The two main types of dog handling equipment for a dog owner are the leash and collar, and the leash and harness. Each of these tools have their pros and cons from the standpoint of a pet owner, of which we’ve laid out a few for each:
Collars;
Leashes can be attached to both leashes and harnesses with relative ease, so that doesn’t really come into the equation. Where it does come into is what happens once the leash has been removed; a harness will continue to restrict movement, whereas a collar can sit more comfortably on a dog’s neck.
When the leash is still attached to the collar, dogs can often pull against the leash and hurt themselves through choking, as most dog owners will have experienced.
Harnesses;
Harnesses have a lot of advantages over a collar, as they can provide far greater control over your pet and do so more safely for their health as well. This is particularly important for larger dogs that can potentially overpower their owners.
