I have a 4.5 year old Rottweiler who is the ABSOLUTE LOVE OF MY LIFE! Of course she has a little bit of a hip issue. I have tried countless different products and spent way too much money to count, only to have her find anything and everything no matter how well hidden or disguised and spit it out! The girl knows! I put a cap full (Pot Roast) on her food in the morning and it didn’t even take a whole week before I noticed she wasn’t near as stiff as she had been! Bonus. . . it’s so easy for her to take. I’m pretty sure she thinks it’s some sort of treat! I’ve recommended this to a couple of my friends too and they’re now buying it for their critters!
