I'm currently raising a Mal pup named Roust and I have had Black Belgians for years. The Belgian breeds are quirky and some go through some rough adolescent phases. They absolutely need proper early training and socialization to develop into great adult dogs. Approaching the early training and socialization in the wrong way can pretty much ruin some dogs. So far I have found Roust fairly easy and fun but I am a Belgian person
He settles well when nothing is going on on but at the first hint of action he's up leaping, spinning and sliding across the floors. He's very lovey and needs touched a lot. He's already 40lbs+ and he loves to sit in laps and be held (just be careful of his hard head hitting you in the face, he's nearly broken a couple noses :/ ). He is obsessed with being with me, out and about he barely pays attention to anything going on around him because he's so happy to be out doing stuff with me. IME his needy, dorky, lovey traits are fairly typical of male Belgians. It seems you either find those traits endearing or they drive you crazy LOL Roust is good in a crate to a point but when he thinks he's been in one too long, he lets you know. Even if it is 5am on Saturday He isn't wanting out because he has to potty. He wants out because...well because! This is fairly typical of a lot of Belgians I've had and known.
Roust is a "no touch" sort of dog with strangers though and you will find that in the breed. By "no touch" I mean he doesn't tolerate strangers petting him very well. I can take him anywhere, strangers can hold his leash while I walk away and he acts very appropriate but he doesn't want them to get too personal. He had a less than stellar upbringing until I got him at 14 weeks old (from the home his "breeder" placed him in...48 hours after the breeder placed him). He's come a long way socially since I first got him and I think he'll continue improving.
Not sure what you are looking for a dog for but there are a lot of very shady Mal breeders out there and unfortunately, some of them have a lot of credentials and accomplishments. If you are looking to buy a puppy from a breeder, look for a breeder who shares similar ideas with you in terms of how dogs are kept and interacted with. If you want a dog who's high drive, high energy but also a great companion, don't go to a breeder who's dogs live out their lives in kennels and only come out to be worked. If you are open to rescue, ABMC always has a lot of dogs available and they even get puppies in fairly often. If you're curious what a Mal would be like to live with, offer to be a foster home
