If you thought being a dog owner was all about long walks, playtimes and snuggles, you’re not wrong. But it’s also important to familiarize yourself with your canine’s nutritional needs to ensure they stay fit, healthy and happy for as long as possible. 

Learn all about manganese for dogs in this helpful guide, including why this mineral is particularly important for puppies and young dogs whose bodies are still developing. 

You might have read about the importance of potassium or clued up on the health benefits of vitamin K, but how much do you really know about manganese for dogs? 

This essential trace mineral is vital to your pet’s diet, playing an important role in a dog’s neurological functioning, metabolism and the development of bones and connective tissue like cartilage. 

Your dog needs a steady level of manganese from birth to support their wellbeing and to prevent a manganese imbalance. But they can’t produce it themselves, so it must be obtained through their diet or a manganese supplement.

You’ve probably seen manganese listed on the back of dog food packets with The Association of American Feed Control Officials (AAFCO) recommendations. But did you know that manganese can do many wonderful things? 

Here are the manganese benefits for dogs:

Takeaway: Manganese for dogs is vital in small doses because it contributes to essential biological and metabolic processes. 

The daily recommended intake of manganese for dogs recommended by (AAFCO) for most adult dogs is 1.25 mg per every 1000 kcal ME, or 1,000 calories from food. How much manganese per day for dogs depends on factors such as age and activity levels.

Puppies require a bit more because of the mineral’s role in development: 1.8 mg. In addition, dogs with higher energy needs such as herding dogs (Welsh Sheepdog) or mushers may need an increase as well. It’s always best to get help from your vet in determining ideal manganese levels.

Foods high in manganese for dogs are easy to find on the shelves, especially if they follow AAFCO’s nutrient profiles. These ensure dogs get the right diet for their age, breed and health.

Sadly, when there’s manganese there’s sometimes glyphosate too. This creeps in because of its use in farming grains and is a contributor to pesticide poisoning in dogs. Glyphosate reduces the body’s ability to absorb and use manganese. And in some cases the chemical actually removes it.

To ensure your dog gets enough of this mineral daily, avoid kibble containing glyphosate and add foods that are high in manganese to maintain healthy levels. The following foods are just a few that are rich in manganese, with the amounts that are necessary to provide 1 mg of manganese:

Other sources, such as ground beef and beef heart, would require feeding several (or many) pounds to reach 1 mg of manganese. It's always a good idea to discuss your dog’s diet with your veterinarian before adding something new.

Foods high in manganese for dogs are beneficial in so many ways. Canines lacking in this mineral, especially puppies, might experience problems with bone and cartilage development. 

Manganese deficiency can also cause problems with the dog’s reproductive system, metabolism and bone injuries. Too little manganese in a dog’s blood can often be seen when using supplements because the manganese in them is harder to absorb.

Symptoms of a manganese deficiency might include:

Manganese deficiency can be treated with a diet change, prescribed or over-the-counter manganese supplements and the addition of manganese-rich foods to the dog’s diet. Manganese ascorbate for dogs, for example, is a powder that can help boost manganese levels.

Dietary correction is preferred because supplements can be difficult to regulate safely, sometimes causing an overdose. Nursing puppies get adequate manganese from their mother’s milk.

Manganese deficiency that may result from feeding a raw or homemade diet involves adding cereal grains, chia seeds which are notoriously high in manganese, or seafood such as green-lipped mussels to the finished product.

While a manganese overdose in dogs is rare, anemic dogs are at a greater risk. Symptoms of a manganese overdose can include:

Since signs of an overdose can take a long time to appear due to the mineral’s slow absorption rate, it’s important to monitor your dog’s behavior, gait, appearance, and growth on a regular basis and note any abnormal changes or irregularities to your veterinarian.

Foods high in manganese for dogs prevent the need for supplements in many cases, especially as the daily amount needed for a canine’s well-being is low. That said, when sufficient amounts of manganese aren’t available in a dog’s diet, veterinarians and dog parents may turn to supplementation to prevent the long-term health effects of a manganese deficiency. 

There are many supplements on the market, including tablets, capsules, and liquids. Your vet is a valuable resource when choosing a supplement for your dog. So don’t hesitate to seek out advice and support regarding manganese for dogs.

Restoring healthy manganese levels can sometimes be difficult. Manganese from any source is absorbed slowly and any positive or negative effects of the chemical may take up to two weeks to appear. 

It’s important during this time to be patient, and if necessary, increase the amount of supplement in very small increments, then have the pup’s blood level tested. As discussed previously, too much manganese can be dangerous, too.

Manganese is a critical mineral nutrient in a dog’s diet and feeding your puppy the right food is essential to facilitate growth. A good first step is to check the amount of manganese in a bag of your dog's regular food.

Observation of the aforementioned signs of a deficiency or overdose may alert you to a manganese imbalance and injuries or conditions such as cruciate ligament failure or bowed front legs may be your first clue. 

Many foods high in manganese for dogs  can be used to supplement a canine’s usual diet to help keep manganese levels in a healthy range. Puppies and still-growing young dogs require more manganese than adult dogs, and the breed and size may also impact the ideal level, so always chat with your veterinarian to find out what your canine needs.
