What can happen if a tail bandage is left on overnight?

Leaving a tail bandage on overnight can indeed lead to circulation issues. When a bandage is applied, it restricts blood flow to the area it covers. If the bandage is too tight or left on for an extended period, it can prevent proper circulation, potentially resulting in swelling, tissue damage, or even necrosis in severe cases.

It's essential to ensure that any bandage applied to a horse is checked regularly and removed as soon as it is no longer needed to prevent these complications. Proper care and monitoring are crucial to maintaining the horse's health and well-being.
