Pender Vet is an outstanding outfit. I changed to their services when we brought our sick dog to our local vet and they told us they were closing and we had to take our dog somewhere else. Pender is open 24/7 and I have been very happy with every vet visit we have had, routine and emergency. Any time I have a question I have called and spoken with a vet tech immediately and I can't tell you the peace of mind that gives me when I'm worried about my dog's health! I have three dogs and have been to both Pender Vet in Fairfax and the one in Chantilly and am so very happy with the services.
