I've only had my 5 yr old dog for two weeks & he's my very first pet, so I don't know all of his habits yet. He chomped a small piece of a drumette chicken bone off the street on Sunday night & hasn't passed it 36 hours later. He's eating & drinking (he's not a big eater in general), but seems extra sleepy & since last night, has no longer been hopping up to follow me around or go for a walk. Fed him canned pumpkin w/ the last 3 meals & now, instead of the regular poop he'd been having, he's only produced a few small droppings the past 2 walks. Is it a sign of blockage or from the pumpkin??
