"Collie Nose" gets bandied around a lot to refer to hair loss and inflammation around the nose, but not all hair loss and inflammation around the nose is Collie Nose.
Besides bacterial problems, plastic can cause an allergic reaction that looks similar to Collie Nose, depending on the dog and/or the plastic. I once had a dog who would react to a particular plastic crate in a way that looked scarily like Collie Nose (I feed my dogs in their crates). Needless to say, he was switched with someone in a wire crate! Problem gone.
It's also important to note that pigmentation isn't always an indication that the dog is safe from the sun. I had to treat a rough collie rescue with no white on her muzzle for sun-induced sores once. I haven't heard from her new owners as to whether a diagnosis was obtained, but I suspect she had something more serious than simple solar dermatitis.
