Dogs are supposedly man's best friends--unless the dog's name is Wilfred. And he is really a man in a dog costume. And he likes to mess with you.

The latest teaser for Season 2 of FX's comedy "Wilfred" shows Ryan (Elijah Wood) getting advice from both a devilish and angelic version of his canine cohort Wilfred (Jason Gann). You'd think they'd be making opposite arguments--but not on this series.

"Go on, Ryan, give 'em a lick," the Wilfreds tell Ryan as he brushes his teeth.

What do they think he should like? Um, it's a dog thing. Watch the clip above, along with several others teasers from FX. (Tramps and Fetch also are great.)

"Wilfred" returns for its second season at 9 p.m. June 28 on FX, and I can't wait. It's my No. 1 most anticipated summer series, to be honest. The first season was such a riot.

I guess I shouldn't say that Wilfred isn't Ryan's best friend, because he is. I mean, there's the stuffed Bear, but he/she seems to be friendlier to Wilfred than Ryan. You see, Ryan's a little messed up; he sees Wilfred not as a dog, but as a foul-mouthed Aussie in a dog suit who likes to smoke weed, pee on things and generally get Ryan into heaps of trouble.

But he's also teaching Ryan some valuable life lessons. And we could also use a friend like that, right?

Unless he's suggesting you "give 'em a lick."

What's your favorite teaser above? Are you excited for Wilfred's return?
