"I've tried a number of different joint supplements for my 16 year old dog who has had knee surgery and has advanced arthritis. In addition to the joint supplement she is on a daily torbugesic. I've tried many of the best supplements/vet recommended products including Cosequin, etc (I have been through 4 - 5 different kinds so far) and had seen only minimal improvements in her mobility. Since being on Grand, I have to say I'm sold. She's been on it for ONLY two weeks and already there is a night and day difference with her mobility, and her personality is MUCH improved - bouncing and cheerful again like her puppy days! For the first time since her lameness, I am hopeful to ween her off of the torbugesic! Definitely recommended!"
