Debut ratings for FX’s “Terriers” were surprisingly tepid, averaging just 1.6 million viewers and 659,000 adults 18-49 — making it one of the lowest-rated FX bows in recent memory. That’s a little unexpected, given the strong reviews for “Terriers” and the amount of marketing put into the show.

One culprit might be the show’s title — and, perhaps the key marketing image (above), which put a terrier dog front and center (with series stars Donal Logue and Michael Raymond-James sitting far behind). Perhaps too many potential viewers figured the comedic drama, starring Logue and Raymond-James as unlicensed private eyes, was literally a show about dogs?

Either way, exec producer Shawn Ryan is still optimistic that “Terriers” can grow into a hit. He writes via Twitter (see below): “‘Terriers'” premiere ratings weren’t what we wanted, but good reviews and good Internet reaction gives hope for future. Tell friends to watch.”
