How can you tell a dog’s breed?

You can usually tell a dog’s breed by looks and behavior. First, large breeds like Labrador, Golden, Border Collie, Alaskan, Samoyed vs small Poodle, Corgi, Pomeranian, Bichon, Pug. Second, different breeds have distinct features—photograph and use image search to find matches.

Finally, for purebred proof, ask for a pedigree certificate or DNA test, or check the parents.
