Yes, It all depends on the new owner how fast the dog will adapt, it does not matter puppy or x years old especially when you already had/have dogs. I would recommend a puppy when you never had or looked after any dog. If the dog is afraid/aggresive of someone or somebody it is of course easier to help them when they are a puppy, but eventually it is the same. You need to spend time with your Mallinois so you can become best friends.
