The French Bulldog isn’t a good choice for a companion on a plane. As the Frenchie can’t regulate its temperature it can get very hot and encounter breathing difficulties.
The Frenchie may not bark very much but that doesn’t mean it won’t try and engage you in conversation. They make this noise that sounds something between a yip, yap, and a woof.
One of the reasons why they are becoming so popular with families in both the US and Europe is that they’re not only great with families and children, they’re also usually very good with other dogs.
