can dogs get snowblindness?

That's very cool 

I trust you saw this tip on the Doggles web site...
"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."

Let us know how it goes.

Lara - what breed was your dog? I'm curious because multiple references I found noted that the effect varies a lot by breed, and though I watched for the sorts of signs you saw, I was kind of surprised my first season with my first dog to see none. My dogs were mixed breeds, with a fair does of northern snow dogs mixed in (though also some Shepard, which is one of the breeds fingered as being more prone). That said, now that doggles exist, I'll probably try some on the next healthy skiable dog I get (living with one former ski dog who can still do moderate hikes but no skis beyond pretty small and very firm stuff, and one young guy who drew a short straw on his hips despite his mixed breed - turns out to be great company for the old gal though...).

Ron - thanks for sharing the tips which make perfect sense once you read them. Distraction with good stuff is a valuable technique for many dog situations.

These look quite useful for people who like to let their dogs ride on motorcycles, in truck beds, or with their heads out the car windows (just try sticking your own head out on the highway and see how your eyes like it!).

Jim, the dog I traveled with at the time was also a mixed breed. He was a rottweiler, shepard, chow mix-very cute and hairy, but his eyes didn't like the glare. Good luck! Hope the shades work!
