Pancreas tablets? Does he have EPI? If he has EPI, he will need to be on those tablets for the rest of his life. Pudding poops is one of a few symptoms of EPI.
Your dog is about 2 months older than mine...and I literally, 3 days ago, just started getting him down to pooping 2 times a day. So yeah, pooping 3 times at that age seems to be a little excessive. But every dog is different and their body clocks are different too. Maybe yours is taking a little longer to get down to 2 times a day. Again...if this has to do with EPI, you probably will have to be feeding more than the average dog, which means he will have to poop more. If he doesn't have EPI, we need to know why he's taking pancreas tablets.
