Hard to tell without seeing it. It could be him just trying to engage, perhaps with a bit of frustration added, or it could be that he is a bit more suspicious of people. I would make sure that the trainer is familiar with the breed and not someone that is going to try to fix something that is not broken… and potentially get things down a bad path. From the brief description it sounds like there is nothing terribly wrong. If the thought is that work is needed on the relationship, the recommendation typically more structure and a more regimented routine for the dog. If the thought is that the dog is over suspicious, the recommendation maybe to desensitize through controlled exposure to more socialization (“people watching” not “people engaging”). Again, hard to tell. Keep us posted!!

Thank you Ed,

I made sure that the trainer has experience with Malinois =)

We live in a big town, with a lot people around,cars, bikes, noises… Maybe he gets overwhelmed… Ive been working on his socialization (people watching/Positive reinforcement) but he is getting better so slowly, I think I am missing someting.
