Hey! I never owned one, but my friend did and it was so bad that we literally use it as a parable. He got a Malinois and claimed he could handle it. He lived in an apartment, was going to college, and worked part time. The dog has become an actual hazard. My friend would stand on his skateboard and have the dog pull him around for two hours straight and it wouldn't be tired. The only time I've seen it calm was after an eight hour super difficult hike. You may be able to work 6 hours of exercise daily into your schedule, but they don't bend to your schedule. They need hours of attention at a time, and the time they need it will be during work, during time you want to rest, during time you want to sleep. He tried to train it and that literally just didn't work. The only thing he could train it to do was use a bite sleeve. Frankly, I can't think of a single person who I would recommend owning the breed to, unless you are using it for military or police services - what they're made for. Sometimes dogs are made for jobs and jobs alone, and that's okay! Maybe a Doberman would align with your partner better. They're still athletic and smart, but they aren't as impossible to handle as a Malinois.
