Here you can see the object of my 6 month old's obsession. Zen, our much loved, slightly coddled, sometimes grouchy 5 year old pug. He has weathered the changes in our family fairly well, but I think Isaac will give him a run for his money. At 6 months old, somehow our child is already able to chase the dog. During his waking hours, Isaac spends considerable time contemplating Zen and how to acheive reaching him.
