Litter size: 6-8

The Bullmastiff is courageous, loyal, calm, and loving with those it knows. It has a very strong protective instinct and will defend its people against anything it perceives as a threat. However, it doesn't normally attack to protect, instead it simply knocks the intruder over with its massive size and pins them to the ground. Bullmastiffs become immensely attached to their families and do best when they can live inside with their people. Their protective instinct combined with their great size and natural wariness of strangers means that early socialization is a must. The Bullmastiff may or may not get along well with other dogs. Oftentimes, male bullmastiffs do not tolerate other males, regardless of breed. Occasionally, females are also intolerant of other females. The bullmastiff, in general, loves children and is very patient with them. Parental supervision should be maintained when they are with kids because these dogs are so big that they can accidentally hurt children while playing with them.
