It usually takes weeks to figure if a product will provide what it claims.I have not used them long enough to attest to its cognition abilities,however,I did notice that when I gave them to my large breed dog that her skin and coat were improving.We live in Texas which leaves my dog's skin on the dry side and I have noticed not nearly as much flaking as we typically see when brushing her out and her coat is nice and shiny.

My Dog loved these! is this okay for puppies under 6 months old also? I hope so I gave to my 5 month old pup and my 13 yr old dog. Same reaction, they loved them.

I like the tinier size. Perfect for training. I have 3 small dogs so these are perfect!
