Hi guys, Thanks for all of the responses in diagnosing Andy. I took him back to the vet and he prescribed Amoxi and Metronidizole. Unfortunately, no matter how well I hide the Metronidizole it always makes a u-turn and comes back up. So, for the time being he is only getting Amoxi twice a day. My question is, is ferretvite ok for his ulcer?? It seems to be the only thing that stays down. Even then, I sometimes have to slip him some Pepto when I see him grinding his teeth. He hates the taste but it works like magic in about 15 minutes. He soon after just falls asleep. I only do this about once or twice per day. Is this too much?? Thanks for your help!!
