American Bulldogs are happy, friendly and devoted pets that get along great with children, even those that are brought into the family later on in a Bulldogs life. However, because of they're size and love for constant stimulation, they are either best suited for older children (rather then babies or infants) or should be watched when around infants. The fear in this is not because of a possible attack or bite (this doesn't occur with Bulldogs) but because of their size and weight they could unintentionally role over or sit on an infant. However, believe it or not, you can actually train and American Bulldog to understand the difference between adult and infant with the right training, thus making him/her extra gentle around smaller children.

English bulldogs are very family friendly and generally get along with other dogs as well. Of course, like in all breeds, individuals differ greatly, but not all English Bulldogs are those lazy couch potatoes, uncapable of any type of exercise, with congenital. In general, English Bulldogs are actually highly intelligent dogs who want to play, cuddle, or have their fat little tummies rubbed, rather than learn some obedience trick.

The French Bulldog makes a very good companion dog. She is playful and fairly easy to care for, but she needs plenty of human attention. She is generally good around other pets and loves children.
