For about twenty-four hours now, my puppy, Boaz, has had really watery diarrhea. He'ss four and a half months old, has had all of his shots, and otherwise has been acting quite normal. No vomitig, appetite fine, bark-ability fine , energy pretty normal - maybe a bit less than normal. He still wants to chase balls. Mostly it's just the diarrhea. I know there can be a problem with puppies getting dehydrated, so we'll be trying to keep him hydrated. He LOVES drinking, so hopefully that won't be too much of a problem. We're on a pretty tight budget, so if possible I don't want to have to take him to the vet if it's not totally necessary. Is there any advice you dog-lovers can give me, as to what might be causing it (it could be something he ate - he eats EVERYTHING he can get (which we try to keep to a minimum ) ) or how to help firm up his poos?
