6 Food High in Magnesium for Dogs: Vet-Reviewed Facts & FAQ

Like humans, dogs require essential minerals and vitamins to function. Magnesium, along with calcium, phosphorus, and potassium, is an essential macromineral. It’s important for bone formation, muscle, and nerve function. Magnesium must be included in the diet in sufficient amounts to avoid deficiencies. Commercially available complete dog foods contain enough magnesium for healthy dogs. A lack of magnesium in a dog’s diet can occur for various reasons, including chronic diarrhea, kidney failure, and diabetes.

This article examines magnesium-rich foods. However, not all of these foods are suitable for all dogs, depending on their age and health condition. Always speak to a vet before adding additional foods to your dog’s diet, especially if your dog is showing any signs of illness.

Top 6 Magnesium-Rich Food Sources for Dogs

1. Fish

You can select a fresh, boneless fish fillet, but check it for tiny bones before cooking it. Then, you can grill, poach, bake, or steam it without oil, pepper, salt, or onions and garlic¹, which are toxic to dogs². The fish’s fins, head, bones, tail, and scales shouldn’t be included because they pose a choking hazard and risk damage to the gastrointestinal tract.

It is important to avoid feeding your dog raw fish. Raw or undercooked fish can carry harmful bacteria such as salmonella and listeria, which are harmful to dogs and humans, especially children or people with compromised immune systems.

2. Organ Meats

Organ meats like liver, heart, and kidneys are rich in magnesium. The liver should be fed in small amounts and not every day. It contains a considerable amount of vitamin A, and consumption of large portions can lead to vitamin A toxicity.

If you serve raw organs, it is important to be aware that bacteria such as salmonella, E. coli, and listeria are commonly found in raw meat. Therefore, it’s crucial to take precautions when handling and feeding raw meat, such as washing your hands after touching it and cleaning every surface it touches. Raw food is especially hazardous to children or people with compromised immune systems.

You don’t need to feed your dog organs every day. Instead, aim for a variation in their diet. If this is the first time your dog has had raw meat, start with small amounts and gradually increase them.

3. Whole Grains

You can prepare the grains similarly to how you cook them for humans; for example, you can boil rice in water. Avoid adding other ingredients like dairy or fats. Once it’s prepared, you can add the rice to your dog’s food. You can also serve a small portion as a treat if your dog enjoys it. If feeding as part of a home-cooked diet, follow a recipe from a veterinary nutritionist to ensure your dog’s diet is balanced.

4. Beans

Beans can be prepared for dogs the same way they’re cooked for people. Dogs can have beans that have been soaked and then cooked, but they shouldn’t consume uncooked beans because they’re nearly indigestible.

Green beans are also a good option; despite their name, they aren’t in the bean family. You can serve them fresh or cooked, but avoid canned beans since they generally have added sodium and preservatives. The ideal option is to purchase fresh beans from the grocery store, but if you choose flash-frozen green beans, steam or microwave them to thaw them out until they’re ready to cook.

5. Vegetables

Cucumbers are an excellent treat for your dog because there are only 8 calories per ½ cup. Make sure you cut the cucumber into manageable sizes, especially if you have a small dog or one that likes to wolf down their meals. The best way to prepare spinach for your dog is to steam it. Boiled spinach loses most of its nutrients, and raw spinach is hard to digest.

When you steam it, keep it plain and chop it so it’s easier for your dog to digest. You should only add small amounts of spinach to your dog’s diet since too much can damage the kidneys or cause digestive problems. Green peas are a healthy snack, and you can cook frozen, fresh, or thawed peas. Avoid canned peas since they have too much sodium.

6. Fruits

You can serve several nutritious fruits to your pup. Bananas are a healthy snack you can mash up in your dog’s food, stuff into a dog toy like a Kong, or slice and freeze. However, it’s best to avoid the peel; while it’s not toxic, it can be difficult to digest and could cause a blockage.

You can also cut up a cantaloupe into half-inch pieces and feed them to your dog. Make sure you remove the rind and seeds. If your dog is a little fussy, you can mash it up and add it to their food. Cooked pumpkin ( avoiding the stem, leaves, and skin) is safe for dogs and a source of magnesium, among other nutrients. You can also serve canned pumpkin as long as it is plain. Avoid pumpkin blends and mixes, such as pumpkin pie filling, which contains other ingredients that can harm dogs.

Remember, fruits are higher in sugar, so they should only be an occasional treat.
