For whatever reason, most dogs absolutely loathe swallowing pills. But like us, they need their vitamins too – especially if you take them running or hiking. (And Flinstones chewables don’t seem to pack the same appeal.) Never stick your hand where it doesn’t belong again with K-10+ Dog Vitamins ($35/28-packet box). These odorless, tasteless powder packs come in four varieties: calcium, glucosamine, omega 3 and multi-vitamin formulas. Sprinkle a pack in Fido’s food or water, says founder Ryan Singer, and “they’re basically like Emergen-C for dogs.” About time.
