Nothing is like a pit-bull-bulldog type dog. They have not just the aggression but the tenacity. The sheer will to hang on no matter what.
Malinois may be hyper but as even this story shows, a pregnant woman could stop him.
Don’t criticize the words; this is a Scandinavian story, so translation - even the usage - may be different.
As to this story, I would not be averse to putting down the dog.
I'm not sure what the mom did to get the dog off of her kid. What ever it was I'm glad it worked. I watched a kennel master pour a full coffee pot of scalding coffee on one to get it off of another dog. That dog let go in a hurry.
Malinois are not known to come off of an attack/bite easily. I've had many of them on a leash and have never been comfortable with them. I'll take a German shepherd or Belgian shepherd over a Malinois any day of the week.
