My sister found this dog on her land last night. It is very skinny and looks to have not eaten for awhile. He is all black other than some white on its feet. They estimate his age to be 8-12 weeks. At first glance he looks like a Labrador, but I think he has to be some type of mix breed. I am going to adopt him. My sister is bringing him in on Friday and I am taking him to the vet. Does anyone have any ideas as to what he might be a mix of?
