Dog lovers don't need a survey to tell us that we spend a lot of money on our pups. But exactly how big is our pet budget?

The ASPCA calculated basic annual expenses for a variety of pets [3] (not including one-time purchases, like a crate or leash). According to their survey, the average medium dog incurs the following costs per year:

Food - $118

Recurring Medical - $236.30

Toys/Treats - $55.60

License - $13.90

Health Insurance - $222.40

Miscellaneous - $41.70

I don't buy pet health insurance, but I know that I can easily spend over $400 on medical bills for one of my dogs in a year. And I definitely spend more than $118 per dog on food. Let's not even get started about agility classes and trials!

Personal money management website, Mint.com [3], also looked at pet spending through their users. They found that the average person in the United States spends $112 per month on their pets (note that this number is for all pets in a given household). They also looked at variation by city. San Francisco spent the most money, $148 per month over the national average.

Obviously, there are many things that influence these numbers, but it's a good start to get people thinking about pet related expenses before they add a dog to the family.

How much do you estimate that you spend on each of your dogs in one year?
