Skin and coat supplement

[Dr. Jeff]

A very experienced raw-feeding homeopathy devotee pet parent just reminded me of all of her pups' awesome skin and coat improvement when they used this product:

K9 Power Show Stopper | Dog Skin and Coat Supplement

I have no experiences with it, but the ingredients look great!

In general, how much consideration should be given to duplicating ingredients when adding a supplement? Thinking specifically of vitamins A, C, D, E, zinc, and selenium. How much is too much?

Thank you!
