OptiVizor Short Snout Sizing Guide

OptiVizor Short Snout Sizing Guide_Metric 


  • ONE SIZE DOESN’T FIT ALL: We often recommend customers order more than one OptiVizor to get the correct fit the first time. This is especially true when your dog is close to or is in between sizes. This will save you money on back-and-forth shipping and prevent any lag time in getting the correct size for your pet. You can return the NEW, Unused OptiVizor(s) for a product refund within 14 days.
  • PLAN FOR SUCCESS!: Preparing for scheduled eye surgery. Ideally, we recommend ordering the OptiVizor ahead of time to allow your dog time to get used it. When they do awake from surgery, they don’t think the OptiVizor is the cause of their eye discomfort as they have learned when they wear it they get praise and treats!


  • EXTRA FURRY HEAD AND FACE: A dog might have a large amount of fur around their face and eyes (i.e. Bichon Frise). In these instances, they may fit better in our Short Snout style vs. Regular Snout even though the Bichon is a regular snout dog.
  • OVERWEIGHT / EXCESS SKIN: A dog either overweight or with large amounts of excess skin (neck rolls of a Basset Hound) may need one size up from what the sizing chart says. It might be best to order more than one size to achieve the best fit the 1st time.
  • VERY TINY DOGS: (i.e. < 6lb. Chihuahua) which is a regular snout dog breed; most likely would need a smaller OptiVizor™ than we carry in a Regular Snout. Therefore, we often fit that tiny of a dog with one of our Short Snout OptiVizors that come in 3 smaller sizes than the Regular Snout version.
