Cannot compare a Boxer to a Bullmastif. Boxers are daft old things, best family pet you could have in my opinion as they just love kids and being involved.
Definitely in no way a guard dog. Alert you, yes, protect you, no. My old boxer would have just drooled on the burglar whilst trying her best to look scary (just looked cute really).
A Bullmastif though, is a guard dog and will protect its walker/family. Big bloody scary things.
EDIT: always late to the party![]()
You say that but labs aren't known for their guarding or protection abilities and especially not ours he's a great big dopey thing but there have been times when he's been taken out for a walk when we lived in a rough area and people have seen he's just a lab and thought they'd have a pop because he's not a brick outhouse of a mastiff and got a shock when he's started to go for them.
Whilst it's good he protected your home and partner it does raise some interesting questions.
Don't they put dogs down who attack people as once they get a taste for it they are likely to try it again?
This has been covered, by that thinking all Police and personal protection dogs would be dead after their first outing.
