Welcome Truman, and thanks for asking! (FYI: If you register as a member, your posts won't require moderartion.)

SynFlex glucosamine supplement was a primary part of Jerry's cancer care diet after his amputation. We believe it worked wonders for him, especially considering he had pretty creaky hips himself. SynFlex was formulated for people, and all they did to the pet version was add beef flavor. The link includes a complete breakdown of its ingredients and has much more detail.

For food, you want to stay away from grains. Find foods that have primarily meat and vegetables without unneccesary fillers. Jerry loved EVO – kibble and canned – on days when he didn't eat raw or get canned fish with his veggies.

For additional support getting around – on stairs and in vehicles, etc. – consider the Ruff Wear harness. And to help ease the pain of stiff joints after a long day hopping around on three legs, check out Bella's Hot/Cold Pain Relief Pack.
