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.
I'd be very worried about a GI bleed. That's an awful lot of blood. Is this an older dog? Could be some kind of GI cancer. Parasites are apparently another common cause of blood in stool in dogs, but you say you've been deworming her. I'd probably take her to a 24 hour emergency vet or go first thing in the morning if I were you. Fuck, I don't know. I'm not a vet. Didn't you also just lose a dog? I hope this one is okay.
She's been to the vet once already and they said the next step would be ultra sound or x-rays. The dog is fine otherwise. She doesn't act sick at all but when she needs to go she goes and I've been doing a lot of cleaning up.
