Dog Personality

After dog-sitting for a few days, it's really obvious how I have the personality of dogs. 
In no particular order:

1. Dogs get super-excited about food.
2. Dogs love to take naps.
3. Dogs express their joy very enthusastically.
4. Dogs can go from enthusiastic to napping in seconds.
5. Dogs love to wander around outside.
6. Dogs love finding new things.
7. Dogs love going for a walk.
8. Dogs love to be cuddled and pet.
9. Dogs can be trained, but their humans have to be very, very patient.
10. Dogs love routine.

I decided to stop at ten similarities.  What are some others?
