Review on 🐕 SuReady Stainless Steel Dog Prong Collar with Quick Release Snap Buckle for X-Large Dogs - Effective Choke Pinch Training Collar by Aretha May

There were no written instructions for installing one collar with teeth. It was my dog trainer who showed me where to place the spiked collar. It should be placed just behind the ears to avoid pinching the dog's breathing tube. The lack of instructions prompted me to place the collar around my dog's windpipe. This is not where I should have placed it because no dog owner wants to damage or damage the trachea. Also, my trainer told me that I should have chosen a collar based on neck size and not my dog's weight and build.
