Collar Sensitivity
Collar sensitivity is just like touch sensitivity but in this case, a dog reacts whenever someone holds his collar.
He developed this habit of snapping and biting on the hand which is trying to hold the collar because of the way humans behaved when he did the same for the first time.
When you hold the collar of your puppy, and you let him go if he protests then the puppy learns that he can get away from the hold whenever he protests.
Every instance of letting him go on his protest whenever you hold his collar is going to increase the intensity of his protest.
He will pull, use his paw, bark, yelp, or try to grab your hand as well. If he is a puppy then don’t let him go whenever he is in this protest state.
Only allow him to go when he is calm.
Practice this daily with your puppy, hold his collar, ask him to sit with you, and let him go after a period of time when he is calm.
This way you are going to teach him that calmness helps him to earn freedom.
This is a simple exercise with lots of applications.
You can calm him down by holding his collar whenever he gets into a state which is not expected.
Practice holding the collar daily and asking him to sit.
Do not let go if the dog is protesting.
Be calm and confident and quiet as well.
