I left for work this morning and my Pitt Bull named Killer was fine. He stayed in the house all day until I came home from work. When I came in I noticed that his throat is swollen and the inslde of his mouth is swollen also. He ate a little bit but acts as if its painful to swollow anything. He still wags his tail but isnt as active as he normally is. he wont play or jump around like he normally does when I first get home. He is around 2 years old and has been healthy up untill now. Please any advice or help would be very much appericated!!
