Well, not quite. I am not sure if anyone will remember us, but Mojo is my pitbull dachshund mix. I've had him for 2.5 years so he's about 4 - 5 years old now. He's usually healthy as an ox, although I worry a lot about him. Last night he was a bit more lethargic than usual, but since it was my bf's birthday, I was too pre-occupied and didn't pay attention. I went out as planned, leaving Mojo to keep my roommate company. When I came home this morning - not planned - I found our upper hallway with 1 large puddle of diarrhea, and 5 other spots of soft poo, diarrhea and something thick and foamy. I thought it was vomit but now I am not so sure... I cleaned everything up, apologized to my roommate (she grew up on a farm and was completely ok with everything). When I ran him outside he seemed a bit more himself. I kept an eye on him and took a nap with him. He slept normally, and when we went outside again he was much more perky, sniffing everywhere, and *seemed* okay. He even ate (a mixure of kibble and pumpkin) However, I can't find anything that he may have gotten into. There's no food that's been ripped into, or items torn up. I guess I'm a little worried that it's something else - except he seems fine temperment wise ... save he's still a little tired. Has anyone had a dog just spontaneously explode with diarrhea seemingly without reason? Should I go back to being my paranoid self and run him into the vet on the morrow? Or just keep an eye on him and stay on guard? Could it be parvo? He is vaccinated.
