Yes, it has been an ongoing hot topic in the veterinary world! There is yet another bill in Congress that was introduced this summer that is awaiting review by the House Energy and Commerce Committee known as the Fairness to Pet Owners Act of 2015.
This bill would require that veterinarians provide a written prescription for all medications (other than those given in hospital or acute situations) regardless of whether the pet owner chooses to have them dispensed in the vet hospital or not. I see several issues with this bill (which by the way is NOT supported by the American Veterinary Medical Association.)
