I have seen miracle results with glucosamine, Chondrotin and MSM Complex. My sister's yorkie, who is no longer with us, got so crippled up he couldn't go up or down steps and hardly walked or ran because of pain. She started him on glucosamine and I can't remember how long it took, but that dog came around and acted like a new puppy! Running and jumping and happy as could be!
My Libby has LP and it's at grade 2, and I don't want it to get any worse so I am giving her glucosamine...it is liquid and she loves it. I get it here:
