“Hi there, two 900lb. horses – one with great feet, but will soon be turned out into a rocky paddock area daily, other horse has thin walled hooves / sensitivity (might not put her in paddock due to this).  Both have been on Horse Guard w/ grass hay min. 5 years.  Friend says give Hoof & Hair also.  Seems like too much biotin & other things.  Can you advise?”


Answer by Ph.D. Equine Nutritionist, Kelsey Johnson Nonella:

You have a couple of options. Hoof & Hair Guard is a great product to pair with Horse Guard, and you don’t need to worry about too much biotin and other nutrients. It will help your horse’s hooves and hair grow and look amazing.

However, I would recommend Horse Guard and Hoof Guard. It has 32 mg of biotin, zinc, methionine, and MSM (important to help build structural protein in the hoof).  Hoof Guard will help strengthen your horses’ feet, especially the one with thin walls. Horse Guard and Hoof Guard are a perfect combination, and should really help your horses’ feet, and prevent cracks from traveling up into the new hoof growth. Which would be good for your horse that you will be turning out.

It is important to remember that feeding a hoof supplement won’t change the hoof that already exists, but it will build stronger new hoof. So, as your horses’ feet grow the new material will be more resistance to cracks. The complete replacement of the hoof will take around 9-12 months.
