More: Frosty is a purebred White German Shepherd who was born in a little town called Tamboril, in the Cibao Valley of the Dominican Republic, just outside of Santiago. I have trained him as a service dog for autistic children. He is the lead of my 4 dogs as far as his responsibilities with my son, not only in that he is in charge of his care after me, but he also manages 2 of my other 3 dogs in their tasks with my son. It has worked out so well that my son is a very high functioning autistic child despite being moderate on the spectrum. His interaction with dogs his whole life is the reason.
