Health benefits of eating wheat for dogs

While the jury is still out on whether wheat and other grains belong in the canine diet, there's no mistaking that they're pretty efficient in transporting a range of essential nutrients into your pup's body. So, if you opt for a dog food containing grains, here are some of the micro and macronutrients your pooch could be benefitting from.

Firstly, let's talk about the big stuff (macronutrients). Wheat and other grains contain protein, fiber and carbohydrate, which is why they're preferable in so many popular dog foods. Your pup needs protein to grow and maintain healthy muscles, tendons, skin, hair, nails, ligaments and cartilage. Fiber is essential in maintaining the functioning of your pup's digestive system, while carbohydrates provide them with the energy they need to hop, skip and jump around the dog park. Fatty acids are also found in many grains which help to maintain heart health, skin, fur, immune system functioning and cognition. Wheat also contains a whole spectrum of minerals like manganese, phosphorus and selenium (just to name a few), which help with the growth of healthy bones and teeth, kidney and thyroid functioning.
