7. Pomeranian

 Pomeranians are cuddly little pillows. They need to be close to you as much as is reasonable and become frustrated and worried if you are gone for an extended period of time. Knowing when you should be at home and when you are running late, they are cunning. More difficult to prepare than some of the other items on this list are these tiny puppies. They are not friendly toward strangers and are prone to yapping while being underprepared from a young age.
