Here about 4 or 5 days ago, Gunnar started to, at times sneezing, and at times snorting. When he lays down he is fine (no sneezing, no snorting), but when he stands up he sneezes , and snorts something terrible. Tried getting him into the vet today but they are closed until Monday. He hasn't been nowhere but at home and in the yard for 2 weeks, and we haven't given him anything different then we have before. Its like he has something stuck in his nose. Anyone have any ideas as to what could be wrong? Thanks! Do dogs get colds?
