I used to have a French Bulldog.  They are great companion dogs
French Bulldogs are so cute.  I think they are originated as a cross of bulldog ancestors from Paris and England.
I found that they are great with families that have kids and also really get along well with other dogs.
Yes they are great with big families, who can probably afford them since they go for around $3000 to $7000 usually.
Which makes it really bad that they have some serious health issues.  They cannot regulate their heat like most other dogs, so they can overheat easily
Yes the high costs of maintaining their health add to the overall cost, but they are great dogs.
They do require constant attention though because they can suffer from seperation anxiety after only a couple of hours
But despite all those drawbacks, they were the fourth most popular registered dog int he UK a few years back.
