The staff is wonderful. We trust them implicitly with the care of my babies. We have peace of mind knowing there is always someone on call if ever there is an emergency.

He has treated our dogs who’ve gone on to Dog Heaven and our current Cavaliers. We cannot put in the right words how much we appreciate the excellent vet care we’ve received from Dr. Choyce and the staff at All Pets.

Harry & Brandee Standley

We have received excellent care and service for our Westie from All Pets Animal Hospital for eight years and counting. We also use them for boarding when we go on vacation as our dog receives such loving care from the entire staff that she returns home like she has never been gone. A "five out of five stars" rating with a "highly recommend" from us.

Denny & Cheryl Daniels

I liked the level of compassion shown toward our pets and the office’s understanding of how much the pets mean to their owners. I particularly enjoyed being able to observe the surgical procedure and appreciated the commentary relative to any milestones during the process. Dr. Choyce and his group treated our pets as if she were one of their own dogs.

Rob Walters for Anthony Barrientos

Everyone was excellent! My dog Raleigh was seen immediately and treated kindly. Thank you so much for being so nice to our family!

Stacy Barber

Dr. Choyce’s expert and professional approach are exceptional. I would recommend All Pets Animal Hospital and its services and personnel to any caring pet owner.

I like using All Pets Animal Hospital for routine veterinary care, and I like that, if we have any emergency, we already have a history with them on our pets.

Valerie Pyland

I love it here. The staff is very friendly! We brought our puppy here because she was very ill, and as soon as we brought her home, she was back to normal. Everyone is very professional. This is the place I will continue taking my pets to get their check-ups.
