Harnesses are usually the best choice for walking dogs because they don't put pressure on the neck. But collars are generally more comfortable. You should use a harness and not a collar if you have a dog prone to breathing issues (like a pug).
The harness provides safety and more control over your dog when you take them out for a walk & adds a little color to your pet, and it is very comfortable. It is simple to strap on with plastic clasps and easy to adjust to your dog's size. It is easy to adjust to the size of your dog's chest and stomach. Ultimate strength and resilience. Steel hoop to connect to the leash.
