This review is for the mobile vet staff that does the vaccination clinics at Petco every Tuesday evenings. They are AMAZING. I have a dog that is temperamental around other dogs and can be dog aggressive when she gets stressed out. They completely understood and offered to go into another aisle to do the shots. They took their time allowing my dog warm up to them before they did any shots and were very patient. Great staff and very friendly! Vaccines are offered in packages at a discounted price.
