 Again, I want to tell you about my Hugs and Kisses supplement because if you are sick and tired of your dog or cat's excessive shedding, if you want to make sure they're getting the best digestion they can possibly get, you want to make sure they're getting the Hugs and Kisses every day. In terms of their skin, it's a combination of lecithin and biotin that can't be beat to help prevent excessive shedding, dry skin, dander, hot spots, even hairballs.
