Alright, this is definitely one of the more "weirder" things that I've asked here LOL
So Murph had another bout of diarrhea about 3 weeks ago. As usual, called the vet, prescribed antibiotics, he was better in a day or so. The vet also recommended that we start using the Flora a few days after the end of the antibiotics.
I was giving him the Flora about 2x-3x a week with one of his meals (usually dinner). However, last Saturday, I took him out in the afternoon and he had to go...well...you know. He took his normal stance and started. For some reason, when the first log was halfway out, he started yelping (like the painful yelp). He was trying to see what was coming out, but I guess the pain passed. He finished up normally and we came back inside. Sunday morning, he went out after breakfast to do the same thing. First log he yelped like crazy, but then he finished normally.
I have no idea what even happened. My first thought was maybe he didn't drink enough water which made it harder to pass or he ate a stick/woodchip/something pointy that hurt coming out. I searched through the pile on Saturday and didn't see anything that would cause any pain. As of Sunday's incident, we've stopped using the Flora. He's been fine ever since Sunday morning (running, playing, eating/drinking, going normally, etc.). I also tried to look at his "poop chute" to see if he was bleeding or anything and he wasn't (both times).
Has anyone else ever experienced something like this? He's never had a problem with the Flora before, so I'm thinking it was a stick or not enough water. He has a vet appt for next Saturday, so I'll definitely bring this up when we're there.
