Trying to figure out if I am a Coton

My mom has always thought I was a Tibetan Terrier mix. She adopted me from a shelter so never really knew. That is what she was told I look like.
She saw pictures of her friend's Coton and he looks exactly like me. She was going to get a dna test and find out but they don't pick up on this breed. Some of you guys look EXACTLY like me. My hair even grows out like some of yours when my mom doesn't trim it. I am about 23 LBS. There are pictures on my dogster page, what do you guys think?
