If you’re concerned about your pets nutrition, consider that one of the most popular “SuperFoods” for humans right now bone broth. It can also make a great addition to your dog’s or pet’s diet. That’s right, bone broth for dogs can provide many of the same benefits to your dogs and other pets as it can for humans.
Why is Bone Broth healthy for dogs? Just like with humans, pets need to obtain certain nutrients from their diets in order to live long, vibrant lives. There are dozens of different nutrients found within bone broth, for example, amino acids like glycine, collagen, gelatin, and trace minerals like calcium, potassium and magnesium. Many of these nutrients can’t be obtained easily from other foods, especially highly processed dog and pet formulas that are made with hardly any real “food” at all.
Bone broth can be used to fill in gaps in your pet’s diet and help them deal with common health challenges, like joint aches, dehydration, diarrhea, an upset stomach and allergies.
