Isis had a little fling at the dog park a few weeks ago. I forgot that I captured it with my cell phone.
A 6-month-old, very recently neutered Brittany spaniel named Charlie took a liking to her. He chased and chased her all over the park, and my girl can run.

When she'd stop, he'd roll over on his back and she'd lick his head.
It was the first time she spent more than just a few seconds with one dog. Clearly, this was true love.
Sadly, we haven't seen Charlie since then, although she's goaded other dogs into chasing her. Last week, a couple of them seemed a little snarly and Isis actually bared her teeth. For a little bit, she was running with her tail between her legs.
I grabbed her and asked her if she was still having fun (because she looked scared!) But she said she was fine, and trotted off and played with the growly dogs a while longer.
