About Us

Vista Vet Animal Hospital & Pet Lodge

is pleased to be open serving the veterinary and boarding needs of Round Rock and the surrounding communities. We are privately owned and pride ourselves in our philosophy that veterinary care must be tailored to each individual patient. Veterinary medicine is not “one size fits all”. From our vaccine protocols to anesthesia, surgery, dentistry and diet, each patient is individually assessed by our doctor(s) and we educate and communicate with our clients to derive the best healthcare plan.
