Frenchies are a cross between English bulldogs and pugs
While this is mostly true, some small bulldogs have been crossed with terriers. In this case, the French will have a longer snout, which will help overcome some breathing problems.
French women have litters naturally.
Due to their small bodies, 80% of the French are artificially inseminated. This in turn adds to the cost of the French from breeders as most dogs must have a Caesarean section. While the average litter is 2-3 puppies, the record number is 13, some of which we met at the London Frenchie Meetup at Regents Park.
