Hello! My 14 year old cockapoo Biscuit (25 lbs) was just diagnosed with a large abdominal mass from an x-ray. We took him to the vet after we noticed him acting unusual for a couple days (little appetite, very tired, panting, black feces, etc...). They said there was mild fluid coming from the mass so we put him on Yunnan Baiyao to stop any bleeding. We also put him on a Turkey Tail supplement (Pet Wellbeing Immune Gold) and Nordic Naturals Fish Oil supplement for small dogs. Just a day later he already started eating again, huge appetite, walking around, no more blood in his poop, less panting, etc. I just ordered Vet Classic's CAS supplement as well which comes tomorrow. I have him on a high protein zero grain diet as of a couple days ago (NO kibble. I only feed him chicken, salmon, bone broth, beef, sweet potato, and a grain free "Just Food for Dogs" meal. I scheduled an appointment with vet specialists in at Cornell University Vet Specialists to discuss surgery and further treatment. Today he isn't doing as well as previous days. This is urgent as my generic vet told me he won't have much longer with us but I truly don't feel it's his time to go as just a week or two ago he was his normal self. I was wondering what your supplement suggestions are, diet suggestions, and how I can cure/help him. I really need all the help and suggestions I can get to help him get better fast! I'm willing to purchase anything to get him better. Let me know, thank you so much!
