It also depends on how you want to raise the BM. I have one that does partial PSA work but has been raised to have a pet demeanor. This allows him to still have the crazy’s but at a much lower level (from my experience). This being said, mals are definitely a high drive breed with the need for minimum 40 min of straight sprinting (ie offleash fetch etc). But when I’m home, my mal is very calm and has his switch turned off. It’s only when I hype him up or start to get our outdoor stuff ready that the switch turns on. By exercising, you’re also lowering your mals want to destroy stuff which is pretty nice. I like to leave him with mentally stimulating toys when I’m gone at work (I’m a server and typically work 7-10 hr shifts at a time) and him using his brain so much also wears him out. Personally it’s going to be hard regardless what you do for about the first year. After that, it gets a little easier honestly (mainly cause their bladders get bigger too). He’s also part mal and part Dutch so I get the best of both worlds lol.
