I've had pets as patients at Vet Stop for over 20 years. This is the only vet I will ever use. The staff is very caring and attentive and Dr. McKnight is the absolute best!

Very attentive. The Doctor remembers everyone of my pets by name.

The doctor and technician were very friendly and loving to my dog and gave her lots of treats. This was her first appointment since her initial puppy visits so she wasn't familiar with where she was and I am hoping that the treats and love that she was given will trump the shots so she isn't fearful next year. I switched to Vet Stop years ago with my other pets because the pricing is more reasonable than most vets. Love this place and the staff!

We brought in our foster GSD. We were very pleased. We are considering using Vet Stop for the rest of our furkids.

Vet Stop is the BEST in town!!! I've been taking my dogs there for over 15 years and will continue!! They have the most caring and compassionate staff that understand how precious our furry friends are and they give them the same love and attention that we do.

My cat is back. I took Jenny to a vet near my home three times and my cat did not get any better, so I went back to the Vet Stop where I first went when I adopted her. After taking the medicine that she was given, she is now running through the house like someone is chasing her and eating her food again. Unfortunately, she has decided it is okay to jump on the kitchen counters again, but I can live with that. At least for a little while. Thank you doctor.
