My human says I've been a playful great dane since I was little, I didn't believe her until I saw a couple of pics, one of them is this one.
To be honest I think I am a pain in the ass more than just playful, and this picture says it all. I'm only 3 months old here, at least according to my human, which is saying a lot.
I was a pain in the ass but at least back then I was an endurable pain in the ass, but now at my full size I'm almost invincible, playful or not, I can subyugate almost any dog, I just don't do it cause my human says I'm too nice and with a good heart, even against dogs who want to bite me or fight (lose) against me.
