St. Patrick’s Day is on a Sunday this year – two weeks from tomorrow – and that means an entire 3-day weekend of revelry at The Celtic Swell on Alki – featuring a costume contest for “Pets and Their People.” It’ll run 2-4 pm on Saturday, March 16th, per the announcement we received today:

Labs dressed-up like leprechauns! Shar peis with shillelaghs! Bulldogs boasting bagpipes! There’s no telling what you’ll see when Alki’s Celtic Swell Irish Pub hosts its first annual St. Patrick’s Day “Pets & Their People” Costume Contest featuring a free photo booth and prizes to benefit the Seattle Humane Society. The family-and-pet-friendly event is a must-do for everyone seeking festive and memorable St. Paddy’s Day fun.

Guests are invited to dress up their pets (and themselves) in St. Pat’s day garb, mug it up Irish-style in the Celtic Swell’s free photo booth, and win incredible prizes donated by some of the area’s favorite local businesses. Participation is free with all donations benefiting the Seattle Humane Society.

With two Siberian Huskies of his own, Celtic Swell owner Gareth Hughes says the costume contest and the cause felt like a natural fit for the Swell. “This year marks our 9th annual Paddy’s celebration, so we wanted to try something a little different! I can’t think of a better way to get the entire family in on the fun of St. Paddy’s day and give back to invaluable community organizations like the Seattle Humane Society who work tirelessly to promote positive change. Judging from the tremendous positive response we’ve received already, I’m confident this will become a cherished family tradition for years to come.”

Today’s announcement also includes a schedule of other events at Celtic Swell that weekend – see the full list here (PDF). The pub’s on Alki Avenue SW, just east of 61st SW, across from Statue of Liberty Plaza and Alki Bathhouse.
