BarQuee at Marquee Join pooch host Spartacus as the Cosmo club celebrates the fifth anniversary of Noah’s Animal House with a party for pups (25 pounds or less).

Ghostbar Dayclub Launch The daytime debauch-fest went into hibernation for the summer, finding a home at the hotel’s casino tables during the sweltering months. It returns this Saturday, and you can expect the same bottle-popping, piñata-smashing, whistle-blowing, beer-bong-chugging action that made it a favorite the first time around. October 20, 1 p.m., $20, local ladies free.

The Pink Party at Blue Martini The Town Square watering hole’s signature color takes a back seat Saturday night, when it presents a Pinktober party benefiting the Nevada Cancer Institute. Ladies can enter to win a girls weekend getaway in Arizona, but everyone can enjoy the drink specials (Stoli elit, One Hope Chardonnay and Blue’s Pink Passion martini) and live music provided by Smasht. October 20, 8 p.m., $20 men, $10 local men after 10:30 p.m., ladies free.

A Time for Pink with Jessica Stroup at Pure Although the brunette beauty has acted in a number of recent horror films, she’s most memorable as Erin Silver on the CW’s 90210. Stroup celebrates her birthday on Saturday, which doubles as a celebration for Breast Cancer Awareness Month (proceeds benefit Susan G. Komen for the Cure and the American Cancer Society). October 20, doors at 10 p.m., $30 men, $20 women, ladies free until midnight.

The Wanted at 1 Oak The band will be “Glad You Came” to the Mirage venue Saturday night as they take the club’s stage to perform. Who knows—maybe you’ll get caught up in the beats and end up “Chasing the Sun” ... October 20, doors at 10:30 p.m., $50 men, $30 women.

Psy at Rehab Good news: You still have time to learn the dance for “Gangnam Style” before the Korean pop star performs his hit at the Hard Rock Hotel on Sunday. Bad news: You’re still going to look like a complete fool doing it. DJs Eric D-Lux and Shift also supply sound for Rehab’s season closer. October 21, 10 a.m., $40 men, $20 women.

Neon Circus at Hyde Run away and join the circus Sunday night, as the lakeside Bellagio club turns into a Big Top for the return of its XIV Vegas Sessions.

October 21, 5 p.m., $30 men, $20 women.

Wolfgang Gartner at XS The electro DJ returns for his Encore residency, bringing his Love & War tour to the expansive indoor/outdoor club. October 21, doors at 10 p.m., $30 men, $20 women.
