Bulldog

The bulldog was a medium-sized breed of dog, characterized by its squat, muscular body and wrinkled face with a pushed-in nose.

Marjorie Dursley bred bulldogs and owned twelve herself. Her favourite, a male named Ripper, could not stand to be away from her, and thus she brought him along with her on visits to her brother's family at 4 Privet Drive.

Behind the scenes

 * On, Rowling revealed that she regretted making Marge a breeder of bulldogs, as she had come to know them to be a non-aggressive breed, and her sister owns one. She also noted that her sister owned a bulldog. However, she did note that they tend to look grumpy, and thus suited Marge.
