What a handsome guy! From the first couple pics, I was going to guess golden or lab and shepherd, but in this picture:



His coat reminds me a lot of a rough collie's in texture, and his slender/delicate body shape reminds me of collie too in that photo. I saw that picture and immediately was reminded of my RB Willie. But he could just be a multiple mix of several breeds, hard to tell! He's gorgeous though and he looks well cared for, I'm betting someone lost their baby!
