I've had ten Frenchies, as well as Dobie, lab, Dulux dog, poodles, Irish setter, cavalier, Cocker, border collie - all Rescue dogs .
Yes, Frenchies come with health issues, but so do all breeds.
There's a massive trade in puppy farming and imported dogs: reputable responsible breeders will test parents for BOAS, luxating patella etc and will not breed from affected dogs.
They don't let the bitches have too many litters ; they don't keep the dogs outside in sheds. This is expensive, and is reflected in the price.
If you see a Frenchy for less than a grand, you can bet its parents haven’t been selected for good health, and the pup's likely to have problems:
Eg £700 bargain needs a £2,500 surgery for BOAS surgery, for example.
Importers and backyard breeders are very skilled at hoodwinking punters: they advertise as UK bred, they let you meet the (fake) dam/sire, they give you all the "right" answers. They even sell dogs that turn out to be crosses: mixed with chihuahua, staffy, Pug, anything.
They exist because people want cheap puppies and they want them now. If you're dead set on a Frenchy, I'd say :
- don't buy an import
- don't buy cheap
- buy from someone who's been in the breeding game for years, not from Mrs Get-rich-quick
- prepare to wait, and to travel
- read as much as you can about the breed (real books, not Facebook, and goggle "BAOS/BOAS)
- consider fostering first, to get experience of the breed
- consider adoption:

F. Bulldog Rescue GB
are two Rescues, and there'll be similar for pugs
