Pomeranian questions

I have three female dogs, different breeds, ages, and personalities. The youngest is a Pomeranian who will be three this Autumn, the other two are a 9 year old Westie, and a 7 year old Yorkie.

The Pomeranian, Sofie, has some puzzling attributes, such as:

1. She likes to spend most of her time during the day by herself on the bed in my bedroom. It is very dark in there, so she spends lots of time alone and in the dark. She doesn't seem sad or lonely, but I wonder if that is normal or good for her. She will come out, mostly to see if there are any treats to be had and then back she goes.

2. She doesn't like to be cuddled or petted. She allows me to pet her in the morning, but becomes more skittish as the day goes on and will run to the end or the bed or jump off the avoid being petted. She doesn't seem afraid, just doesn't like to be cuddled or petted.

3. She is very bossy, especially with the older dog, who would make two of her. She won't allow her on the bed and growls and snarls at her. Once the Westie makes it onto the bed she seems ok with it.

4. If you try to pet her or hold her she draws her front legs up toward her chest in what looks as a frightened and submissive gesture. I generally then only pet her a very little, because she looks so miserable.

5. She loves treats and food much more that the other dogs and will snap and growl at them if they are in the same area with treats.

On the other hand she is very pretty, clean looking and smelling, and is the best jumper I've ever seen. She doesn't seem particularly afraid of anything, unless being cuddled and maybe I'm misreading this posture, I don't know.

The only other thing I would like to know, does anyone have any ideas, other than brushing to do something about the shedding? I could knit her a sweater from the fur I brush off her. The other two dogs don't shed, but she surely does. I'm afraid to bake or cook for anyone anymore because of the shed fur.

Thanks.
