Kopertox is a hoof dressing for horses and ponies. Kopertox is used to aid in treating horses and ponies with thrush (hoof infection). This infection can result in pain, puss or bleeding, and a smelly discharge. Thrush is caused by bacteria that live in muddy conditions and dirty stall bedding. Inactive horses and ponies that stay for long periods of time in their stalls are at risk for developing thrush. Kopertox has antifungal and antiseptic properties to help eliminate fungal infection and restore hoof health. Kopertox provides a water-resistant protection and does not require bandaging.
