A good idea is to make sure you can fit two – three fingers underneath the collar to assure proper width. As with very tiny dogs, such as a Chihuahua and collar never should be used, as it may cause strangulation when walking or leashed outside, instead use a harness.

Pet skin doctor reccomends checking your dogs collar periodically. A tight collar can cause hair loss under or around the collar. Also, it may lead to difficulty breathing.
