A dog harness is like a vest that goes around a dog's body instead of just around their neck like a collar. It's a special piece of clothing that helps keep the dog safe and comfortable when they go for walks or do other activities.
The harness has a few different parts. There are straps that go around the dog's chest and back, and often there is a loop or ring on the top of the harness where you can attach a leash. Some harnesses also have padding or other features to make them more comfortable for the dog to wear.
The idea behind a dog harness is that it helps distribute the pressure of the leash across the dog's body, rather than just around their neck like a collar. This can be especially helpful for dogs that like to pull on their leash or have breathing problems.
When you put a harness on your dog, you want to make sure it fits snugly but not too tight. You should be able to fit two fingers between the harness and your dog's skin. It's also important to adjust the harness as needed so that it stays in place and doesn't rub or chafe your dog's skin.
Overall, a dog harness is a great tool for keeping your dog safe and comfortable when they go for walks or do other activities. It's a bit like a special piece of clothing that helps your dog do their best!
