Fall catalogs are quickly cramming our mailbox and “Back to Cool” commercials are again making schoolchildren cringe, but the frizz-inducing weather reminds us with a humid slap each morning that it’s still summer. Celebrate the sweaty mess that is a D.C. summer at the Midcity Dog Days of August, a sidewalk sale and festival spanning the U and 14th Street NW corridors this Saturday and Sunday.

More than 50 businesses are participating in the sixth annual event, which corresponds with the D.C. tax holiday (spend less! get more!). Junction (1510 U St.) will feature refreshments, a gift certificate drawing, discounts on summer items, and 10 to 30 percent off everything in the store, including new fall items. Also, check out the new clothing store Destination U (1301 U St.) and the buy-one-get-one-free sale on vintage clothing at Meeps (1520 U St.) Or you can pretty up your pad with sales at home accessories and furniture stores like Sweet Magnolia (1534 U St.), Home Rule (1807 14th St.) and NU2U (1830 14th St.)

Shoppers whose favorite price is $Free.99 can take advantage of offers such as a complimentary class from Boundless Yoga (1522 U St.) on Saturday, cookies at Sparky’s (1720 14th St.) and a lemonade stand at Pulp (1803 14th St.).

The more canine inclined should stop at the Second Annual Midcity Dog Show on Saturday, where for a mere $10 you can enter your mutt in such, um, unconventional categories such as “most mysterious heritage” and “best in size.” Yes, best in size. Proceeds benefit the Washington Humane Society. And if this parade of pups so inspires you, WholeFoods (1440 P St.) is hosting a dog rescue adoption fair the same day. Are you planning to attend?
