Farm dog

This was one of two dogs that came over to greet us on a farm, while we out doing the annual Audubon Christmas Bird Count in the Cochrane area. I don't know much/anything about dogs, but I was surprised to see a dog with a bright pink nose like this. He also had strange eyes that made me wonder if it was blind. However, it was running all over the place, so seemed to have sight. Can anyone tell me what breed this is and if a pink nose is usual for that breed? Thanks : )
