Kopertox is recommended as an aid in treating horses and ponies with thrush due to organisms susceptible to copper naphthenate. Thrush is a very common bacterial infection that occurs on the hoof of a horse, specifically in the region of the frog. The bacteria involved is Fusobacterium necrophorum, and occurs naturally in the animal's environment — especially in wet, muddy, or unsanitary conditions, such as an unclean stall — and grow best with low oxygen. Horses with deep clefts, or narrow or contracted heels are more at-risk to develop thrush. Horses with thrush, or those at risk for contracting it, are best kept in a dry, clean environment. Daily cleaning of the hooves also contributes to the prevention of thrush. 16 oz. bottle.

Instructions: Shake well before use. Clean the hoof thoroughly, removing debris and necrotic material prior to application of Kopertox. Apply daily to affected hoofs with a narrow paint brush (about 1") until fully healed. Caution: Do not allow runoff of excess Kopertox onto hair since contact with Kopertox may cause some hair loss. Do not contaminate feed.
