91% of the dogs who had neck injuries had also been exposed to jerking and pulling on the lead by the owner or had been allowed to pull hard on the leash for long periods of time. Dr. Peter Dobias says in his article, “This gland gets severely traumatized whenever a dog pulls on the leash, The thyroid gland sits just in front of the trachea.
From a simple headache to glaucoma to a neck or spinal cord injury, neck trauma can also cause paralysis or other neurological problems. Stop these injuries BEFORE they start or get worse by using the NoChoke harness.
Dr Hallgren's study revealed that the dogs that “acted out” or in other words, exhibited over activity and aggression, 78% had spinal anomalies. Of those dogs who had spinal problems, 55% also had some form of problematic behavior.
Take a good hard look at the other harness on the market today (especially the ones that say they are “choke free” or “non-choking”) to specifically see how the force is transferred from the leash where you hold on, to the point of the stress that is placed onto your dog.
My guess. It's their neck.
I didn't want to get too technical here but if your dog is reacting in a negative manner i.e. choking or coughing then it is time to try something else.
Might I suggest a brand new NoChoke dog harness.
The safest way to walk your dog.
When your dog becomes unwilling to obey commands or respond to your hard jerks on his/her leash, maybe it is time to turn things around.
What I mean by that is, get a NoChoke harness and stop having to jerk on their leash to control them.
Take a good hard look at the other harness on the market today (especially the ones that say they are “choke free” or “non-choking”) to specifically see how the force is transferred from the leash where you hold on, to the point of stress placed onto your dog. It usually flows directly down the leash, across the top of the dog, straight to the front of the neck.
Don't just look at other harnesses that say they are "Non-Choking" or "Choke Free" make sure that you try them on in the store and have a friend call your dog from a distance. Look closely at where the pressure points are occurring on your dog.
Try holding the leash straight up and taught to see where the pressure is being applied against your dog using that manner. Imagine all directions that the dog may go and look closely at those pressure points also. More importantly, is your dog going to be comfortable & happy using that harness.
