How to Choose the Right Size
-
MUZZLE CIRCUMFERENCE: Measure the circumference of your dog's muzzle where you expect the goggle to land on their nose - usually around the back of their mouth.
-
HEAD CIRCUMFERENCE: Measure the head circumference where you expect the goggle to land on the forehead - typically an inch or so behind the eyes.
Size & Color
We offer two lenses with our goggles – one clear lens and one lens of your choice.
We do this for a few reasons, but mainly because the clear lens is great for training. We actually recommend starting to train your dog to wear Rex Specs with no lenses in the goggles. This allows your dog to get used to the frames first.
