Got a couple of labs. Not as intimidating as your Malinois, but they’re each over 100 lbs and they’re good watchdogs.
I love the mals, they are totally safe with kids, but really tough protection dogs. The one female is what dog people would call civil, she is a true badass, yet curls up with a 4 year old, and often we wake up with her in bed with us. She is one that takes a pretty firm hand, she has at least three littermates that are military, and one is in a prison in Tenn or Ky I forget which.
