Usually he's a champion poop master and goes first thing in the morning, later on his walk after breakfast, sometimes a couple of times. I took him for a long walk yesterday in the early afternoon and he didn't poop which is very unusual and then this morning, lots of walking around, but nothing. As far as I could see, he didn't pee either. Otherwise he's perky, and right now, sitting on my foot as I type as he's confused why he's not getting his breakfast as per usual routine. I don't want to put more food in unless some comes out. He's not a great drinker, but when he does, he slurps a lot at a time. He drank as recently as last night. As I say, he's perky and was just racing through his commands with enthusiasm (another routine, we practice), and seems to want his food. Help? In the meantime, I think I'll give him a couple of spoonfuls of pumpkin.
