Dog Days is cute.....I posted a review up in my journal about it - you can use the Good Readds link in my sidebar at the bottom to find it.

And that reminds me of some other series, both with male leads -- one is still newer....Unshapely Things by Mark De Franco (I think), but only one book out so far.

The Dresden Files books of course. Dresden can't keep a love interest for any length of time, much less capable of getting a triangle going.

And the series by Rob Thurman (Moonlight or Moonshine was the first one) - one brother has a vampire love interest, but no triangle; and the second brother has a love interest that is not quite off the ground.

But, yeah all male protagonists - I wonder if that is why there isn't a triangle?
