Do not be fooled by their size. Most of these dogs, especially when they are younger, are very active. And a lot of time, they are very protective. It is like they are not aware, that they are so small and they feel they are your guards.
Toy dog breeds are trainable. But as with all dogs, you must be firm and consistent. Which might be very hard for some people, because it can be hard to be firm on these little cute dogs with big eyes. But if you want dog, that will not be chewing, nipping etc, you will have to be patient, consistent and firm on them.
It is also advised to not over protect your dog! You will often time see small dogs that are afraid of everything. It is because their owners are over protecting them. It is a mistake. Its much better to act to them like to normal dog.
