So my partner and I got a dog recently and whooaaa man, the way women approach me just randomly out in the street makes me wish I'd had a dog when I was single. Instant opener + women feel safe to approach (obviously dog breed influences this). If you've got a friend with a dog, considering dogsitting and seeing your results. The dog doesn't help you flirt or anything, but it makes cold approaches just a fuckload more enjoyable... women just melt for a cute furry friend.
