MSM For Dogs – What Is MSM For Dogs And Which Is The Best?

MSM, scientifically known as methylsulfonylmethane, is a naturally occurring sulfur compound that is produced by sea plankton and is found in foods like meat, vegetables, fruits, nuts, cow milk, and other types of seafood (e.g. kelp). However, in production for dog supplements, it is done chemically in a manufacturing lab.​

MSM for dogs is well known for its joint health benefits. Its value as a dietary supplement was discovered by Stanley W Jacob MD, a Professor of Surgery in Portland. He found that MSM was effective in a large study of 15,000 patients.  He has also written several books about MSM.

MSM aids in fighting inflammation in the body. It is also found in many joint supplements for human beings. Because it is extremely water soluble, MSM evaporates quickly.

MSM for dogs can significantly decrease the pain and discomfort associated with arthritis, common in older dogs. MSM is a natural source of sulfur. MSM supplements usually come in combination with other nutrients such as glucosamine and chondroitin, and sometimes with Omega 3 fatty acids. These supplements are highly beneficial for the joint health of your dog.

So amidst all the available MSM supplements for dogs, which ones are the best for your pet? Following are some of the best MSM supplements available in the market.

What Makes MSM Supplements Important for Your Dog?

Often, this potentially crippling condition shows its ugly head if your dog has ever suffered some form of joint injury or has had hip dysplasia. Whenever you notice some change in the walking style of your dog, it is important that he or she is taken to a veterinarian.

Besides other forms of treatment, your veterinarian may recommend that you add a good pet joint supplement to the diet being consumed by your dog. This may also be suggested in case your dog is at risk of developing joint complications.

Different from the majority of products and compounds available for treating and managing dog’s arthritis-related conditions, MSM does not bring along too many side effects. This is a very important factor because you certainly want your pet comfortable and not subjected to lots of side effects.

If given to dogs with joint pain problem, MSM supplements can greatly reduce the damage that is being done by arthritis. While it’s true that nearly every type of MSM supplement will assist in relieving stiffness and pain that are generally associated with arthritis in dogs, there are several specific options that have been proven to be more effective than others.

Excellent Antioxidant

MSM (methylsulfonylmethane) is also an excellent antioxidant for your dog. It is useful in cleaning out the dog’s blood stream and in flushing toxins from the body cells. This is very important in terms of eradicating free radicals from the dog’s body, keeping it clean and at its healthiest state. Working as an antioxidant, MSM even helps reduce allergy symptoms.

MSM works as an antioxidant helping to clean the pet’s blood stream through flushing toxins from the body cells. It effectively plays the role of “scavenger” for free radicals and foreign proteins, assisting in eliminating toxins through the animal’s skin. This reduces the burden that would have been placed on the kidneys and the liver. Allergens get eliminated more quickly, in turn helping in reducing allergy symptoms.

MSM Dosage for Dogs

As I have pointed out earlier, MSM is safe and suitable for all mammals. However, an important factor to take into consideration is your smaller size pets. It is vital you get the right dosage when giving your furry friends MSM.

The right MSM dosages will depend on the weight of your dog. MSM supplements dosages for dogs are approximately between 50 and 100 grams for every 10 pounds. Ideally, for every 25 pounds mass, cats and dogs should be given approximately one-eighth of a teaspoon of MSM once daily.

If your dog that weighs 20 pounds, for example, he or she should get about100 grams of MSM. MSM supplements for dogs is available in both capsule and powder form. Neither of these is known to have any side effects. It all comes down to your personal preference and the ease with which your dog consumes the supplement. And the cleaning afterwards!

Relieves Joint Pain and inflammation

The result of inflammation is swelling of cells, producing joint/muscle pressure and pain. MSM is a joint healer, reducing inflammation and relieving pain, especially for an aging dog. Whether the pain is a result of arthritis or any other medical condition, MSM allows easier passage of fluids through the body tissues, thus equalizing the pressure and reducing pain levels.

Sulfur is an essential element in the formation of connective tissues, blood proteins, amino acids, and a healthy skin. MSM, the sulfur compound is stored in nearly every cell of the body, with the highest concentrations located in bones, skin, joints, muscles, nails, and hair.​

As the body ages, the concentration of MSM reduces, making its deficiency to be part of the normal aging process. Low MSM concentrations can lead to:​

  • Organ failure
  • Body tissue malfunctions
  • General fatigue
  • Physical and psychological stress

Deficiency of sulfur in dogs can lead to a poor digestion system, arthritis, joint pain, skin problems, dull coat, and poor immune system.

The MSM effects are quite amazing, truly helping your dog get the bounce back into their life. This makes it easier to move their body more freely, without feeling too much discomfort or pain or even altogether eliminating the root of the pain.

Supports Healthy Cells and Skin

MSM (methylsulfonylmethane) is an essential compound in supporting and maintaining healthy cells. It decreases the cell inner pressure, making the cell walls more permeable. As a result, water and nutrients flow more easily into the cells of your dog while at the same time it facilitates the out flow of toxins. Working together with Vitamin C, MSM allows the rejuvenation of body cells, thereby upholding a healthy balance of cells in the body.

As it is also responsible for the flexible bonds that exist between different cells, MSM maintains healthy skin through by enhancing the flexibility of skin tissue and helping in the repair of any skin cells that may have been damaged.


The ingredients contained in MSM are excellent anti-parasitic against parasites such as giardia, roundworms, and other forms of intestinal worms. They act by robbing the parasites of possible sites where they can attach themselves through competing for the available receptor sites on the intestines mucous membranes. The digestive system of the dog then naturally flushes them out.

Other additional MSM supplements benefits include:

  • Healthy skin and coat
  • Reduction/relief from several allergy symptoms
  • Connective tissues and joint support
  • Relief from arthritis pain and hip dysplasia.

Any dog owner cannot afford to overlook the numerous MSM benefits for dogs. As soon as you start administering MSM, improvement in the personality and behavior of your dog become clear almost immediately. Your furry friend will start to act happier and more lively, and you will also notice that overall, their mood has improved.

Is MSM Safe for Dogs? - Are There Any Contraindications?

MSM supplements are in general contraindicated in nursing or pregnant dogs. Also, according to Petinfo , because some types of medications may interact with dimethyl sulfoxide, the main compound in most MSM supplements, they shouldn't be administered together with other medicines, other supplements or herbal remedies unless advised by your pet .

MSM supplements for dogs are also contraindicated if your pet has bladder or urinary tract cancer. Let me also point out that dogs that experience allergic reactions to some specific foods, medicines, or other substances should only be given MSM supplementation under the guidance of a vet.


Today, there are many different MSM products for dogs that you can buy. You can, for example, buy the pre-made MSM products as they are, or choose to the pure MSM powder form. The powder can be sprinkled on your pet’s food. When shopping for your MSM dog supplements, ensure that it comes from licensed manufacturer, is safe for your pet.

Naturally occurring sulfur is great for the health of your dog’s joints. MSM for dogs is a nutrient that provides the needed support to your pet’s aging bones and joints. Ensure that they are natural and pure, AND whenever in doubt do not hesitate to consult your veterinarian.

Yes, just like you and me, our little furry pet companions too can benefit from getting additional MSM supplementation, but they need careful monitoring as they cannot speak for themselves and tell what the right dosage is for their small bodies.

All the above-mentioned products are very good sources of MSM and contain the right MSM dosage for dogs. You can choose any one according to your preference.
