Have your dog in a relaxed position preferably standing up & place a measuring tape around the middle part of his/hers neck. Do not overtighten your measuring tape around the neck & leave space for 2 fingers to slide through . If you measure towards the head the collar will be too small & if you measure towards the lower parts of the neck the collar will be too big . If you do not have a measuring tape you can use a long piece of string instead & when you are finished place the piece of string next to a ruler to get the exact measurement. If for example your dog’s neck is at 25inches , this means the first hole of the collar will be at 25 inches ADD PHONE NUMBER TO ORDER NOTES Dogue De Bordeaux Leather Collar With Conchos & Rivets Studs, French Mastiff Soft Padding
