We presently have 2 vets and both admit that our very first vet (in our previous home) is correct in saying that rabies abound in trash and that clean dogs are clean of rabies. Clean dog means our dogs which are kept inside the house and regularly bathed and cleaned. Rabies are spread by stray dogs that rummage in the trash particularly trash that have rotten meat. It's funny because this topic always surfaces when we are having our dogs for their regular vaccine against diseases that includes rabies. So even if our dogs are safe, it is safer if they get the prescribed shots.... said the vet.
