Theo had his blood work done recently and his kidneys are still going down hill slowly. His thyroid is great. But the vet mentioned he is anemic. He said usually B-12 helps. I haven't had a chance to talk to him about how to give him b-12. Does anyone have any good options? Maybe something he could eat? He loves food. Monday he's getting some or all of his teeth pulled so i'm looking for something we can start adding to his diet after that. Any suggestions?
