Research has shown that long hours in the sun without adequate eye protection increase the chances of developing eye disease. UV-absorbant sunglasses and sungoggles can help protect your eyes and the eyes of your pet from sun damage. For dogs with the increasingly common eye disease, Pannus, Doggles are proving themselves very useful. It is well known that dogs with Pannus should stay out of direct sun and get protection from UV light. Doggles are a great alternative for those dogs that can't stay inside during the day. Doggles also provide protection from wind and debris. Whether your dog rides in a sidecar, on a motorcycle, or in the back of a pickup, he/she needs eye protection.

Training  your dog to wear Doggles

Most dogs will readily accept Doggles after a short adjustment period. Training your dog to wear the goggles can be accomplished in a small amount of time if you follow these easy steps:

1) Don't put the goggles on your dog while indoors. Imagine yourself wearing dark tinted glasses inside. You cannot see, and neither can your dog.

2) When you first put the goggles on your dog, don't let him paw at the
glasses or roll to get them off. Reassure him that its okay. Take him immediately to bright sunlight and let him realize that he can see with them on. Walk around, get his mind off the goggles.

3) Try to go through this routine as often as possible. The number of training sessions required depends on your dog.
