A terrific protein source. Sardines contain appreciable amounts of the amino acid tryptophan as well as Omega-3 fatty acids and Vitamin B-12 (a hard-to-come-by B vitamin that is essential for cell function). A good source of selenium, calcium and phosphorus as well as Vitamin D, Vitamin B-3 (niacin) and Vitamin A in its preformed state, sardines are a great addition to any doggie diet. Pup Prep: Choose a low-sodium, water-packed variety and mash well, checking for and removing obvious bones, which can lodge in the esophagus or splinter and cause dangerous tears in the gut.
8. Wheat Grass
Also known as pet grass or cat grass. The young grass of the wheat plant (though it doesn’t have the same composition as wheat), it has chlorophyll, fiber, Vitamin E, phosphorus, magnesium, iron and potassium as well as some protein and carotenoids. Wheat grass is also purported to decrease constipation and help with upset stomachs. Pup Prep: Buy or grow a pot of wheat grass and make it available to your dog. Many dogs eat grass, and wheat grass is an improvement over the potentially herbicide-laden, contaminated grass growing along the curb.
9. Turnip Greens
Unfamiliar to many humans and dogs alike. Turnip greens are an excellent source of Vitamin K, Vitamin C, carotenoids, most B vitamins, fiber and manganese. They are also a good source of calcium, copper, potassium, magnesium and phosphorus, and provide a complement of antioxidants. A caveat: Turnip greens are bitter and contain appreciable amounts of oxalates that can bind minerals as well as goitrogens, which may interfere with thyroid function in susceptible individuals. Pup Prep: To minimize these effects and maximize palatability, sauté or blanch. Most recipes call for sautéing, which maintains the greens’ nutritional density and increases the odds that your dog (and you) will eat these healthful veggies.
10. Nutritional Yeast
Grown on mineral-enriched molasses and used as a food supplement. This inactive yeast is high in protein, B vitamins and chromium and several minerals as well. Protein is needed for muscle and cell growth, B vitamins are essential for energy metabolism and enzyme function, and chromium is important for insulin release and action, which allows carbohydrates and other fuels to be taken up by the cells and used or stored. Pup Prep: Don’t overdo it, as too much chromium can be detrimental. Use 1 teaspoon for a small dog, 2 tsp. for a medium dog and 1 tbsp. for a large dog. Mix it with food and introduce it slowly.
