Come heel is a term often used in dog training to instruct a dog to come back and sit by their owner's heel. However, there are several synonyms that can be used interchangeably including: come back to me, return to my side, come to me, heel, and come sit. These phrases are often used when training dogs for obedience and manners, and they can also be used during sporting events such as dog agility and obedience competitions. Regardless of the phrase used, it is important to use consistent and clear commands so that dogs can easily understand and respond to their owner's instructions.
