Not allergic Training Dog Collar of Curogan, Herm Sprenger

Attention:

• Please measure the circumference of your dog's neck and head in the widest place. Compare neck and head sizes and add 1-2 inches to bigger size to determine an appropriate collar length.
• For Example: your dogs neck around 20 inches and head around (in the widest part) 22 inches. You should add 1-2 inches to bigger - head size in this case and choose 23 or 24 inches size collar.
• Never leave your dog unattended, when wearing a Metal Collar, because it may result in injuries.
• Please note, if your dog is not fully grown, you should order a Collar that will perfectly fit him. It shouldn't be bigger, because it will slip off his head and will be probably lost. It shouldn't be too tight as well.
