DMSO & MSM for Dogs and Cats - Dr. Jutta Ziegler

DMSO & MSM – Two Underestimated Sulfur Compounds in Medicine by Dr. Jutta Ziegler

DMSO (dimethyl sulfoxide) and MSM (methylsulfonylmethane) are among the most exciting yet least-used active ingredients in modern medicine—even though their effects have been researched and well documented for decades. In this volume of the “Therapeutics” series, holistic veterinarian Dr. Jutta Ziegler explains why these two sulfur compounds receive little attention in conventional medicine, what role economic interests play in this, and what potential they hold, particularly in veterinary medicine.

What are DMSO and MSM?

This booklet provides a step-by-step introduction to the basics of DMSO and MSM. DMSO is presented as an organic sulfur compound that was originally discovered as a byproduct of pulp and paper production and is now synthetically produced in high purity. It is colorless, highly soluble, penetrates biological membranes particularly well, and has anti-inflammatory, pain-relieving, and circulation-enhancing effects. MSM is described as a natural oxidation product of DMSO that occurs in the global sulfur cycle and has been used as a dietary supplement since the 1980s—primarily to support joints, connective tissue, and skin.

Sulfur in the Bodies of Dogs and Cats

A central chapter is devoted to the importance of sulfur for the bodies of dogs and cats. Dr. Ziegler explains that sulfur, as an essential macronutrient, plays a key role in structural proteins, enzymes, detoxification processes, skin, coat, claws, and the immune system. It clearly highlights why “not all sulfur is the same”: Essential sulfur requirements are met through sulfur-containing amino acids such as methionine and cystine, while MSM can act as a complementary source of functional sulfur but does not replace proteins. For dogs and cats, typical deficiency symptoms such as a dull coat, poor wound healing, and increased susceptibility to infections are described.

DMSO in Practice: Properties, History, Applications

The brochure traces the fascinating history of DMSO—from its accidental discovery in the 19th century through intensive medical research in the 1950s and 1960s to its ban by the U.S. FDA. Dr. Ziegler explains why DMSO, despite its impressive effects as a “miracle cure,” never became widely established and is used today primarily in naturopathy, equine medicine, and holistic veterinary medicine. Specific areas of application are described, such as tendon and ligament injuries, joint inflammation, swelling, and soft tissue injuries. With a practical focus, she discusses dilutions, suitable mixing liquids, topical applications, injections, and infusions, and warns against the so-called “Trojan effect”—that is, the absorption of unwanted substances through the skin.

MSM: Support for Joints, Connective Tissue, and Skin

In the section on MSM, Dr. Ziegler explains why MSM is considered a well-tolerated, organic source of sulfur and how it can be used for joint disorders, osteoarthritis, chronic inflammation, skin problems, and connective tissue in need of regeneration. The focus is on supporting joint cartilage, tendons, ligaments, and the musculoskeletal system, as well as on the role of MSM in oxidative stress and the immune system. Recommended combinations with vitamin C, glucosamine, chondroitin, hyaluronic acid, omega-3 fatty acids, curcumin, and minerals are presented. For dogs and cats, there are specific feeding recommendations in mg/kg of body weight, including guidance on gradual introduction, maximum dosage, and precautions for liver and kidney diseases.

DMSO vs. MSM—When to Use

Which Substance A separate chapter clearly compares DMSO and MSM. It explains their formation, chemical properties, oxidation states, mechanisms of action, and typical applications. DMSO is described as a more reactive, short-acting, pharmacologically active form—with strong anti-inflammatory effects, pain relief, and a transport function through the skin. MSM is the more stable, more highly oxidized form, with a focus on long-term support for connective tissue, joints, and certain detoxification processes. The brochure makes it clear that both substances complement each other and should be used differently depending on the specific goal.

Who is this booklet intended for?

“DMSO & MSM—Two Underestimated Sulfur Compounds in Medicine” is aimed at pet owners who want to learn about natural supplements to conventional medical therapies, as well as animal naturopaths, veterinarians with a naturopathic orientation, and interested therapists. In a concise format, you’ll receive a well-founded overview of the history, biochemistry, practical application, and limitations of these substances—including illustrative examples and clear warnings regarding safe use.
