What is the recommended method for properly restraining an animal?

Using a headgate is the recommended method for properly restraining an animal, particularly in larger livestock like cattle. A headgate is a device designed to hold the animal's head in place, which prevents sudden movements and allows the handler to examine or treat the animal safely. This method provides the handler with better control over the animal while minimizing stress and injury to both the animal and the person handling it.

In contrast, using a leash is more appropriate for smaller pets and may not provide sufficient control for larger animals. Holding an animal tightly can lead to injury for both the person and the animal as it may cause panic and resistance. Using a blanket can be helpful in calming an animal or providing a visual barrier, but it is not a reliable method for restraint on its own. Thus, the headgate is the most effective and safe option for ensuring proper restraint in veterinary or handling situations.
