Our Services

At Anza Animal Clinic, we are committed to keeping your pet healthy and happy through the years, which is why we believe every pet deserves the best personalized care possible. We seek to develop long-term relationships with pets, tracking their progress, and helping them feel comfortable whenever they visit our pet clinic.

Proper veterinary care requires a team that has a clear vision of holistic pet health, all the way from the basics of a general exam to complex surgeries that require an organized and dedicated staff. We aim to provide that level of service from the moment you and your pet walk in the door.

Our Clients Are Our Fans

and they know how to cheer us on!

We have been placing our pets in Dr. Watasi’s care at the Anza Animal Clinic for over 20 years. He has saved our pets lives many times. He is an excellent doctor and very knowledgeable as well as compassionate.

So glad I came here! Amazing Doctor & staff. They were so helpful and caring unlike other vets I’ve been to. If your dog has any issues…this is the place where you want to be. They are detail oriented and that to me means everything. Thank you so much!

Really great professional, helpful, and friendly staff all around. After the first visit I knew I would be returning and I have since as well as had them perform a spaying that went absolutely perfectly and again, so easy and my cat does not mind coming here at all either!

“Trustworthy” is the best word to describe my veterinarian. Our pets are family and unfortunately except for their facial expressions and body language they really cannot convey what they feel as much as we would like. We need to know that our Doctor’s primary concern is the well being of our pets and not how much they could bill. I have been bringing my 14 yr. old black “Pearl” Lab to Dr. Watase at Anza Animal Clinic and I completely trust his work and judgement every time. I also have to say that the staff at Anza are all so great and wonderful. You can see that they love animals and will treat your pet as if they were their own. I have had quite a few dogs and have tried several vets. Dr. Watase and the Anza staff are the best in what they do.

Anza took my dog in on an urgent basis when all of the other clinics in the area refused, including the local emergency vet clinic, because they were at capacity. I am so grateful to Dr. Watase, he was so patient, eased my anxiety, and was very thorough. He called to check in on my fur baby the next day and was able to further guide me by having me email him pictures of my concerns rather than making me come back to the clinic. It is clear the Anza team love animals as much as I do and I’m so thankful to have found them. Would highly recommend this clinic!
