Pet E-Collar Size Chart

How to select the correct size e-collar for your pet? If your pet has used one from a veterinary clinic before, check with your vet. Otherwise, follow these steps:

  1. Measure Neck Circumference: Use your pet's regular collar to get the neck hole size. Ensure two fingers fit comfortably.
  2. Measure Cone Length: Measure from the neck to the nose. The cone height must be longer than this measurement to prevent licking.
