Oh, I see blood in Skye's stool, that's not good. She could have parvovirus if she isn't fully vaccinated, she may have eaten something rotten, she could have a GI illness, a foreign body, or she could have intestinal worms. I'd have her checked out by a vet first thing in the morning. Best of luck.

    Hello, thank you for using Petco Pet Education Center, formerly Petcoach. The most common reason for a puppy to have bloody stool would be intestinal parasites (worms). I suggest you take Mini to your vet for an exam and fecal test to check for parasites. That way she can get the proper treatment. Hope this helps. Best wishes.
