Red Light Therapy for Pets: A Vet’s Perspective

Red Light Therapy (RLT), also known as photobiomodulation, is a therapeutic technique that uses low-level red or near-infrared light to stimulate cellular function. This non-invasive treatment has been used in human medicine for a variety of conditions, including skin issues, muscle recovery, and mental health disorders. Recently, it has also gained attention in the field of veterinary medicine.

From a veterinary perspective, Red Light Therapy offers a non-invasive, drug-free, and painless treatment option for pets. The therapy works by delivering wavelengths of red and near-infrared light to the pet’s body. These wavelengths penetrate the skin and are absorbed by the mitochondria in the cells. This absorption stimulates energy production, promotes healing, reduces inflammation and pain, and enhances overall cellular function.

Red Light Therapy Uses in Veterinary Medicine

  • Wound Healing

RLT can accelerate the healing process of wounds, burns, and ulcers in pets. The therapy stimulates cell regeneration and increases blood flow to the affected area, promoting faster healing.

  • Pain Relief

RLT has been shown to reduce pain and inflammation in pets suffering from conditions like arthritis and hip dysplasia. By increasing blood circulation and reducing inflammation, RLT can help alleviate pain and improve mobility in pets.

  • Skin Issues

RLT can also be beneficial for pets suffering from skin issues like dermatitis and allergies. The therapy can help reduce inflammation and promote healthier skin.

  • Post-Surgery Recovery

RLT can aid in faster recovery post-surgery by reducing inflammation and promoting tissue repair.

Preliminary studies suggest that RLT may also have potential benefits in alleviating symptoms of anxiety and depression in pets, although more research is needed in this area.

It’s important to note that while RLT can be beneficial, it should not replace regular veterinary care. Each pet is unique, and what works for one might not work for another. Therefore, it’s crucial to consult with a vet before starting any new treatment for your pet. The vet can provide guidance on whether RLT is a suitable treatment option for your pet’s specific condition and needs.

Advantages and  Disadvantages of Red Light Therapy to Veterinary Perspective

From a veterinary perspective, Red Light Therapy (RLT) offers several advantages and a few potential disadvantages.


  • Non-Invasive and Pain-Free: RLT is a non-invasive procedure that doesn’t cause any discomfort to the pet. This makes it an excellent option for pets that are sensitive to touch or have anxiety about veterinary procedures.
  • Versatile: RLT can be used to treat a wide range of conditions, from skin issues to joint pain, making it a versatile tool in a vet’s arsenal.
  • Promotes Natural Healing: RLT works by stimulating the body’s own healing processes, promoting faster recovery without the need for additional medications.
  • Few Side Effects: Unlike some treatments, RLT has very few side effects. The most common is a temporary increase in discomfort or inflammation as the body’s healing processes are stimulated.


  • Requires Multiple Sessions: RLT typically requires multiple treatment sessions to be effective, which can be time-consuming.
  • Cost: While the cost of individual sessions may not be high, the cumulative cost of multiple treatments can add up, making it a more expensive option for some pet owners.
  • Limited Research: While there is a growing body of research supporting the use of RLT in veterinary medicine, more studies are needed to fully understand its potential benefits and limitations.
  • Not a Cure-All: RLT can be a beneficial part of a comprehensive treatment plan, but it’s not a cure-all. It’s most effective when used in conjunction with other treatments as recommended by a vet.

As with any treatment, it’s important for pet owners to discuss the potential advantages and disadvantages with their vet to determine if RLT is the best option for their pet’s specific needs.
