Hello dogncatluvr and Kim. She believes Chip is somewhere around 17-20 years old, and is probably a terrier-chihuahua mix. He weighs 16 pounds. (She found him as a stray about 10 years ago). She is going to ask the vet about the medications you both mentioned, as well as the steroid shot. Hopefully, this will help and he can have some more good years. Thanks for help!
