Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to apply a horse tail bandage [title] Use only tools and products that are meant for your horse's tail. [step] Don't use products meant for humans, like human hair brushes. Use a wide-toothed horse comb to comb out your horse's tail and gently remove debris and knots.

Ending1: [substeps] You might even consider using only your fingers to detangle your horse's tail. Combing and brushing could cause hair to be pulled out, which could hinder the growth of your horse's tail. Ending2: Do not rub your horse's tail as you use these products. It will cause the bandage to undo and the bandage will get dirty. Ending3: [title] Clean the injured area with an ointment. [step] After removing any remaining debris, roll the injured injury over in your hand. Ending4: If your horse is already knotted, you might consider using a cut-off tail band instead. However, this is a medical emergency and is not a necessary part of the bonding process.
