Sydney Specialist Veterinarians

Specialist veterinarians exist across many fields namely surgery, internal medicine, oncology, dermatology, diagnostic imaging etc. In order to be registered as an Australian specialist requires a minimum of 3 years additional veterinary training under the supervision of other specialists followed by successful completion of a rigorous examination process by a recognised governing body. This registration ensures that your pet is afforded the highest standard of care.

Consulting Animal Specialists are a Mobile Veterinary Service that brings the specialist to you. We differ from traditional specialist referral hospitals in that the specialist comes to your local veterinarian to consult and perform the necessary procedures on your pet.

Your furry family member is therefore treated and cared for in a familiar environment close to home.
