Hello, I am a new student and two days ago found out that our 6 yr old Doberman has lymphoma. diagnosed by taking a tissue sample from the small intestine where the mass is located.  so we have him on prednisone right now to try to shrink the tumor a bit and see if it helps with the diarrhea associated with the constriction of the small intestine.   I have some Colon Dire Era that I have been putting on his food (1tsp 2x per day). Giving him small meals and soft food . Any experience or advice is greatly appreciated.  The vet said he probably has a few months to live.
