Vet Q & APuppy pulling: Is a harness or collar better to prevent neck injury?
I generally recommend using harnesses rather than collars for walking. If a dog pulls excessively on a collar, they can cause irritation to the trachea (windpipe) or develop neck pain or injury. Some harnesses, such as an EasyWalk harness or Gentle Leader, are designed to minimize pulling and can be quite helpful for training. Teaching Jasper a "look" command where he learns to watch you closely while on a leash is quite helpful. All of that said, I still like dogs to wear collars so that their identification tags are readily accessible in the off chance that they would run off. I hope this helps and that all goes well!
