Bullmastiffs

To whomever searched for Bullmastiff's today and wants to know whether they are dangerous or not and what their temperment is: they are wonderful dogs and are generally sweet tempered but, like any dog (case in point the pit bull) they can become aggressive when trying to protect itself or it's family, when not treated properlyn or supervised (i.e. chained up in the backyard).

Mastiffs are commonly used on police forces and if you've ever seen Turner and Hooch, the latter was a French Mastiff.

I recommend meeting the dog you have in mind first and spending some quality time with her/him before making a decision. Make sure you see the dog in various circumstances such as outside on a leash, in a house, in a car, etc. Often people get a newly adopted dog home and forget that it can take anywhere from 1 week to 1 month for the dog(s) to feel comfortable in their new surroundings. Once you adopt that dog, you thus become fully responsible for it's care.

Think of them as kids who pay you with slobbery kisses and furry hugs ; ).
