kitty1.pngAppointments

Our appointment book is computerized, which allows us to efficiently make appointments for you and your pet. Our receptionists and team will attempt to accommodate all requests to the best of our ability. Emergencies are accepted anytime our clinic is open. If you feel you have an emergency with your pet, please call us or come in immediately. If possible it is best to call before coming in so that a staff member can advise you on your particular emergency.

Emergency & Urgent Care

We have a veterinarian and personnel on duty six days a week who are trained and equipped to handle any urgent care your pet has. Usually an emergency team consists of at least one veterinarian and several technicians working together to save a pet's life. Emergencies can be things such as accidental ingestion of rat poison, hit by car, and chocolate ingestion. If you ever feel that your pet needs emergency treatment do not hesitate to call or come in immediately.

We are also available for urgent care when the condition is not life-threatening. If you feel your pet needs to be seen before you are able to get an appointment, our veterinarians will work to "squeeze" you in between scheduled appointments. When you arrive, our receptionists will be able to give you an estimate on how long you may have to wait in order to be seen.

Testimonials

Read What Our Clients Say

  • "We have been going to Companion Animal Hospital for over two years. The staff at Companion Animal Hospital is the most caring and considerate group of people who treats all of our "kids" like they are their own. We are very fortunate to be able to call them and have them there when we needed them. Awesome service!!"

  • "I found this place about 7 years ago when I was desperately calling around to see if a doctor would be willing to work on a Saturday to perform emergency surgery and save my pup. The receptionist called Dr. Lee and he agreed to drive back early from his church retreat for a 6 p.m. surgery ON A SATURDAY. We are in Orange County now, but we still make the drive so our sweet dog can see Dr. Lee for check-ups. I am forever grateful."

  • "A few years ago we had do put our 16 yr old Charlie to sleep because he had a stroke. They were so caring and compassionate. They gave us all the time we needed with him. Now it looks like we will need to take out 15 yr old yorkie :(. We won’t take her anywhere else."
