The Hungry Puppy is a proud carrier of Mustad Thrush Buster. Thrush Buster stomps out Thrush on contact. It creates a cleaner barrier, stopping dirt and manure from entering the frogs of your horse’s hooves. A single application relieves its agonizing, crippling effects and dramatically reduces chances of reinfection. It's so powerful it lasts for up to eight days without reapplication. Even in the wettest, muddiest terrain.
