Sometimes clients at work who have some idea what a Malinois will say, "Oh, those dogs are really smart, right?" I usually just simplify to "yes". Blossom does do stuff that average people would be wowed by, usually to do with quickly grasping what I want and doing it eagerly, just because I asked. I think it's that hyper-biddability that makes them smart. And they are masters of patterns and subtle cues as well.
But truthfully those same traits can make her act kinda dumb. When I pack her crate up for any reason, if I tell her "kennel" she will run to the empty space where it was and jump just like she's hopping through the door that's not there, LOL. Keeva would run to where the crate should be, find nothing, look around for another crate, and then probably bark at me and offer some other behaviors.
I put slippers on the other day, and she was all, "YOU PUT SHOES ON AND SHOES MEAN WE GO OUTSIDE AAAAAAHHHHH" and it took her like 20 minutes to accept that we weren't going outside. If Keeva is crated and I let her out, Blossom also thinks, "OMG TIME TO GO OUTSIDE. I BETTER SPIN AND CRY!" because I guess she associates dogs being let out of crates meaning we go outside, probably because that's what happens when I get home from work.
The intelligence of more primitive breeds is very different IME. Keeva definitely has a streak of that in her - she's a thinker. Well sometimes, she definitely has her obsessive herding breed times too.
Blossom is more trainable, but I would absolutely call Keeva the "smarter" dog.
