Dogs often find themselves in dirty scenarios, from digging holes in the neighbor’s yard to burying tax documents. Clean your canine’s coat and conscience with today's Groupon: for $20, you get four self-service pet washes at Woodlands Pet Food & Treats, redeemable at the locations in Greenbrae and Mill Valley (a $60 value).

Woodlands’ easy-to-use, self-serve pet wash stations are equipped with safe, high-quality bathing supplies that allow dog owners to pamper their pooches with complete cleansing. Snag a pet-wash token for each canine and watch a demo that shows how to use the facility's amenities, such as the computer-controlled water temperature ($15). Wash stations stand at waist level, helping owners avoid back pain while maintaining eye contact with deferential faucets. Guests don rubberized aprons that deflect escaping water droplets before lathering their tail waggers with Earthbath natural pet shampoo—available in Mango Tango, Oatmeal and Aloe, and hypoallergenic scents. Freshly laundered towels and dryers greet dogs at the end of their soak, readying them for softest-hair competitions against sheep and Heidi Klum. When the bathing process concludes, staff members swoop in to clean stations for the next round of four-legged friends.

Those without a pup to polish can attend Woodlands Pet Food & Treats’ weekend adoption clinics in partnership with local animal rescue outfits in the region.
