Sizing tips

  • Measure
    Use a soft measuring tape around the widest part of your pup’s neck.
  • Check the fit
    The tape should be snug but comfortable, never tight. You should fit two fingers underneath.
  • Choose the right size
    Pick the size closest to your measurement. Between sizes? Size up.

✦ When in doubt, size up for extra comfort. Gemmies stretch to slip over the head, so a little room is a good thing.

Gemmies are a fashion accessory, not a restraint. Please don’t attach a leash or tags, and supervise your pup while wearing.

Not sure?

Send us your pup’s neck measurement and breed and we’ll recommend a size. Custom lengths from 5" to 35" are always available.
