunction which is T cell driven, as well as skin barrier dysfunction leading to increased transepidermal water loss and increased penetration of pathogens, allergens and irritants. Signs include recurrent or relapsing pruritis which may or may not be seasonal, may or may not be steroid responsive (but usually is) and in dogs at least tends to occur around the face, ears, feet, ventrum and perianal region. Some dogs have recurrent anal sacculitis and/or recurrent secondary bacterial pyoderma and malassezia (yeast) overgrowth. Onset is usually between 1-3 years of age, but 95 per cent occur before the age of 5.
  1. Interestingly, atopy accounts for 21 per cent of skin and ear disease seen in general practice and is responsible for 15 per cent of total pet insurance claims in Australia.
  2. Dr Vogelnest manages acute flare with treatment of active infections where present; soothing shampoos; anti-inflammatory (0.5mg/kg) doses of glucocorticoids and limiting self-trauma (by use of body suits or Elizabethan collars).
  3. For long term control where possible she will use antihistamines (although stresses these are not highly effective as they only target one inflammatory mediator from mast cells, notably histamines); fatty acids (eg fish or evening primrose oil at 50-100mg/kg SID; or cold-pressed sunflower or safflower oil at 2mls/kg SID) and shampoos (she will step these up to daily in acute flare-ups and recommends a 10-15 minute soak). She is also a fan of moisturisers.
  4. Where stronger anti-inflammatories are needed she uses more potent topical steroid creams such as Elacaon, Aristocort or Cortavance; glucocorticoids (if long term she uses a dose of 0.1-0.2mg/kg in dogs and double that in cats) or cyclosporine at 5-7mg/kg.

Atopic dermatitis is multifactorial but there is certainly a genetic predisposition. Breeds that are over-represented include labs, staffies, Westies, JRTs, Scotties, boxers, bulldogs, ridgies, shar peis, bichons, beagles, great Danes, pugs and schnauzers. And in cat land, Abbysinians are especially prone.
It was a comprehensive, logical presentation – timely as this is the time that veterinarians in Sydney see a lot of itchy dogs (it is also the time of year when flea eggs are hatching like there’s no tomorrow). And a good reminder that these cases require a multifactorial approach. I liked the way Dr Vogelnest talks about management of acute flare-ups as well as long-term management. Owners typically request veterinary attention during the former, but if we can institute long-term management it may reduce the incidence of flare ups.

Three things I learned: common mistakes in the emergency room (ER)

 
Why I love webinars: because Hero lounges on my desk while I learn. Everyone wins!
I’ve been trialling the services of VetGirl, a subscription-based pod-casting, webinaring, veterinary continuing education provider. Last week I enrolled in a webinar on Common Mistakes to Avoid in the ER, with Dr Justine Lee.

I enjoy Justine’s candour and style. She started the webinar by admitting that she was not an A student, she shares her worst experiences (they are, after all, probably the things that we learn from most) and her passion for ER is as palpable as a grade 6 heart murmur.

She discussed what she considered to be the top ten mistakes that are made in emergency situations. So I’m picking three that I found helpful.

  1. Not doing enough chest radiographs (in dogs): this is especially important in geriatric patients. Dr Lee agreed that thoracic radiographs are often a low-yield test but the impact of a positive met-check changes everything. If the patient won’t allow a DV or VD at least two opposite laterals gives a reasonable indication of the presence of mets. Of course in dyspnoeic cats we should possibly be performing less thoracic radiographs (more TFAST and chest taps). Dr Lee has discussed this in more detail in a previous webinar.
  2. Using shock rates of fluids: the textbooks cite shock rates as 60-90ml/kg which is almost the blood volume of the animal and really is overdoing it – especially in cats. Dr Lee recommends bolusing smaller amounts (1/4 to 1/3 of shock rates) over a variable time period (e.g. if it’s a cat with a gallop rhythm this might be given over an hour; if it’s an unstable GDV it might be administered over 20 minutes). This can be repeated several times.
  3. Using the wrong dose of steroids: older textbooks recommend 4-6mg/kg of dexamethasone sodium phosphate for just about everything including shock. But dex SP is 8-15x stronger than pred. Dr Lee recommends treating animals with IV fluids, blood products and vasopressors for shock, and if dex SP must be used, less of it (e.g. 0.01mg/kg q12hr IV for anti-inflammatory effect and 0.25mg/kg q12hr IV).

What is anthrozoology exactly?

Pauleen Bennett.

Earlier this year I had the pleasure of interviewing Dr Pauleen Bennett, Chair of the Australian Anthrozoology Research Foundation

Anthrozoology is derived from the Greek 'anthropos' (meaning human) and zoon (meaning animal). Translated, roughly, that means the study of human-animal interactions. And there's plenty to study in relation to companion animals. Even making sense of pet ownership raises many questions - from an evolutionary perspective, it doesn't make sense that we pour so much attention, care and resources into caring for someone else's baby.

But we do. Pauleen is a brilliant scientist, but she's also a big-picture thinker with a positive outlook. She works on diverse projects but when I asked her for the common thread she answered immediately:

What I am really trying to do is save the planet. We can’t save the planet without fundamentally changing how we think about the environment and animals in it. Most people think through their pets – they don’t think about the polar bears in the Arctic going extinct, they don’t think about the chickens in factory farms. But every single day they are confronted by their cats, dogs and rabbits – and forced to think about how these animals experience the world. So if the only hope of saving the planet is to change the way we think about things, our pets are absolutely instrumental in that. It’s a fairly lofty goal when you think about it.
You can read the full interview in The Veterinarian Magazine (click this link) and you can listen to a podcast of Pauleen talking about pets here.
