I assume a stool sample was checked? Obvious, but worth asking because you never know...Just ask your vet if there are tests that could be done such as they do on people with bloody stool. Ultrasounds, MRI, assorted scopes (endoscope, colonoscopy type scopes) dog could have ulcers, cancer, who knows? You can't just keep throwing meds and hope one works. The meds are probably cheaper though, the tests cost more. I didn't notice if she did blood work. I think people are saying that it might not actually be colitis.

Good luck, and don't worry your vet won't be insulted if you go elsewhere. Is it the $? You said your vet was treating for free. The free part might be influencing the frequency of visits....
