Texas veterinarian Ronald Hines is suing in federal court to change state laws prohibiting him from diagnosing and recommending treatment for animals via the Internet. Rules in Texas and other states that are based on model regulations from the AVMA do not allow online veterinary practice. AVMA President Dr. Douglas Aspros said technology may one day allow some safe practice of veterinary medicine online, but not yet. "The rules are not there to protect the vet," Dr. Aspros said. "They're there to protect the patient."
