Happy animals

I've heard it said that happiness can be contagious, so this week I'm going to put that theory to the test with a collection of happy animal photos. Take a look at the following happy animal photos, and then if the theory is true, hopefully they'll leave you feeling a little bit happier yourself.

1) Happy dog

I must admit I love ice cream, and eating it always makes me happy. However, it doesn't make me quite as happy as this extremely happy ice cream eating dog...

This is no exagerration to say that I don't think the dog could possibly look any more happy. I think he's right at the limit of dog happiness.
