My “senior” (9) Aussie/Kelpie has some skin pigmentation changes on his eye lids, and has always squinted in bright sunlight. I got some dog sunglasses (not actually Doggles brand) and while he is NOT a giant fan, I’m hopeful they will eventually be accepted.
If you’ve used them, how did you evaluate fit? We’re on day three and I find myself still making little adjustments to the fit. After today’s adjustment, the fit seemed to stay better for some frisbee tossing, so that’s a good sign. But I do almost wonder if he doesn’t need a larger size? The back of the head strap is adjusted out almost all the way, but the jaw strap is about halfway. And I worry that the outside edges are too close to the corner of his eyes.
