Ha, yep, my portrait shots have increased exponentially since having kids. It's generally easier (and often better!) to photograph their faces than it is a landscape.
I love having them...don't get me wrong. When I posted earlier, I'd had an entire day of constant whines, cries and whinges and I reminiced for a moment of when I shot landscapes often in the peace. But I wouldn't change it for the world.
As for a dog - I used to have three! I took them out with me on my adventures. Unfortunately, they have all since died. The attached was the last to go - my 16 year old cross-lab\setter. Died in the summer :-(
