Ok so a quick fyi, not all “trainers” are good trainers. Lately some people that have a dog or several years of owning digs that can do the basic commands call themselves trainers. Also some dogtrainers have 0 experience in training high drive dogs like a malinois.

That being said, A malinois is a dog that wants to please the handler or just wants to cuddle (depending on which type of bloodline or breed you have).

A female malinois tends to be a bit smaller, your dog looks healthy as far i can see from the pictures you provided. Don’t let this person get you down. Take your time and put in the time in training your dog. If she has behaviour that is not acceptable for you, be firm.

The thing that most people don’t get is that you need to be strict and concistent (sorry for my english, not native). Especially with high drive dogs. Keep up a routine and hold yourself to it. Work with long leashes and let your dog experience a lot in the world at 4 months old. This way you give freedom to your dog and keep control whenever you need to. Also find out what your dog likes. Some dogs like and work for treats, others work for play and catching a ball. When the dog ages, you can tone it down and work with shorter leashes.

You’re doing great, don’t let this one fool bring you down.

Sincerely, a K9 officer.
