What is used to move an extremely aggressive dog to or from a cage or run?

Using a catchpole to move an extremely aggressive dog is the most appropriate choice due to several key reasons. A catchpole provides a safe and controlled method for handling a dog that may pose a risk to staff or others in the vicinity. It consists of a long pole with a loop at one end that can be placed over the dog's head, allowing for distance between the dog and the handler. This distance is crucial when dealing with aggressive animals, as it minimizes the chance of bites and allows the handler to maintain control.

The catchpole also enables the handler to secure the dog effectively while applying limited pressure, which can help calm the animal without causing harm. This is particularly important in situations where a dog is in distress or fear, as inappropriate restraint can exacerbate aggressive behavior.

In contrast, a leash might not provide the necessary distance or control needed for an aggressive dog and could potentially put the handler at risk. An animal carrier, while useful for transport, may not be practical when the dog is aggressive and unwilling to enter the carrier voluntarily. Using a collar alone can also be ineffective or dangerous, as it does not give the handler enough control to manage the dog’s behavior safely. Thus, a catchpole is the preferred tool in this scenario for safely moving
