We are a group of two Companion Animal Hospitals accredited by the College of Veterinarians of Ontario, the licensing body for Veterinarians and veterinary hospitals in the province. Established by Dr. Sandi Rosely, Avonlea Animal Hospital has been serving the Mississauga Meadowvale community since July 2000. In 2007, Hollybank Animal Hospital opened to service the growing neighbourhoods in south Milton.
Choosing your pet's doctor and health care team can be a very difficult process. We can assure you that all of your pet's health care needs will be met with our hospital staff and services. Our pet care health services include wellness care, vaccinations, medical care, surgery, dentistry, x-rays, and behaviour, obedience and dietary management.
Behaviour problems are very common amongst pets. Some common conditions include separation anxiety, destruction of the home, fear and territorial aggression and house soiling. Many of the problems have a congenital and an environmental component. Our doctors are trained to help you determine the cause of the behavior problem and then advise you about how to […]
DENTAL DISEASE Almost every pet will experience some degree of dental disease in their lifetime! Plaque bacteria thrive in your pet’s mouth (ever smelled that ‘doggy’ or ‘kitty’ breath?). At first, they just live on the surfaces of the teeth and gums, but if not removed regularly by brushing or wiping, they will infect the […]
Annual Health Assessments Bringing your pet in for their annual visit is still one of the most important things you can do for his or her preventative healthcare. You can bring any questions or concerns about your pet for the veterinarian to answer. The veterinarian will ask you several questions to find out how your […]
Sometimes your pet’s behaviour/actions can tell us they are not feeling well, but other times your pet can hide disease really well. This is why annual examinations and bloodwork is so helpful. Many medical conditions can be found and treated easily with regular veterinary visits and bloodwork. At Avonlea Animal hospital we believe that your […]
MICROCHIPPING Despite your best efforts, accidents can happen and your pet could go missing. Thousands of animals end up in shelters every year. Unfortunately, many of these animals are never reunited with their families because they can’t be identified. A collar tag is a great way to identify your pet; however, if this were to […]
Just like in humans, nutrition is an important cornerstone for the health of your pet. And just like in humans, nutritional requirements change over time, depending on age, lifestyle and medical conditions. For example, cats and dogs with kidney disease require specialized diets, and small breed dogs are often prone to urinary and dental disease […]
Our veterinarians are experienced in providing specialized care and treatment for exotic companion animals, including ferrets, gerbils, guinea pigs, hamsters and rabbits. We understand their unique health needs and can provide diagnostic, therapeutic, and surgical services, as well as counselling on nutrition, behavior, and general care.
Our doctors are available for both routine and non-routine surgeries. Prior to all surgical procedures, the patient will have a physical examination and blood work to assess for any concerns that need to be addressed prior to surgery or at the time of surgery. Presurgical blood testing allows the doctors to assess and ensure your […]
How Ultrasound Works Ultrasonography involves passing a probe over your pet’s skin after the hair has been shaved away, while it emits harmless ultrasound waves (which are like sound waves, but at a higher frequency that we cannot hear). As the sound waves bounce off tissues and structures inside your pet’s body, they are detected […]
When the immune system is exposed to an infectious agent such as a virus or bacteria, it sets to work killing and eliminating it. One of the ways it does this is by making proteins called antibodies that specifically recognize that virus or bacteria and attach to it, flagging it for white blood cells to […]
One of the best things you can do for your pet is to keep him or her healthy. And one of the easiest and least expensive ways to do that is by bringing in your pet for regular exams and vaccinations. Dogs and cats (and other pets) age far faster than people, so significant changes […]
At some point your veterinarian may recommend that your pet have an x-ray (technically known as a radiograph). This is a diagnostic tool that is very helpful to literally see inside your pet’s body. Examples of things that are commonly diagnosed with radiology include: broken bones, intestinal blockages or foreign objects, heart enlargement, lung conditions. […]
I have used other vet services in the past but since moving to Milton I go to Hollybank for all of my dogs needs. The Doctors and staff there are very compassionate and caring. They treat my puppy as if it were there own. From the staff who greet you at the front door to the Medical staff I don’t think I could ask for better. You always feel welcome there. I don’t think I could ever take my puppy anywhere else even if I move out of the area i’m sure I would make the commute. Keep up the great work and thanks for taking care of my new puppy and also the one I just lost after having her for so many years
Very caring, they take good care of our pets.
