They didn't do blood work just a fecal. Gave him antibotics and it cleared up. When Rosco finished medicine the nasty poops came back again. Took him back to vet and they gave him more meds. When he finished them back came the poops. After much reading on here it sounded like IBD so I took him off all human foods and giving nothing but dog food to see if there was a difference. So far his poops are a big improvement. I was giving him more human foods than dog food. My bad
. He doesn't like the adjustment to dog food. I guess if I was him I wouldn't either after eating human food.
