Hi
I bought a pair of large Doggles a while back for our Dally to wear in the ute on long trips. She has but one eye and I wanted to protect it from wind and sun. After a while, a mirror check usually shows that they are above her eyes; I think they are pushed up when she gets into head around the side, nose into the wind mode, bumps them up on the vehicle. I quickly get tired of stopping to reposition and adjust and pop her in the front, with/ without the presence of human g/mother. Also, the attention she gets at the servos is quite unwelcome as she does not like the eyeballing, gets a bit of the 'plumber's mate' about her.
Actually don't think the fit is the best, they are perhaps a bit wide. Too lousy to try other brands though!
Good luck!
