Companion Animal Hospital is a full service veterinary hospital located in the Crossroads area of Bellevue. We have been in business in this location since 1998, when Companion Animal Hospital merged with Crossroads Veterinary Clinic into a 10,000 square foot facility built just for our hospital. 

Our veterinary practice strives to practice preventive medicine in order to minimize the risk factors associated with many diseases. We believe the annual, and sometimes biannual exams, can be of greater importance than annual pet vaccinations given without an exam.

By practicing this premise, we are able to slow and possibly stop the progression of many different diseases. This approach to veterinary care allows your pet to live a longer, more comfortable life.

We have a number of resources for you to learn about how to take better care of your pets. Browse around and look at our various educational articles, blog posts, dog & cat boarding services and pet videos. The best veterinary care for animals is ongoing nutrition and preventive care. If you have a question please call us at (425) 746-1800 or fill out our contact form and we'll get back to you as soon as possible.

At Companion Animal Hospital, we treat your pets like the valued family members they are. 

Our pet clinic offers a wide variety of veterinary services, including:

Please Note: We do not offer grooming services

Dog and Cat Boarding Services

Whether you are planning a vacation or need to go out of town on a business trip, you may need to find a reliable option to take care of your dog. At Companion Animal Hospital, we offer boarding services, providing your pets with the love and attention they need while you are out of town. Your dog will be supervised all day and getting plenty of attention from our loving staff. We make sure they are stimulated and engaged, getting plenty of exercise. We make sure your dog is eating well and is playing safe. Our dog boarding team cares about your dog's overall well being, just as you do. Our cat boarding offers a quiet room, with cat condos and a window to watch the outside world. The next time you need to go out of town, make sure you bring your furry friend to Companion Animal Hospital to make new friends!

Check-Ups & Pet Vaccinations

At Companion Animal Hospital we understand that your pets quickly become one of the family. Unlike a child who can tell you what is wrong, your pet can't tell you when something hurts. That is why you should bring your pet in for annual check-ups so your vet can determine any changes in your pet's health. Regular check-ups also give your vet the opportunity to make sure vaccines are up to date. Vaccinations are very important for your pet as they will help prevent serious diseases. Common pet vaccinations include distemper, leptospirosis, Bordetella (kennel cough), rabies, and others. If your pet needs to be updated on the recommended vaccines, please contact us today.
