German Shepherd dog

We feed our cutting horses rice bran....great for the coat. I do wonder what it would do for a GSD? I have one older male who always has a dry seeming coat, sheds a lot, just dull...give him fish oil and lots of other fatty additives, but he stays the same. The other six dogs have awesome coats.

I wonder how many others on here have horses and/or cutting horses... Kind of off track, but I've always been curious how many of us had GSDs and horses....

Horses are herbivores - dogs are carnivores.  Rice bran is appropriate for horses, so it benefits them appropriately.  Rice bran for dogs, while it may make their coats look better, it will negatively affect their digestive system as it will have to work harder to digest the inapproriate materials.  A healthy coat is achieved appropriately with a species appropriate diet and fish oil supplementation.  Nothing else is needed.

I use "coat boost" by CPN and it does contain stabilized rice bran as the second ingredient and my dogs have beautiful soft, shiny coats and no digestive problems.
