I have a 21 yr old cockatiel and my oldest dog was 15 when we put him down, cancer. My cockatiel is old, cranky and wants to be left alone with my other bird, usually. He only gets excited for treats, everything else annoys him. My old boy, Fleetwood Mac/ FleeFly, was the best dog ever. Always loved to go with us everywhere, loved everyone and all animals, loved water-we had a great life with him.
