Catch dog

A catch dog is a specially trained dog that is used to catch large animals in hunting, working livestock, and baiting.

In hunting, catch dogs work alongside bay dogs to corner prey and alert their handler by howling or baying. Catch dogs are typically equipped with chest armor to protect against the boar's tusk and neck armor to prevent neck injuries.

As livestock dogs, catch dogs use their weight and teeth to immobilize live animals so that they can be captured, or literally hogtied, by the dog's handlers, who may be stockmen, hunters, butchers, or farmers.
