Protect your pet from annoying visitors with the Flys-Off Fly repellent ointment for dogs and horses. Because flies can be a big problem for dogs, especially in kennels or runs, this ointment works to keep flies away from open wounds, sores and other sensitive areas. It’s also great for equine pals, working to repel those annoying flies in the stable too. This works well for healing, as it prevents your animal from constantly swatting away flies from their wound or sore.
