Here's a little dating advice.  If you're not a dog person, and you're thinking about dating a women with a dog . . . don't bother.

According to a new study from LiveScience out of the University of Houston, a huge key to a good relationship is when the man loves the woman's pet as much as she does.

The effect doesn't happen when the genders are reversed.  If a man has a pet and the woman doesn't love it . . . there's really no impact on the relationship.

The researchers say it's because women, quote, "are much more in-tune with the harmony of the household."  In other words, they want everyone to get along.

There's one caveat to this.  You should love a woman's dog . . . but not too much.  When women believed their men loved a dog more than them, it led to jealousy instead of relationship satisfaction.
