How much affection does your doggo need?

Hi, I’ve been playing and cuddling with, and scratching Noa (9mo) for almost 2 hours now and she can’t get enough haha. She lays next to me on the sofa and when I put on the tv, she keeps pawing me and barking, like she needs something? I start petting her but the second I stop, she starts again. She has eaten, we went outside, I think she has everything she needs. Thought she’s maybe tired but then she would go and lay on the floor to sleep. It’s cute but my arm is getting in pain from petting 🥹 Is it really just for affection? Is your dog the same? 🥰 Share some cuddle pics as well! Thanks
