Froggy loves his mask. It is part of the reason that he comes running when I come...because I switch out his masks. I have a stash of 12...yes 12....because he is very very very good at losing them. He does have 'goggles' around his eyes from rubbing his head on his Bovine BFF but he doesn't have runny eyes or bites on his face. Being around a herd of 50+ cows brings a lot of flies, a little hair rubbing is worth the protection it offers.
