Dr. Rob Butler DVM, CVA, CVCH, CVFT

Dr. Rob Butler

Having grown up in Connecticut with his Canadian born parents, Dr. Butler attended one year at Carleton University before transferring to the University of Guelph where he graduated from Ontario Veterinary College in 1988.

Loving the convenience of living in a small city while having easy access to the beautiful countryside, Dr. Butler was very excited to accept his first job offer as a veterinarian at the Guelph Animal Hospital in the spring of 1988 and became an owner of the practice shortly after. He has since been joined by Dr. Ilana Smolkin and Dr. Renee Fleming, as co-owners.

As a medical professional, Dr. Butler’s greatest satisfaction comes through helping his patients experience wellness. In pursuit of this goal, early in his career he started to seek out additional tools that could help him achieve better ways to approach the many complex and chronic conditions he was seeing in his daily practice. He discovered that even with significant advancements in modern surgery and pharmacology there were still many conditions that failed to fully respond and he wanted to know how best to keep his patients healthy. Dr. Butler was determined to pursue the highest quality continuing education available in order to integrate the best of conventional medicine with other proven modalities in the treatment of his patients. Thus began his over 15 years of advanced studies in the areas of Acupuncture, Chinese Herbal Therapy, Food and Nutritional Therapy and Bioregulatory Medicine.

Dr. Butler is a Certified Veterinary Acupuncturist, a Certified Veterinary Chinese Herbalist and a Certified Veterinary Food Therapist. He has studied with the International Veterinary Acupuncture Society (IVAS) (www.ivas.org), and with Dr. Steve Marsden (www.naturalpathclinic.ca/bio.html), as well as completing advanced studies in Acupuncture, Chinese Herbal Medicine, Tui-na and Food Therapy at the Chi Institute (www.tcvm.com) in Florida under the direction of Dr. Huisheng Xie (www.tcvm.com/faculty.htm). Dr.Butler has further expanded his training in the area of Bioregulatory Medicine and Homotoxicology with the College of Integrative Veterinary Therapies (www.civtedu.org).

Dr. Butler has been married to his wife Marian since 1990. Marian was born and raised in Guelph, her father having taught at the Ontario Veterinary College for over 35 years. Together they have raised 3 children and share their home with their dog, Odie, a Border Collie/Shepherd cross who sometimes accompanies Dr. Butler to work.

When he is not practicing veterinary medicine, Dr. Butler may be found cycling the back roads of Guelph, practicing martial arts, kayaking the waters of Georgian Bay, or out golfing with a few friends. Dr. Butler remains an active member of his local church having served as a board member for a number of years with a focus on living out the Christian faith while engaging the community through various means of service and missions both locally and abroad. Dr. Butler is currently on the Board of Directors of Bracelet of Hope, a grassroots organization founded in Guelph that is addressing the AIDS pandemic in Lesotho Africa by supporting health, homes and jobs.


Dr. Ilana Smolkin DVM

Ilana and PistachioFear Free Certified-Professional
Dr. Smolkin grew up in Toronto with her parents, 2 brother and a miniature poodle named Princess. From a young age she stated to her parents her intent to become a veterinarian and work through high school and university to realize that dream. She moved to Guelph to attend the Ontario Veterinary College and graduated in 2003. During school, Dr. Smolkin acquired her 2 cats: Ella and Bennett who are still with her today.

Her first year after graduation, Ilana did an internship at a speciality and emergency clinic in Memphis, Tennessee. There she learned a lot about medicine and cancer treatments for pets as well as BBQ and Blues. Six months in, while working an emergency shift, she was brought a sickly 3 week old puppy that was found tied up in a plastic bag. She agreed to foster the pup until old enough for adoption. Mackenzie never left her side until the end.

After a year in Memphis, Dr. Smolkin returned back to Ontario and has been at the Guelph Animal Hospital since. She lives with her husband Carlos, daughter Robyn and her current crew of furry children: Nacho, Dos Equis, Ella and Bennett.

Through the care of her dog Mackenzie, Dr. Smolkin learned the value of integrative care. Mackenzie’s health issues stumped specialists and had no diagnosis in western medicine. The only agreement the specialists had was that Mackenzie’s condition was serious and she might not live out her 5th year till the end. Through an integrative approach, she was able to keep Mackenzie happy and healthy until over 13. She is certified through the College of Animal Chiroprators in the human world would be known as a Chiropractor however in Veterinary medicine the term is Manual Therapy Specialist. In 2014, she added training in bioregulatory medicine and homotoxicology with the College of Integrative Veterinary Therapies. In 2106 she completed training in Western herbal Medicine and was part of the first class to be certified in Animal Normalization therapy which are osteopathic techniques for animals. Most recently in 2017, Dr. Smolkin has become certified in Traditional Veterinary Chinese Acupuncture. She enjoys working with her ever talented Agility patients making sure they compete at their best as well as helping senior patients stay as comfortable as possible. She has found her passion in using an integrated approach to treat all sort of health issues or as preventative medicine.


