I've been trying to get him to wear but he keeps them on for all of 2 seconds! I keep trying. We got a pair of Babiators x
Ours was the same but we found if we wore ours he was more likely to wear his. It took a few weeks but he will now keep them on without messing. Now he asks for them when we go out.
My LB wears sunglasses on sunny days. I got a small pair from MyLittleCoco at Boots last summer which he loves to wear now. Last year he wouldn't keep them on.
