Growing quickly in popularity following its official recognition by the American Kennel Club last year, the Toy Whifflea floppy-eared collapsed lung loosely attached to a severely twisted spinal columnis now one of the most sought-after designer dog breeds in the country, according to an AKC survey published Thursday. This hot new breed has everything pet lovers are looking for: the adorable teacup size; the cute little labored wheeze; the permanently prolapsed anus. When people see celebrities dragging them around on TV, its only natural theyd want one, said Toy Whiffle Association president Daisy Macnamara, who noted that since the breed neither requires nor has the physical ability to exercise, it makes a great apartment dog. You will need to take these dogs out at least twice a day for them to void the built-up fluids in their chest cavity. But given their lack of teeth or any musculature whatsoever, theyre extremely docile and great with childrenprovided, of course, the kids are gentle with the dogs super-cute, scrunched-up, and fully exposed intestines. Macnamara urged prospective owners to be aware that the popular breed suffers from a number of hereditary health issues, including eyeball dysplasia, spontaneous bone liquification, and a shorter-than-average 19-day lifespan.
