Miamians have gone all in with juicing, cleansing, and organic everything, from toothpaste to body wash. So why do so many Magic City pet owners still tromp through the big chain pet stores, where garish cat and dog costumes and flimsy feather toys share space with the equivalent of McDonald's for dogs? Especially when the holistic pet product train has now pulled into the 305. Natural K-9 is full of all-natural, chemical-free food, treats, medicinals, and grooming materials for dogs and cats. OK, there aren't quite as many toys here, but the store's focus is the overall well-being of pets. That's why it carries raw food and everything from freeze-dried to grain-free to specialty, limited-ingredient brands such as Great Life dog food. You'll pay a little more — an eight-pound bag of Great Life's buffalo dog food runs $26.39, for instance, but it's made with real lean buffalo meat and a bucketful of other great ingredients like kelp and kale sprouts. The staff is friendly, hands-on, and incredibly knowledgeable, and if your pet has allergies or specific dietary needs, or is just fussy, they will weight the pros and cons of every brand to help you choose the best option. You've already realized how much that box full of organic produce makes you feel better; why condemn Fido to another bowl of GMO factory-farmed nonsense?
