Simple collars can be dangerous for dogs because they’re actually tightening on your dog’s sensitive throat that may lead to neck injuries. By wearing Raining Pet dog harness and leash set, this padded no pull dog harness doesn’t restrict around your dog’s airway and the pulling force is distributed around their chest and shoulders instead of the neck. It’s safer, stronger and more supportive than a standard collar. Raining Pet No Pull Dog Harness has plenty of adjustments, and getting on and off your dog is hassle-free with two simple buckles. It’s so comfortable with the padded and breathable material, your dog will love to wear it every day. All four straps are adjustable so you can create a custom fit for your dog. A snug fit is also so much safer because your dog can’t “escape” out of it. Please refer to the SIZE CHART carefully and measure your dog accurately before purchasing. If your dog is in between sizes we would recommend a size down for a snug fit unless he/she’s still growing and will eventually fill it out.
