A horse isn't a pet in the same sense as a dog or cat. It won't curl up in a basket to sleep or fetch a stick. And you sure don't want one jumping up on your lap.

How often is too often when it comes to your pet's vaccinations? It's a question more and more pet owners are asking these days. Mounting debate about the need to vaccinate animals annually, along with concerns about a possible link between vaccines and rare cancers, may leave many pet owners confused about how often to visit the vet for vaccinations.
