How do you know their chosen because their fashionable? And by fashionable I taje it you mean because celebrities have them.
I know of two "celebrities" that have pugs, both now just over a year old
One chosen because he has three children so needed a dog that was good with children, and ful of energy yet as he works long hours was just as willing to settle and cuddle. He researched and researched, he even gave up a job that meant he'd spend many months out of the country.
Second brought with her brother, the parents of the celebrities partner own the dogs brother, again clearly researched. Their aware of how deep pressure is comforting to small dogs, never leave it for more than four hours. Their aware of pugs health problems breathing and weight.
both are thought of as almost children definitely part of the family. Wha t happens when they go out of fashion nothing dos well their family pets and you get attached to them celebrities aren't just going to go oh well I don't want the puppy I've loved for five years dos its breed isn't in fashion anymore.
I want a pug cross, not cos their cute or fashionable but because I love their personalities, I too have researched what I want and how suitable it would be for my circumstances.
