Our Reviews

Thank you for your kind words

Thank you for making Demanes Animal Hospital one of the highest-rated veterinary hospitals! Your kind words mean the world to us, and we appreciate you taking the time to let us know what you think.

We brought our snake in and the vet was so knowledgeable, friendly, and helpful. I would highly recommend them for any of your reptiles needs. We’ll be bringing our furry friends to them as well. GOOD JOB!


They have always been amazing vets to our old man of a cat. Never had an issue or any problems with having to get ahold of someone, and always willing to work with you.

My dog broke his nail and it got swollen and infected. The doctor got us in right away and took great care of our dog. He is very personable and really goes the extra mile to help pets and humans alike!
