How to tell if a Teddy (Poodle) is purebred?

A purebred Teddy has a small, round head, almond-shaped eyes, a protruding but moderately long muzzle, and a slightly raised forehead. The ears are set far apart, hang naturally, the head is round, and the nose is black.

Also, a purebred Teddy has a curly coat in colors like red-brown, brown, gray, white, and black, with dense fur. Finally, the chest is broad and clearly relaxed.

The waist is short and wide, with a medium, well-proportioned build that is neither too long nor too short.
