Micro hellspawns are created by behaviours such as picking up dogs during social interactions or to calm them. Also raising voice to tell the dog off for barking or being aggressive. But then also lack of socialisation and mental stimulation, especially since many small dog breeds are actually working dogs.

Basically exactly what to do if you want to train an aggressive, loud dog very rapidly. There’s no such things as an untrainable dog. If a dog is behaving that way, it’s doing exactly what it was trained to do by the owner’s poor handling and knowledge.
