What Our Customers Say About Us

“Dr. Michelle Thomas and the staff at Mulnix Animal Clinic are the best! I've been going there for over eight years and have always received compassionate care for my numerous furkids. They are very accommodating and go above and beyond in the services they provide. First class all the way! I would never consider going anywhere else!”

Deb/Fort Collins, COCustomer

“We recently switched to Mulnix and love it! Dr. Gaffney is incredible. They were able to squeeze in my dog today after she tore her nail playing in the backyard. They show great care and concern for my dogs, remember my name, and are very good at explaining procedures and various treatment options! It's a great clinic. The pricing is very reasonable!”
