I love this product and believe that it is really helping my 13 y/o dog cope with walking issues - better than anything I've used to date. My dog isn't picky but she really likes these and considers them a treat so it's super easy to give them to her daily.  But I hate that the price springs from $82 to $130 - what is up with that?  If the price stays at $130 I will be looking around for something else because my large dog can run through a container fairly fast.  However, for a smaller dog, it might be worth it.
