I use the missing link plus (with glocusomine) and it's amazing. Their coats are wonderful, they are alot higher energy and my pugs allergies are much better and both of them shed much less, my aussie hardly sheds at all. Another product that I use on my dogs is called Prozyme, which is a plant based enzyme that helps absorb all the nutrients from their food and their supplements. Both are wonderful products for general health, they are said to hugely benefit arthritic, algergic animals and they are not too expensive at all.
