Oh Julian, you are so lucky that your mommy was around!! That naughty dog could have been really nasty! It is like you said, your mommy is a hero!
At first, when reading your story, I thought there was a snake in your pen ...

Our bunny Billie loves to play in her pen too! As it is in the backside of our garden, we don't have to be scred for other animals!

here it is!
