Question about Glucosamine/Chondroitin

Interesting. I started our little dogs on Dasuquin a few weeks ago at the suggestion of someone on this board. It contains the glu/chon combo along with a couple other supplements. Our Rosie, 13 lbs, had knee surgery a few years ago and has a metal pin in place. She started exhibiting some discomfort and restricted movement with that knee. Today, I saw her stand on her hind legs to get a better look at whatever it was I was offering her. I realized she hadn't done that for a long time. Her blood levels must have accumulated to the point where the Dasuquin made a difference. Yay! Regular glu/chon combos caused her to get the runs so that's why the Dasuquin was recommended and it seems to be helpful in that regard.
