Hello, my 4 year old Staffordshire Terrier all of a sudden has become sick and we don’t know what is going on. He has suddenly started to cough which ends with him gagging. He doesn’t want to eat and just lays around sleeping. Occasionally, he will get the shivers. He has still been drinking water and will still go out to use the bathroom. I just hate seeing my little ball of energy looking so tired and miserable. I’m wondering if it’s kennel cough that has progressed or something of the sort. Anyone have any opinions or ideas of what it could be or what I can do to help him? We have very limited income right now.
