Though dogs can take care of themselves, they choose not to—instead focusing their efforts on chasing squirrels, licking marmalade off babies, and learning American Sign Language. Give hard-working dogs the attention they deserve with this Groupon.

Pet Supplies Plus

Since 1988, Pet Supplies Plus has welcomed millions of furry critters of every stripe—from llamas and monkeys to potbellied pigs—into their animal-friendly stores. The shop is designed so that both pets and their owners can easily navigate the inventory of more than 10,000 items. Wide aisles give leashed pups enough room to roam, colorful signage keeps shoppers moving in the right direction, and low shelves allow dogs to sniff out their preferred brand of rawhide chew. A self-serve dog wash enables guests to scrub their canine companions' coats to a youthful, puppy-like shine, whereas grooming services enlist professionals to tackle tougher jobs, such as brushing out matted fur or convincing dalmatians to stop mixing white and black after Labor Day.
