So much to ponder here. Where to start, where to start ... OK. It's old news that "sexy" costumes are A Thing at Halloween, and that they are generally only sexy if you think porn star getups are sexy, and who knows? Maybe you do.
The real issue is the idea of sexy costumes for dogs. Until now I hadn't considered what words should never be used to describe dogs, but "sexy" would be in the top five, along with "delicious."
As for the costume selection, desperate-looking Chihuahuas are shown modeling as a bumblebee, Queen of Dogs, a rag puppy, Alice puppy, Candy Korn Witch puppy, and a pirate, posed coyly looking back over their shoulders. In the case of dog costumes, "sexy" appears to translate as "no pants." (Just like the human versions!)
If you really want to be disturbed, scroll down to the last costume on the first matching costumes page of Spoiled Rotten Doggies, which shows a Chihuahua dressed as a schoolgirl in a rather compromising position. (Is the Website safe for work? Depends if your workplace considers dogs sexy, I guess.)