Dr. Renee Fleming DVM

Renee and Ella

Dr. Fleming first joined Guelph Animal Hospital as an associate in 2006, and she was welcomed as partner in 2009. She grew up in a small town north of Guelph (Hanover) and has made Guelph a permanent home since 2000.

Dr. Fleming attended the University of Guelph, graduating with her Bachelor of Science in Biomedical Studies in the fall of 2000, and she started the Doctor of Veterinary Medicine program at the Ontario Veterinary College that same year. Dr. Fleming has always had a passion for exotic and wild animal medicine, and during veterinary school traveled to South Africa for a few months to assist with Dr. Markus Hofmyer at Kruger National Park. She has assisted with the medical care of African elephants, white rhinoceros, giraffes, lions, and many antelope species. One of her fondest (and most terrifying) memories from that trip was monitoring an African lion as it recovered from sedation after being tested for tuberculosis. She learned that lions can startle quickly upon recovery from anesthesia!  One of her most memorable experiences from that trip was the sedation of a white rhinoceros that had been caught in a poaching trap.  She sustained a deep and badly infected wound on her limb, which Dr. Hofmyer was able to treat.  To be able to assist in her care – such a giant and majestic animal – was so memorable and humbling.

Her taste for adventure has not lessened over her years in practice. She and her husband both enjoy traveling, and the more remote the better! Most recently, Dr. Fleming and her husband successfully reached the summit of Mount Kilimanjaro( 5,895 m) in Tanzania, Africa! After the climb, the Fleming’s traveled to Zanzibar, a small island off the coast of Tanzania, where Dr. Fleming volunteered to perform spays and neuters for the community of Stone Town with the World Society for the Prevention of Cruelty to Animals (WSPCA).   The surgical suite was a trailer fully equipped with sterile equipment, but quite different from the surgical suite at Guelph Animal Hospital!!  All animals were anesthetized with an injectable anesthetic (vs an inhalant anesthetic that we use here in our hospital) so Dr. Fleming has lots of experience being quick with her surgical procedures!

Dr. Fleming spends much of her time volunteering with a focus on animal and children-based charities.  She has traveled to Nunavut and Turks & Caicos with the Canadian Animal Assistance Team (CAAT) to participate in spay/neuter/vaccination/deworming programs.  She will be traveling again to St. Lucia this spring to participate in a large spay/neuter program (again with the Canadian Animal Assistance Team).  These volunteer trips are very important to Dr. Fleming, who feels strongly that professionals should contribute back whenever and wherever they can.  She has spayed or neutered over 400 animals as part of various volunteer programs.  She also volunteers locally for the Children’s Foundation for Guelph & Wellington (CFGW) and our entire hospital avidly donates regularly to CFGW events.

While at the Guelph Animal Hospital, Dr. Fleming can be found tending to anything with fur or scales. She sees the majority of our small mammal patients (rabbits, ferrets, rats, chinchillas, lizards etc.) and treats them with the same caring and compassion that she does our dog and cat patients. Her most avid area of interest is pain control – both surrounding surgery and for chronic conditions such as arthritis or cancer. She is currently working on her certification for the International Veterinary Academy of Pain Management (IVAPM), as well as her acupuncture certification. In addition, Dr. Fleming is our Emergency Care Specialist. She has over 9 years of experience working at a busy after-hours emergency hospital.

During quiet times, Dr. Fleming can often be found cuddling with a post-operative patient as they recovery from surgery.  She also has special affinity for pets with ‘squished’ faces – she is our resident bulldog expert!  She has owned both English and French bulldogs and will (hopefully) never be without one in her family.  Dr. Fleming has bulldog patients from Toronto to Windsor and adores them all!!  If you are not aware, the short-nosed breeds are prone to a variety of health conditions (they can have airway/breathing difficulties, dental abnormalities, and a variety of other concerns) and she is dedicated to educating pet owners about their health risks and assisting in preventative care to help ensure a lifetime of health and happiness.

Dr. Fleming and her husband John share their home with a very spoiled mix of critters!  Currently, they have Eleanor Bee (or Ellie) – a lively 3 year old English Bulldog – and 3 cats:  Mu, a gentle 14 year old kitty, Maui, a handsome & cuddly 6 year old  kitty, and Ragnar, a spunky 2 year old Sphinx.  All of Dr. Fleming’s cats were rescues, with Maui needing the most intensive treatment – an extensive surgical repair to his diaphragm and his hip after being hit by a car.  They also extended their family to include the two legged sort – they have two boys – Ewan (aged 4) and Asher who is one year old.

