My dog produced this wonderful piece of art on my floor. Looks like there is some hot sauce in there. I gave her some Pepto to see if it helps. She's had diarrhea for several months now and has had de-wormer and antibiotics which haven't helped. I gave her some expensive prescription dog food for about a month and that may have help a little. I figure she has cancer or blockage of some sort. Thoughts? I need to take her in but x-rays and ultrasounds aren't cheap and they're just the start.
