To protect against rabies, dogs are given shots every one to three years, depending on such factors as their age and the type of vaccine used.
But a Maine woman who is concerned that too-frequent rabies vaccinations are exposing pets to health risks has helped raise money for a study to look at whether dogs actually need far fewer shots.
The study at the University of Wisconsin-Madison School of Veterinary Medicine will examine whether rabies vaccinations immunize dogs to that fatal disease for as long as five to seven years.
