Doggy Jail

This is my current obsession.  Not this particular dog, but finding a dog to adopt for Christmas.  This little guy is named Lenny, and I just saw him on Petfinder this morning.  Is he the cutest thing ever?  I say obsession because when I decide to do something, it sort of consumes me.  Only the enjoyable things.  I'm sure my husband wishes that house cleaning consumed me, but alas, notsomuch.
On Saturday we met a sweet dog at Petco named Louie, a short fat rat terrier who wanted to play with my kids so badly he was going nuts.  When we went to the shelter to see him again, he was all over the place, and so hyper I didn't think I could manage him.  That same day I met Rudi, a gorgeous little Japanese Chin, who was mellow and delicate, and let me walk him around the yard---but what would my bruiser toddler do to delicate Rudi?  Another neighboring shelter has some puppies that just arrived, so I made myself read about life with a puppy to see if that is even something I can fathom right now.  I have been trolling Craigslist for dogs, and almost drove 2 hours away yesterday to rescue a gorgeous untrained golden retriever .
Why am I even contemplating another responsibility so badly right now?  It almost feels like a cosmic overthrowing of my better judgement. There is an animal that needs us this Christmas, and I need to find him.
