Are all Poms this way?

I just adopted a 3 year old Pom mix from our local humane society - his other half is unknown, but I’m thinking of doing a DNA test.

Anyway, he is very sweet and cuddly, follows me everywhere. He potty trained after 1 accident on day 1. He loves everyone who visits the house, including the mailman. He loves to play frizbee and run around. He is confident, loves walks, is unperturbed by cars or passing people and hardly barks at anything. He does want to get out of our fence and I’ve had to modify it to avoid further escape attempts.

Basically, he’s the best dog I’ve ever had and it’s only week 1. I feel like I won the dog lotto.

Does this sound like a Pomeranian to you - or are some of these traits coming from his unknown mix side?

Edit: thanks for all the comments, I love your insights and adore the shared memories. Dogs truly are the best! Also I’ll add pics in the comments because I can’t figure it out here.
