I bought this product with a low expectation for my 13 yr old dog. About 8 yrs ago he had a stroke and could not walk. My friend and I nursed him back to health. Since then he had stiffness on one side. When the weather started changing this year he was totally mopeing. He would yelp and cry to get out of bed because of the arthritis on that one side. Since I've been giving him this product for a month now, he has never yelped. He actually jumps onto the sofa and he follows me around the house. Something he stopped doing. He did a total turn around. Within in the first few days he improved. I don't have any trouble giving it to him. he thinks it's a snack. Amazing product!! Gave me my dog back. I totally recommend this product!!!!
