Our 3 year old pup, Watson, was diagnosed with GI lymphoma around 7 months ago. After 5 months on the CCNU protocol, he was declared to be in complete remission. Watson has been on the same diet of high quality grain free dry food once a day, and raw 100% meat (variety of beef/chicken/organ mix) once a day. He has been on this diet his whole life, and never had GI issues, aside from the month or so before/during his diagnosis.
About a month ago, Watson presented with new symptoms - chronic diarrhea that is 100% liquid (although he had diarrhea during the lymphoma diagnosis, it was never quite this bad). He also has a lack of appetite and occasional vomiting. He was diagnosed with a functional ileus which was treated with prednisone/metronidazole/cerenia. Although he seemed to make a full recovery within a week of starting this treatment, unfortunately that is no longer working, the diarrhea and lack of appetite has returned, and he is extremely lethargic and uninterested in most activity. We've been able to "trick" him into eating by offering new varieties of foods he's never had before, but we are running out of options. He has been to the vet for multiple ultrasounds, bloodwork, etc. The lymphoma is not back, and everything else appears normal.
I know it's a long shot, but has anyone had anything similar with their B? We can't afford to keep going back to the vet for more ultrasounds just to be told that everything looks normal, but something is clearly wrong.
Thanks in advance!!
