The last couple of days he has been lethargic and mopey. He keeps drooling which he has never done before. His appetite is fine though and he has no problem going to the bathroom. Do you think I should take him to the vet? He just looks so sad and that is not like him!
ETA: It looks like his throat or neck is swollen. Do dogs get sore throats or strep? It it possible for them to get swollen glands in their neck?
Update: So I took Henry to the vet today and they did x-rays and an asperation to see what the mass was in his neck. They wont have the results until wednesday but they said it is possible that it could be a cyst or tumor How can this happen? He is only a year old.
