We are very fortunate to live and work in this wonderful community. Not only do we have the privilege of caring for your beloved pets, we also have the opportunity to learn about you and your families as well. Our conversations are not always about veterinary medicine. They are often about other battles in your lives. It may be a family member battling cancer, an aging parent, or an autoimmune disorder of a close friend. The fact is, we are all connected and we all know people who are vulnerable at this time. In the coming months, our primary goal is to be able to provide care to your pets, while also doing our part to slow the spread of COVID-19 to protect those who are vulnerable in our community. And we must do this without spreading fear. 

We are offering curb-side pick-up – call ahead (613-382-2900) and we will bring food and medications to your car, and we can meet you outside to bring your animal in for physical exams. The doctor will come out to speak to you, or will call your cell phone, to discuss his/her thoughts and findings as well as the treatment plan that works best for you and your pet.

We have a vet store for online orders of pet food: This will allow fewer trips in to the clinic. 

As always clinic disinfection is very important within the clinic and we are taking care to maintain and exceed our already high standards in this area.

This is not a time for fear. This is a time for community. Let’s all do our parts to take care of each other. 


 Dr. Scott Stevenson and the 

Thousand Islands Veterinary Services Team


We also understand that the experience of coming to the vet clinic can make some pets nervous. We are striving to change that! We want all of our clients and their pets to feel as at ease as possible when they come in for an exam. We employ many different techniques to further this goal and we can give you tips and ideas of things that you can do at home to make your visit to the vet clinic as stress free as possible for you and your pets. We recently added on a new exam room that is gearing mainly for our feline patients! This room is on the other side of our office so that we can try to separate the cats from the dogs and try to lower the kitty's stress levels that way. This new exam room also features, a diffuser that emits 'happy cat' pheromones to help to lower anxiety as well as a tv that has an aquarium playing as well as fun wall shelves for the kitties to climb on while the vet and his/her owner talk.
