@NorwichMom whenever I see your boy, I do smile! Such a handsome chap.
OP - as NM says, it’s fads. Some of the most unhealthiest dogs, (Cavs excluded) are some of the most popular I.e Daschunds, Pugs, Frenchies. Lots of the breeds on the list are also perceived to be high maintenance in terms of grooming, so people swerve (then get a dog even higher maintenance).
And people can’t be bothered to wait. I’ve had people come to me asking to go on my wait list and one person even admitted that a Golden was their second choice - they actually wanted a field spaniel but didn’t want to wait years for a litter! For some of the lines more ready to ‘work’ and some of the ‘terrier’ breeds, the sad fact is that actually their purpose is no longer needed in today’s society. So they’re not being bought by the types of people they usually would and then people who wouldn’t have bought them anyway but might have been persuaded because they saw one out and about don’t see them so get something common.
A few years ago English Setters were really rare, but then a few went viral on TikTok (according to DDs) and suddenly they’ve increased in popularity. They’re still vulnerable but that’s more because supply can’t keep up with demand - at least around me. It’s one of my friends who breeds setters pet peeves - they don’t want the breed because of what it can do or it’s personality, or its history, they want it as a status symbol.
I have Goldens and although they’ve never been ‘vulnerable’ there has been an increase the last few years because of their popularity on TikTok. No recognition of the challenges of the breed or the health conditions. Just ‘oh but tucker and Todd are really cute. I’d love a Golden.’
It’s actually really sad. Some of the VNBs are some of the most well rounded, robust, personality stable dog breeds I know. But they’re not ‘sexy’ and don’t have a ‘teddy bear face’ so people don’t want them.
Edits for my abysmal spelling!
