As an owner of two dogs, I hate to see people using choke/prong collars for their dog.  Prong collars press sharp painful spikes to the dog's neck when they tug. Choke collars strain the dog's neck when they tug. We should not use pain for learning, Imagine if spikes pressed into your neck every time you made a mistake. It hurts the dogs neck and hurts it, It cause high stress and puncture to the neck. It causes less breathing,blue toung and more pain. It is basically abuse for dogs.We can stop stores from selling prong/choke collars. Please help Us change the collars.
