If dogs truly are man's best friend, they're expensive companions. Between the food, the vet bills and the rent, owning a dog is a pricey commitment.

The rent?

That's right—in Pacific Heights, it costs more to rent a dog-friendly one-bedroom apartment than to rent a place that is strictly pet-free. According to data provided by Zumper, a rental listings website, renting a canine-friendly apartment in Pacific Heights will cost you $100 more than the median monthly rental price.

We discovered that for studio and one-bedroom listings in Pacific Heights, the median rent is $3,838; but, for apartments that allow dogs, that median price jumps to $3,938. To put that into perspective, the median price for pet-free rentals in Pacific Heights is $3,410.
