This P chain is relatively soft and not easy to catch hair. Dogs are more comfortable to wear. The connecting part is made of leather and is hand-stitched! In addition, a metal ring to control the tightness is added inside the P ring, which is very important! ! For disobedient dogs, you can put the metal ring small, but not too small so as not to hurt the dog's neck. Or a puppy who is using it for the first time or who is not sensible can relax a bit. Does not cause discomfort to the dog. .
