Has anyone ever dealt with canine cancer? About 2 months ago my 13 year old mini schnauzer was diagnosed with anal sac carcinoma that had spread to his sub lumbar lymph node. Currently he is undergoing chemotherapy. After 2 treatments his tumor has reduced but the lymph node hasn't. This week he got another treatment with a different med, that will hopefully shrink the lymph node. I was just wondering if anyone had experience with this. When he goes into remmission I want to make sure it doesn't come back. I would like to find him a holistic doctor so he has the proper diet and supplments. At this point that isn't possible since we don't have enough money to pay our bills.
