I have a puppy (got 2 of them now, brothers) who is almost 4 months old. I have had him on raw since early puppyhood. He was doing great on it, using chicken as my main protein with a bit of pork necks as RMB. His poo looked great. Then one day I came home, and he had the runs. It continually got worse to the point of where it was like water shooting out. I tried increasing his bone, giving him 2 chicken backs per day in addition to the pork neck and a chicken thigh. The only thing different I did was add an extra chicken back into the meal. This was all divided into 3 meals per day. He was eating approximately 20-23oz per day. His ideal adult weight will be at least 70-80#. I tried turkey as a main protein source to no avail, and omitted the chicken/pork. It didn't clear it up after a week on this, so I took him to the vet. They checked his poo, no parasites, no worms, etc. He was also checked for parvo (he's had his shots prior to this appt) and it was negative. They put him on Flagyl and it helped for a while. So now I have him on TOTW, and his poo is like a thick pudding consistency. The vet seems concerned yet. He is continually gaining weight, eats no problem, and is drinking peeing as normal. They aren't thrilled he was on raw, which I would love to get him back on it. They are thinking it could be colitis. Is it possible to have colitis on a raw diet? The vet wants to put him on Science Diet ID if it doesn't clear up. His body type is very lean, and he is very active. He does have a small spot of mange on his hip, which I managed to catch very early, so I am going to give him some sardines, vit. E and such to hopefully improve his immune system. Any ideas? I am wondering if I should worry about the "pudding poo" when he seems perfectly healthy, or is this something I should worry about? Mike says as long as he's eating, and is healthy, it could just be his type of poo at this point in his age. His brother has normal poos and is eating TOTW also. I know each dog is different. I really don't want him to have to take medications unless it is absolutely needed.
