Can puppies get bloat? I just got off the phone with the overnight person and we have a 5-6 month old pit mix puppy, about 20 pounds, that has suddenly (as in the past couple hours) become letharic, very bloated and has picked up what seems to be a slight cough. Earlier tonight she had diarrhea. She drank a whole bowl of water and is keeping that down for the time being. The overnight is calling the e-vet for their opinion as I type this (I'm at home and about ready for bed).
