What Our PET PARENTS are saying

“I came to this facility on two occasions with two different dogs. I cannot say enough good things about this facility. The entire staff, along with the veterinarians, far exceeded my expectations when it came to service, compassion, and pricing. Thank you for helping me with Rosie and your help with Buddy.”

My puppy had an ear infection and our vet was unable to get us in for a few days so we found this urgent care. The staff was incredibly welcoming, professional and attentive, both on the phone and as I waited in the tented area out front. When the vet came out to talk to me, he was warm and completely unrushed, explaining to me the treatment as well as possible causes and an inexpensive preventative measure I was completely unaware of. It did end up taking about an hour and a half but it was overall a better experience than my highly recommended vet – and $20 cheaper for the same problem. Highly recommend!

“Absolutely had a very good visit addressing Charlie’s issues. Dr. Welsh was extremely detailed and took the time to explain options/recommendations for diagnosing the issues. The medication, treatment and routine prescribed by Dr. Welsh has made 100% difference. It’s been almost 2 months, and we have been having fun beach days with great results. Definitely would recommend Dr. Welsh and the team at AVSG. Thank you for taking care of our best friend. AVSG staff were friendly and extremely caring.”