Been going here exclusively since we rescued our dog almost 5 years ago. The staff and doctors have become an extended family to our four legged friend. Highly recommend to anyone looking for a team that goes the extra mile.
I have always felt very comfortable with the staff at Hollybank and their sister vet. I actually followed Dr. Sandi from one place to another because I didn’t want to change doctors. I was in Mississauga before and was ecstatic that they opened up another practice in Milton. They treat my dog very well, their assessments were very thorough and they are willing to answer any questions I have. They take into account my opinions which makes me feel better because I am able to be involved in my dog’s care.
I took our new pup, Chewy, to this vet few days ago to introduce him and do the initial health check. The staff were very kind and friendly. The doctor was very thorough in her examination and spent way more than enough time to explain the pup on-boarding process. While I’ve read about how scary the first visit to the vet could be, Chewy was very comfortable and spent his time playing around. He even left his mark at the examination room floor 🙂 One of the nice welcoming gestures I’ve noticed was the writing on the white board when we arrived. Thank you and I highly recommend this vet.
Sandy (Dr. Roselli) took care of my dog for 16 years, and we couldn’t have asked for a better vet. She really, truly cared about Sable, and was always available when we needed her. The entire staff at Avonlea are exceptional. Sandy – we won’t forget all the things you did for our family and Sable. It meant the world to us.
friendly and knowledgeable staff & doctor. clean and inviting office space. waiting area is not too large, which minimizes the possibilities of different animals interacting.. My cat likes that he doesn’t have to contend with over zealous dogs! appointments are usually right on time. There are two examination rooms; one of which is reserved for you and your pet at your appointment time. So there will be little to no waiting in the front lobby area, as long as you arrive on time for your appointment. The vet will make all expenses known beforehand. Very upfront with all of the costs associated with the testing and products; no sticker shock after-the-fact like at my last vet’s clinic. staff take the time to make a follow-up phone call to check on things. Even the doctor herself called me, just to check up my kitty!
Changing vets and going to Hollybank Animal Hospital was the best decision ever and has absolutely made a world of difference to us and our beloved cats. We had no idea that vet care could be this great and only wish we’d switched years ago. The outstanding care we’ve received from the veterinarians and staff at Hollybank is absolutely top notch and we couldn’t be happier or more grateful for all they’ve done and continue to do for our cats. THANK YOU!!!
Charlotte loves the treats and attention she receives. All of the staff are kind and knowledgeable. Charlotte loves her vets and staff. Overall I am very pleased with her care and I am happy with the clinic!
Emmie has been going here since she was around 10 weeks old; she’s now 5. Staff are very nice, helpful and knowledgeable.
Thank you so much for caring about Cooper. You all are doing a great job! I really appreciate the follow up phone call. Cooper is doing great! THANKS
Jen and Mike
Great place with wonderful staff! :o) They took the time to follow up with us to make sure our dog Gibson was doing well!
Amazing clinic! They truly care about their patients and offer the highest level of medical expertise for our dog.
The doctors and staff are fantastic! Went for my first visit with Pedro and they were all great. Even when I call for advice. Then today after Pedro had his little man spot taken away and teeth pulled, still amazing before and after the procedures. After all my what I assume must be annoying phone calls checking up on my Pedro they were still so friendly and courteous. Even sent a picture of Pedro recovering! Exceptional skills dealing with Pedro and great communication skills. Not easy to find these days. Very impressed. Love this team!
I am so happy with the care I’ve received for all my pets! Everyone is so pleasant from the front desk up to the doctors. They have handled care from puppyhood through spaying and emergencies with compassion and skill. We have also lost two beloved dogs and one Guinea pig to old age- the empathy and compassion helped us in sad times. I highly recommend Drs Rosely and Johnson.
Thanks to this amazing clinic a wonderful vet and such caring staff. Your compassion and kindness helped us to make the right decision for Bruno Again thank you so much.
Great clinic and very friendly staff! It took a bunch of calling around to find someone who would look at our ferret but I’m happy we found this one. Dr. Johnson was amazing!
Dr. Rosely and staff are amazing. Professional, friendly and empathetic. I just picked up my puppy and was surprised to find that the bill for her surgery had been discounted. I won’t take my puppies anywhere else.
Great clinic and very friendly staff. Just wanted to say a big thank you for all your love and support with my kitty Bruno, who sadly I had to say goodbye to on Monday. You can see your love for animals in your work. Thank you.
