Made with just one ingredient (hint: it’s in the name), the Savory Prime Cod Skin Treats have no added salt or filler, and they boast a healthy dose of omega-3s, which are beneficial for a dog’s coat, skin, heart, and immune system. When staff writer Mari Uyehara’s family got their Samoyed, Kaia, the breeder handed her off with a bag. These treats have been a high-value snack for Kaia ever since, outlasting other treat phases, and Mari’s given packs to other smitten dogs, too. The dehydrated squares are extra crunchy, so they’re best suited for active medium- and large-size dogs who can easily snap through them.
