Yes French Bulldogs are pretty intelligent dogs and can be easily trained to do things you want them too.
French Bulldogs also make great family pets and companies but they're expensive to buy because of the cost of breeding them.
I wish I could afford a French Bulldog but they cost from $1,400.00 to $2,000.00 depending on where you buy the French Bulldog from.
French Bulldogs have a very great level of intelligence so if you're looking for a good dog that's easy to train then going with a French Bulldog is a good idea if you can afford the cost of the dog.
