My sister has 2 pomeranians. They are wonderful little dogs and very good with her 4 year old daughter. One is 10 and the other is 5. One thing you need to be sure to check is the breeder. One of my sisters Poms has an inherited skin condition that made him lose most of his beautiful coat. He has never regained it. But as far as upkeep they do have very thick coats but if you brush every day it helps tremendously, you can also clip them in the summer. My sister does and they love it.
I own a toy poodle and he is such a lap dog. Poodles are very intelligent and can be trained quite easily. I groom my own poodle, it is quite simple to do and saves me lots of money.
