I’m trying to determine the proper size prong collar to order. Should I buy the 14-inch and add links, or go with the 18-inch and remove links to start?

Cindy,

I'm trying to determine the proper size prong collar to order for my 7 month old border collie and had one question. Based on your sizing instructions, he measures a snug 14 behind the ears; this is the size I'm ordering my dominant dog collar in. However, I'm not so sure about the correct prong collar. Should I buy the 14? and add links, or go with the 18? and remove links to start? Does the difference in thickness of the links make more sense to order the larger collar as the dog is still growing? I appreciate your time.

Thanks,
Colleen
