My dog truly enjoys eating these. I can either mix them with his food or feed it to him like a treat. My grass loves them even more (which is really the point). Before, no matter where my dog peed, what his diet was, or how much water I put on the grass, there were always brown dead patches of grass that refused to grow back. After using these, we saw results within two weeks. Now we can't even tell where he's peeing and all of the dead patches are green again. This product has been a life saver!
