A dog harness is a pieces of equipment designed to be worn by a dog around its body, typically around the chest and shoulders. It is a alternative to using a collar and leash for controlling and restraining a dog during walks or other activities.
A harness provides better control over your dog, especially if they tend to pull or have a strong build. It distributes the force more evenly across the body, reducing strain on the neck and throat, which can be particularly important for small breeds prone to respiratory issues. Comfort harness are generally more comfortable for dogs than traditional collars, as they don't put pressure on the neck.
