What could make a dogs poop look like this?

My puppy we're still working on house training, pooped in the house and I noticed it looked strange. She normally has solid poop but it was a little squishy and yellowish and the look of it was like ground beef. When I grabbed it with a paper towel it squished and there was one little part that looked like blood,not even as large as a dime. Earlier her mouth was bleeding from a rawhide.
