If you're a dog, you'll never be self-conscious about your genitals and the world is your bathroom. You'll never have to squeeze into tight denim pants or small talk your gynecologist when she's knuckle-deep. Sure, you might live in a carpeted van with a convicted flasher, but as long as he lets you lick his face and keeps plenty of Snausage on hand, you're happy.
Besides the whole neutering thing, it really is a dog's life.
Having a hobby means you'll have something to talk about during your bus commute and your tri-annual pap smear. Going four-wheeling, chaperoning
field trips or making lanolin-based soap are all things you can do to
ensure you're a good conversationalist and therefore worthy of love.
Any hobby will do - just try not to talk about masturbation in mixed
company.
You should never leave the house without an umbrella and a healthy
mistrust of your fellow man. Only take things at face value if the face looks like it wants to steal your wallet or your innocence.
Wariness will get you through a lot of dangerous situations, like your
trip to the Middle East and your first official pelvic exam.
