On review aggregator website Rotten Tomatoes, the first season holds a 78% score, based on 41 reviews, with an average rating of 6.8/10. The website's critical consensus reads, "Wilfred is proudly vulgar and offensive, but a sentimental undertone lends the show some pleasing poignancy." The second season holds a score of 69%, based on 13 reviews, with an average rating of 7.4/10. The critical consensus reads, "Wilfred continues to be scaldingly funny with a deft humanistic touch but, like its titular character, it may be getting too coy with its narrative mind games." The third season holds an 86% score, with an average rating of 7.6/10, based on 14 reviews. The critical consensus reads, "Wilfred returns to a lackadaisical groove as its third season leans heavily on the combustible chemistry of Jason Gann and Elijah Wood, who both bring a hangdog charm." The fourth season holds a score of 100%, with an average rating of 7.8/10, based on 10 reviews. The critical consensus reads, "Wilfred rewards patient viewers with answers to its labyrinthine mythology during a final season that is harrowing, mind-bending, and ultimately moving."
Review aggregator website Metacritic gives Season 1 a weighted average score of 66 out of 100, based on reviews from 33 critics, indicating "generally favorable" reviews. Season 2 holds a score of 57 out of 100, based on five reviews, indicating "mixed or average" reviews.
Curt Wagner, writing in Redeye (The Chicago Tribune), said, "Stuffed with absurd situations and piles of bad taste, Wilfred is the strangest new show on TV. And the funniest."
David Wiegand of the San Francisco Chronicle wrote, "Wilfred works on many levels, something that may not become apparent until after you stop laughing."
Some of the less positive reviews included Mike Hale, who wrote in The New York Times, "Some shows aspire to cult status; this one goes straight there, practically bypassing the need to be broadcast at all," but concluded, "Gann's bits of doggie business ... are reliably humorous, but beyond that the show doesn't offer a lot of bark or bite."
Tom Gliatto of People magazine also gave a less positive review, calling the show "The Odd Couple redefined by psychosis and whimsy. I'm not wagging my tail."
The series premiere hit a positive note with viewers, and it became the highest-ranking debut sitcom in the history of FX Networks.

The second season aired from June 21 to September 20, 2012. On October 31, 2012, Wilfred was renewed for Season 3, which aired from June 20 to September 5, 2013.
