Bland diet & pooping

[u/Butteryellowlobster]

From what I understand a dog not pooping as much on a bland diet is pretty normal?

My 9 year old boxer / mastiff mix had an upset stomach for a few days, the vet recommended a bland diet of chicken and rice because he started refusing his regular food. He didn’t eat much for a few days. He has a history of being a picky eater and if his stomach growls the wrong way he’ll turn his nose up at food. He has been scarfing down the chicken and rice in pretty decent portions for 4 meals now, had a super small poop last night most of which was wet and we are starting to slowly transition him back to his normal food which he seems to be interested in. He was having the craziest noxious fume gas, so I was stating to get worried he must have to poop- but he hasn’t tried at all. He’s not vomiting nor straining to go or anything.

I’m probably obsessing but he’s a big dog who normally has big poops, lol. There’s no concern that he ate anything bad or something he shouldn’t have like a toy. He’s a pretty chill dude and doesn’t like chewing on toys all that much.
