I just had Buster at the vet Friday due to diarrhea, diagnosed with "garbage gut" and put on Flagyl (7 days) and probiotics (10 days). Saturday his stool firmed up, best we've seen with him (battled intestinal worms since we got him at 9 1/2 weeks). This morning he was loose, soft but formed. My brother in law cared for him all day while my husband and I were out of town, he mentioned the same thing...soft but formed stool. Around 8pm we noticed blood on Busters rear leg, couldnt find a source, checked his mouth and found his gums bleeding a bit. About 20 minutes ago (midnight central time) I noticed bright red blood on a white rope toy, checked his mouth and found he'd lost his first puppy tooth With all 4 of my girls we dealt with nasty diapers. Has anyone noticed this same thing with pups?
