Season Premiere: Get ready to howl, because FX's twisted canine comedy is fetching a third season tonight. Elijah Wood is back as Ryan, a suburban loner who sees his neighbor's dog Wilfred (Jason Gann) as a cursing, pot-smoking dude in a dog suit. Season 3 kicks off with a double-dog dose of episodes, including one where Ryan becomes friends with his mailman (Zachary Knighton from "Happy Endings") — a friendship that makes Wilfred go, well, postal.

Season Finale: Uh-oh… looks like Will Graham may have finally caught on that his therapist Dr. Lecter is a cold-blooded killer on tonight's freshman finale. But the authorities would rather slap the cuffs on Will after evidence points to him being the Copy Cat Killer. Evading the cops, Will forces the doc to clear his name at gunpoint. Dr. Lecter doesn't look very scared, though, does he?

Looks like the gang is getting back together: Sam and Jesse jet down to the Dominican Republic tonight to join Michael and his rogue former employer Burke ("Heroes" alum Adrian Pasdar) with a down and dirty mission that quickly spins out of control. Plus, Fiona helps Michael's mom Madeline fend off a bookie looking to collect an unpaid debt.

We're getting down to the nitty-gritty tonight in Gordon Ramsay's "Kitchen," with the five remaining chefs earning the coveted black jackets and getting an emotional visit from their family members. (What is this, "Survivor"? It's not like they're stuck on a deserted island or anything.) Tonight's challenge winner gets to enjoy a nice sit-down meal with their family, while the losers are stuck on recycling duty.

The Rock and his tatted-up guns have a new challenge for the "Hero" contestants tonight: Make your way through the Panamanian forest, and handle huge snakes along the way. (Yeah, we'd be gracefully bowing out at this point.) Plus, one contestant has to climb to the top of a towering bridge, while trust issues plague the group in the War Room.

Life on the swamp might seem nice and laid-back… but not when the days are ticking away on gator season. These swampers face unexpected obstacles tonight, including one veteran hunter who's forced to set his work aside when a family member gets in trouble. Plus, another team closes in on a legendary gator they've been tracking for twenty years. Oh, is it "Supergator"? We saw that Syfy movie; it was awesome.