Aside from traveling and spending time with her two and four-legged family, Dr. Fleming loves running, boxing, and manages to make quilts in her spare time.  She couldn’t imagine herself in any other profession, and you can trust that she will treat your pets with the same love and attention that she does her own.


Dr. Michelle DePass DVM

Michelle and Kaya
Dr. Michelle DePass joined us in the summer of 2016. She graduated from the Ontario Veterinary College in 2015 after completing her Bachelor of Science in Biology at Queen’s University. She grew up in the small town of St Andrew’s West outside of Cornwall, Ontario.

Growing up in a rural town she was always surrounded by animals, knowing from a young age that she wanted to spend her life helping and treating animals. During the summer of 2013, Dr DePass travelled to Guatemala to provide volunteer
veterinary care to communities in need through the Global Vets program. She worked with a wildlife and rehabilitation centre, stray dog/cat spay and neuter program and an overpopulated no-kill shelter.

Fear Free Certified-Professional-Logo-300x134
Dr. Elad Rosenfeld graduated from the Ontario Veterinary College in 2016 after completing his Bachelor of Science Agriculture in Animal Sciences at The Hebrew University of Jerusalem, Israel. Dr. Rosenfeld worked for several years as a veterinary technician in Israel before continuing his education to pursue his dream of becoming a veterinarian here in Guelph.

For as long as he can remember, he was surrounded by animals of all kinds. Elad grew up in the small rural village, Nataf, Israel, where he was playing with basically anything that moves including dogs, cats, worms, insects, snakes and scorpions to his mother’s dismay.

Elad enjoyed living and working on a dairy farm, Kibbutz Ketura, in the south of Israel for a couple of years, milking cows and carrying out herd health tasks with the veterinarian. In addition, throughout his Bachelor degree, Elad worked as an emergency dispatcher for animals in distress .

Dr. Rosenfeld has a keen interest in animal behavior and is a Fear Free Certified Practitioner always striving to alleviate fear and stress from the pets he meets at the clinic in order to create a positive experience for our furry friends and to strengthen the human-animal bond. His other interests include Internal and diagnostic medicine and surgery. He looks forward to further extend and deepen his knowledge in animal behavior as well as other continuing education including dentistry, ultrasonography and more.

Elad lives in Guelph with his wife,Gila, two daughters, Maya and Ella, their dogs, Paddy and Whiskey and Cookie the hamster.

Outside of work he enjoys playing guitar, riding his bicycle, soccer, hiking, camping and everything outdoors.


Dr.Meredith Geldart DVM

Meredith and Cheyenne
After 10 years of veterinary practice in Caledon, Dr. Meredith Geldart was excited to join the caring team at Guelph Animal Hospital.

Dr. Geldart hopes to contribute to the team via her professional interests, including internal medicine, soft tissue surgery, anesthesia, radiology and pain control. She hopes to give back to the community with her work as a member of the College of Veterinarians Discipline Committee and volunteering with Community Vet Outreach in Guelph.

Like many kids, she always knew she wanted to be a veterinarian. It just made sense for her to pursue a career to try to repay animals for all the ways they brighten our days. Dr. Geldart’s goal has always been to help sick pets feel better and keep healthy pets happy so they can have as much quality time with their families as possible.

During her time at OVC she worked with shelter animals at the teaching hospital, where she found her beloved Rotti, Mackenzie. Sadly, Mackenzie recently passed away, but this left a space her newly acquired geriatric rescue cat, named Peppa Susie Sheep Catty Batty by her very creative 3 year old.

Dr Geldart is busy outside of work with her 2 boys and husband Christian. Any free time is spent petting neighbourhood kitties with her kids, chasing backyard bunnies, running and playing soccer.


Dr. Jen Perret DVM


Jen and Dobby
Dr. Perret joined us in the spring of 2013. She graduated from the Ontario Veterinary College in 2009 after completing her honours biology degree at Queen’s University. She grew up in the Okanagan Valley, in BC, and has worked at a number of different in practices on Vancouver Island, around Southern Ontario, and in Oxford, England.

Throughout her childhood, Jen was prone to bringing home any number of animals – from garter snakes to flea-ridden kittens – and considers herself extremely lucky to have had supportive and understanding parents! She has had a variety of pets including aquarium fish, turtles, budgies, hermit crabs, mice, and cats. Her current life partner is an older dog, Lilith, whose main interests include barking at strangers and long walks in the sunshine.
