If they ever decide to add a new Pup to the PAW Patrol, I think it should be a girl Pup and her specialty is desert rescue.
We already have Zuma, who specializes in water rescue, Everest, in mountain or cold weather rescue, and Tracker, in jungle rescue.
As for her breed, maybe a Great Dane, a Border Collie, an Australian Cattle Dog, or maybe even a Pharaoh Hound!
Her vehicle could be a Dune Buggy or Sand Rail
Her Pup Pack could include an emergency shade like a parasol, solar-powered fan, sunscreen, a container of water, binoculars, or even a shovel to dig up sand, as well as a rope
Her Pup Tag symbol could be... a bright Sun or even a Saguaro Cactus
Her color could be... Orange like a Sunset, and her hat could be some kind of sun hat
