Oh I know, Grace!... Either the collar is way too wide, or too restricting, or dishevels his fur, or disappears completely in his fur. D: Gah. I have yet to find one that I really like for him, besides rolled leather.
Fozzie, on the other hand, is perfect for any collar. My only dilemma with him is trying to make up my mind between a BILLION choices.
I think I'll only get smooth coated dogs, from now on. But I love the fluffiness too much!
