I think it's silly to group all herders that way. I mean, what does a Collie have in common with a Belgian other than basic shape? What does a BC have in common with an OES? There is a ton of variety in the group.
I see this a lot. Even people that own one type of herding breed are actively discouraged from getting a different breed. I hate to say it, but especially owning GSDs I get it from Malinois owners a lot. I couldn't POSSIBLY know what it's like to own a Mal because GSDs just "don't compare" and it's honestly quite f*cking offensive. I know what kind of dog I can handle, thanks.
I've never lived with a GSD, so I don't have a lot of direct experience. One thing that always stands out in my mind was a summer French Ring seminar. It was 100 degrees and miserable. The GSDs were sensible and laying quietly at their handler's feet or in their crates. The Malinois, however, were all spinning in their crates, or if leashed, up/down/up/down/spin/spin/down/spin, etc. It was scary because it was so hot. GSDs can certainly have a lot of drive an energy, but from what I've observed, they don't seem to lack in common sense and survival instinct that Malinois seem to.
This isn't anything new. I grew up with pit bulls and most people in the breed were ferociously protective of the breed. To be very honest I find pit bulls to be a generally breezy dog to own. They give so much pleasure it's hard to see the DA extra safety, the community caution, and so forth, as cons but that's not for everyone. Of course I also thought my pit bulls were high energy before my Malinois. Shamoo still puts most mals to a challenge as far as drive goes but she also seems content with hanging out sans stimuli, the Malinois are constantly looking for their next toy, game, trouble. That alone can set plenty on edge.
This. I grew up with tough, dog aggressive dogs. It was second nature to me. My APBT was easy, my AmStaf from performance breeding was more dog than my APBT, but still not difficult. Then I decided to get a Malinois. A guy in my club was an APBT guy that got into Malinois and kept telling me about how much more crazy they were. Whatever. The APBT that he still had wasn't from a line known for its ooomph. Then I got Harry, and I had to eat crow.
But then again, Harry and Stannis are two very different dogs. Honestly, I think that a dog like Stan would make a good starter Malinois. He's still a drivey, spastic idiot, so you still have to provide him with a lot of mental and physical outlets. But, he's quite social and non-reactive. I can take him anywhere like I do with Grant. We had our annual summer town festival last weekend, and I had Stan out at all of the events. He went to a children's carnival, a noisy/busy classic car and motorcycle show, then he was in the beer garden at a street dance with live music. None of it ruffled his feathers at all, except for an extremely aggressive husky that was being barely held back by an idiot that couldn't control it. Even then, all he did was hackle a little and look at the other dog like, "You need mental help," then he went on his way without a care in the world. I always said that the best dog in the world would have been Harry with Grant's stoic nature. I may have it in Stan.
