“My dog Oscar,a 11 year old pitbull was in severe pain from arthritis, and would whimper in pain. I thought it was at that point where I was going to have to put him down if it continued. A friend of mine recommended K-9Rx for Dogs. Within days he was moving around with no pain. Fast forward a month later I’m yelling at him to stop jumping up on sofa. It’s like he’s 5 years younger. I recommend this product to every dog owner. Especially for senior dogs.
