Hello Carol Ann, I had somewhat the same thing with my dog Annie, who died 3 weeks ago at the age of 15. She was almost paralyzed and was going to be put down about 5 years ago. She regained most of her mobility and this is what I did. I gave her bone broth in her food. Most times I made it, it was like gelatin in the fridge. I put in her food ( Taste of the Wild ) a bit of liver powder, vitamin E, some oil like olive oil or wheat germ oil. I would also give her some meat. She seemed to thrive on all this. I did give her Himilayan sea salt. Hoping and praying for Lucas’s full recovery

Mary
