We foster dogs and have had a few frenchies come through our door.
Out of 4 We had one that was fairly well built, could breathe okay (had the non flat nose) and was fairly healthy for the breed. She gives me hope theres a way back.
We have had 3 however that shocked me with how badly they were built as someone not used to the breed. Some you can hear there laboured breathing in the next room, since then i notice in videos many who are constantly "cutely" snuffling. We used to nickname ours pigs or gremlins due to it I mean im no breeder but surely being able to breathe is a start?
The constant snuffling, snorting means that they struggle to make non frenchie friends as not only are their faces hard to read for others but the sound like they are constantly growling.
The amount of care for skin folds is incredible, all 4 of ours came to use requiring fungal cream due to poor up keep. All but one had allergies and most digestive issues (hence the famed farts which are also made worse by their gulping of air during eating due to their face shape)
Other than the obvious boa sugery Our rescue spends lots on spinal surgery and cleft palates. I mean lots. Some of them are not built for life
Ignoring all the health issues, they are also a companion breed thats needy. I mean a watch you while you wee sort of needy. Sadly they are not built for the typical uk dog life of owners working for considerable amounts as they need a lot of love.
It always alarms me when people breed traits into dogs then are surprised when they require more care. In the same way you dont expect a working collie to be happy with a tootle up the road, and being left all day, a frenchie isnt going to do well with long periods alone
