Your dog may need more than just a simple collar and leash to wear for a walk or an outing. They may need to use a harness as well. A harness helps with control and safety issues. Take these five reasons into consideration when you are deciding whether or not to purchase a harness for your dog.
Size of the Dog
Large or muscular dogs can be very strong. A harness can give you more control with your dog when you are out and about, even if your dog is not fully trained in good leash behavior.
Some smaller dog breeds may be more delicate and prone to injury. Wearing a harness disperses the pressure from one smaller area on the neck, to the back and the body. It spreads the stress over a larger surface area.
