DMSO for Dogs: Benefits, Risks & Responsible Use

Why DMSO is Getting Attention in Canine Care

DMSO (Dimethyl Sulfoxide) has been used in veterinary medicine for decades, particularly in horses, but in recent years it has also gained interest for certain canine health issues.

Known for its anti-inflammatory and pain-relieving properties, DMSO’s ability to penetrate skin and carry compounds into tissues makes it a unique tool in a vet’s toolkit. But with that power comes a clear need for safe, controlled use — especially for our four-legged family members.

This guide will explain how DMSO is used for dogs, the potential benefits, the risks, and why veterinary guidance is non-negotiable.

What is DMSO and How is it Used in Dogs?

DMSO is an organic solvent derived from wood pulp, with medical and veterinary applications that date back to the 1960s. In dogs, it has been explored for:

• Reducing inflammation in joints, skin, and soft tissues.
• Managing pain from arthritis or injury.
• Supporting wound healing by reducing swelling.
• As a carrier for other veterinary medications, improving absorption.

Why Vets Sometimes Recommend DMSO for Dogs

Anti-inflammatory Action

DMSO can reduce swelling by lowering the inflammatory response in tissues. This is particularly useful in joint issues like arthritis.

Pain Relief

It’s believed to block certain nerve signals involved in pain, making it helpful in chronic discomfort.

Enhanced Drug Delivery

DMSO’s unique ability to carry other compounds through the skin means it can be paired with other treatments for faster, more targeted relief.

Forms of DMSO Used in Canine Care

DMSO for dogs is usually provided by vets in:

• Liquid – for topical application to affected areas.
• Gel – easier to control and apply without dripping.
• Diluted solutions – to reduce irritation on sensitive skin.

Risks and Side Effects in Dogs

Skin Irritation

Dogs can experience redness, dryness, or discomfort at the application site.

Garlic-like Odour

Just like in humans, DMSO can cause a temporary garlic smell in the breath or skin.

Potential Toxins Absorbed

Because DMSO carries substances through the skin, contamination from grooming products, dirt, or chemicals is a serious risk.

Behavioural Changes

Some dogs may appear lethargic or unsettled after application.

Myth vs Fact – DMSO for Dogs

Myth: DMSO is safe for any dog if you buy it online.
Fact: Only pharmaceutical-grade, vet-approved DMSO should be used on animals.

Myth: You can use the same DMSO on dogs that’s sold for humans.
Fact: Veterinary-grade formulations may differ in concentration and purity.

Myth: If a little helps, more is better.
Fact: Overuse can increase irritation and risk without added benefit.

Myth: DMSO works instantly.
Fact: It can provide fast relief, but underlying conditions still require veterinary management.

Legal and Ethical Considerations

In many countries, including the UK, DMSO for animal use should be supplied and overseen by a licensed vet. Self-prescribing or using industrial-grade DMSO on pets is unsafe and may be illegal.

How to Minimise Risks When Using DMSO on Dogs

Always Consult Your Vet

Never start DMSO without veterinary guidance — dosage, concentration, and application site all matter.

Apply to Clean, Dry Skin

Ensure the area is free from shampoos, flea treatments, or dirt before application.

Use the Correct Concentration

Your vet will determine the safest formulation for your dog’s size, breed, and condition.

Monitor for Side Effects

Watch for skin reactions, behavioural changes, or digestive upset.

When DMSO Should Not Be Used in Dogs

• On open wounds without veterinary approval.
• In pregnant or lactating dogs.
• Alongside certain medications without vet clearance.
• If the dog has known liver or kidney issues.
