Even if your dog is not a puller, he or she could be injured wearing a collar if they make a quick move to chase a squirrel, dog, or person. From a training perspective, dog harnesses are useful for teaching your dog not to pull as the pressure from a harness is more evenly distributed around your dogs body.This Front Range Dog Harness Vest eliminates pressure from your dogs neck preventing possible neck, spine, and windpipe injuries.Most Effective on Small and Medium Large DogsPreferred No Pull restraint. Small and Medium dogs lack the neck strength to handle a collar since it wraps around the animals neck. Additionally, because of the diminutive size of a smaller dogs windpipe, a collar is more likely to interfere with the dogs ability to breathe.Stronger Restraint during TravelOur Harness has a sturdy handle to secure your dog during car travel. It restrains your pet, keeping it from moving around the car or jumping out. Its design and location allows you to connect it to your seat belt. Also, a harness cannot choke a dog during travel, even if the device catches on another object.Supports Injured/Handicapped DogOur Harness provides greater support to an injured or handicapped canine than a collar. It supports your dog during walking, standing or climbing stairs. You can use it to aid the animal in these activities during recovery from an injury, especially when walking up stairs.Compare to other harnesses to see the Difference in our Quality and Appearance.
