I have been a fan of this brand since they launched and relaunched - so happy to get it on a subscription model To say that it has helped with my 15 year old Golden's mobility is an understatement..I think it's one of the primary reasons he still moves AND comes upstairs at night. It's becomes an importnat part of the daily routine with my five big dogs' routines - to help with a variety of things - anxiety, mobility, general well being. I'm such a mega fan I recommend this to every dog owner and lover I can!
