Early Friday morning (4am) I woke up to Chevy going nuts in his crate (barking, crying) so I raced out of bed because he usually sleeps through the night. There was loose stool in his crate. I let him outside so I could clean up and I saw him squatting outside. I went out in the afternoon to clean up the yard and there were several small piles of loose stool. Yesterday (Saturday), we were out for a few hours and when we walked in the door, I knew Chevy had gone in his crate again. This time it was pretty much all over the crate (so much I just tossed the blanket that was in there, right into the trash) and there were a couple spots of what looked like it could have been blood. So he went out while I cleaned up. He seems to be acting normal, eating normal (Canidae ALS, 3 to 4 cups a day), but has been drinking a lot more water. He's never had loose stool before, they've all been formed and normal looking. I haven't been out this morning to investigate the yard or his poops. Could eating something he found in the yard be the cause? Should I take him into the vet? Or wait and see how he does today & tomorrow? Anyone have any idea what it could be or what I should do? I'm pretty much clueless when it comes to issues like these since we've never had to deal with them with any of our previous dogs. I'd really appreciate any advise. Thanks!
