I have the same dog and never knew what he was. Saved him from traffic on a freeway so I named him Freeway. Smart as a whip. Crate trained, house trained, crys for us to let the ferrets out so he can play with them but loves to chase squirrels.He has super smelling and sometimes his nose gets him in trouble. If we eat in the living room he will stay in the kitchen till we pick up the plates. Excellent dog.
