The Staffordshire Bull Terrier, AKA the Staffie, AKA the 'nanny dog'. These guys get bad press when they're just a little house hippo! The Staffie got the name 'the nanny dog' due to being an amazing family dog and incredibly sweet with kiddos. Unfortunately, you are very likely to get injured by their overly-excitable wiggly butts and tails constantly whipping around your legs! Calm down doggos, we love you too!
