My 13 year old mix(lab/dalmation/great dame) has had difficulty in the past with his legs giving out, they become stiff, and he falls easily. Since taking joint max 3, we have seen some improvement (65%). He doesnt fall as much, he walks up a flight of stairs in the presense of us at least two times a day, and he still can make it ontop of the couch with some hesitation. He has the legs of a 13 year old, but the mind of a 5 year old. We fear winter, and hope this product will hold him up as it has done for the past two years. I am sure there is something that would be better, but for now this is what I can afford financially, and it seems to have made an improvement. Hope this helps someone out, as some reviews dont seem to get detailed enough. Take care, and bless all furry our children!
