· What is mobile veterinary surgery?

If after examining your pet, your veterinarian decides that surgery is the best possible course of action, he/she contacts us and our board-certified surgeon travels to their hospital to perform surgery.

· What are the benefits of using a mobile surgeon?

Comfort, Familiarity, Time and Money! Many pet owners have developed a strong rapport with their family veterinarians and having your pet’s surgery at the comfort of their facility makes the whole process smoother and less stressful. In addition, not having to take your beloved pet to another hospital to be treated saves you time, minimizes stress, and ensures that your pet receives the same level of care at a more affordable cost!
