Let the Westminster Dog Show parade its purebreds: We prefer underdogs — schnoodles and goldendoodles, cockapoos and cavachons, and even plain old mutts — and we know many of you do, too. Prove it! Send us a color photo of the non-purebred dog in your life, along with your pet’s name and age, “pedigree”— the breeds it’s made up of — and a line or two about what makes him or her a winner.We’ll also need your name and neighborhood,with a high-res jpeg of your pooch. We’ll run our favorites the weekend of Feb. 8, but we need to hear from you before midnight Feb. 4. So get scratching! Contact us at underdogs@nypost.com.
