Collar size

There is variation in the size of the collar. It is better to say diameter size of the collar instead of just size of the collar. There is big size collar for big dogs and small size collar for the small one. Choose what best suits your pet.

Hair of dog

The longer the dog’s hair is, the longer the prongs need. Because your dog’s hair affects the success rate of control. If the prongs are smaller and hair is longer, then it is possible that the prongs will not contact the skin of the dog. As a result, the shock will not work and your dog goes out of control.
