If your once-energetic pup has slowed down—limping, stiff joints, or just not as playful as they used to be—you’re not alone. Aging, arthritis, and injuries can put a red light on your dog’s movement. But what if there was a way to give them the green light to run, jump, and play again?

Enter laser therapy—a game-changing, non-invasive treatment that’s helping dogs heal faster, reduce pain, and get their zoomies back without pills or surgery. This high-tech wellness hack is already making waves in human medicine. Now, veterinarians are using it to help dogs recover from injuries, manage chronic conditions, and even bounce back from surgery.

Here’s what you need to know about how laser therapy works, the conditions it treats, and why more pet owners are turning to this innovative approach for their dogs’ health.

What Is Laser Therapy For Dogs?

Suppose your dog is slowing down, struggling with stiff joints, or recovering from an injury. You’re likely looking for effective ways to help them feel better without relying on endless medications or invasive treatments. Laser therapy offers a solution.

This non-invasive treatment uses specific wavelengths of light to stimulate healing, reduce inflammation, and relieve pain.

Light therapy has been used for years in anti-aging treatments, skincare, detoxification, pain management, and muscle recovery. Given its success in human health, it’s no surprise that veterinarians now use light therapy to help dogs recover from injuries, manage chronic conditions, and improve mobility.

Unlike surgical lasers that cut tissue, these lasers work at a lower intensity, penetrating deep into cells to accelerate natural healing processes. This makes it an appealing option for pet owners looking for drug-free pain relief and faster recovery times for their dogs.

How Does Light Therapy Work?

Light therapy, also known as photobiomodulation, is an umbrella term for treatments that use specific wavelengths of light to stimulate healing. This category includes laser therapy, infrared light therapy, and LED (Light Emitting Diode) therapy. While the light sources differ in intensity and penetration depth, all forms aim to reduce inflammation, improve circulation, and accelerate tissue repair.

The key to its effectiveness is how light interacts with the body’s cells. Targeted wavelengths penetrate the skin and underlying tissues, stimulating mitochondria—the powerhouse of cells—to produce more adenosine triphosphate (ATP), the energy source that fuels cellular repair and regeneration (i.e., boosting cellular energy to speed up healing). This process helps accelerate recovery and reduce discomfort.

Additionally, light therapy triggers the release of nitric oxide, which dilates blood vessels, improving circulation and oxygen delivery to damaged tissues. These biological responses contribute to reduced pain, enhanced healing, and improved mobility in dogs undergoing laser therapy.

Types of Light Therapy: What’s the Difference?

Not all light therapy is the same. Different wavelengths of light penetrate to various depths and trigger varying biological responses. Understanding these distinctions is key to choosing the most effective treatment for a condition.

Red Light Therapy & Near-Infrared Light Therapy

Both red and near-infrared (NIR) light are used in therapeutic applications, but they target different layers of tissue:

• Red Light (620-750 nm): This visible light penetrates the surface layers of the skin and is effective for treating wounds, inflammation, skin health, circulation, and superficial pain relief. Think of red light as a gentle sunbeam on your skin, providing warmth and surface-level benefits.
• Near-Infrared Light (750-1200 nm): Invisible to the human eye, NIR light reaches deeper into muscles, joints, and nerves, making it ideal for pain management, muscle recovery, joint health, inflammation reduction, and nerve regeneration. It’s like warmth soaking into your muscles after sitting in the sun for a while.

Low-Level Laser Therapy (LLLT) & Cold Laser Therapy

These two forms of laser therapy are often used interchangeably, but they share distinct characteristics:

• Low-Level Laser Therapy (LLLT): Uses red or NIR light to stimulate cellular function without generating high heat. It is used for pain relief, inflammation reduction, and tissue repair.
• Cold Laser Therapy: A subset of LLLT, cold laser therapy utilizes longer, low-energy wavelengths that do not produce heat, making it safe for chronic pain management and surface-level skin issues, like minor wounds and hot spots.

Most therapeutic lasers emit red and near-infrared wavelengths, allowing for surface-level and deep-tissue treatment.

Laser therapy devices are also classified by power output. Depending on their intensity, cold lasers and LLLT can fall under either Class 3 or Class 4. Increased power allows clinicians to treat larger areas faster, but it may also increase the risk of thermal damage, which is why Class 4 lasers are typically limited to clinical use.

How to Compare At-Home Laser Devices

When comparing at-home laser therapy devices, you’ll notice differences in terms like wavelength, power output, and number of diodes. Here’s what those mean and why they matter:

• Wavelength (measured in nanometers or nm) determines how deeply the light can penetrate. Red light (around 650nm) is best for surface-level issues, while near-infrared (around 850nm) reaches deeper tissues like muscles and joints.
• Power Output (measured in milliwatts or mW) impacts the intensity and efficiency of treatment. Higher-powered lasers can treat deeper tissues more quickly, but lower-powered lasers may be safer and sufficient for surface-level care.
• Diodes are the individual light sources built into the device. Devices with more diodes spread light over a wider area—ideal for large joints or backs. Devices with fewer, higher-powered diodes offer focused, deep-penetrating treatment for targeted relief.

More diodes doesn’t always mean better—it depends on your dog’s needs. For example, a belt-style device with many diodes may be great for hip dysplasia, while a handheld laser with fewer, stronger diodes may be more effective for pinpointing areas like the knee or shoulder.

Choosing The Right Therapy For Your Dog

The type of light therapy best suited for a dog depends on the condition being treated. Red light therapy is beneficial for superficial wounds and inflammation, whereas near-infrared and laser therapy are more effective for deep muscle and joint issues. Veterinarians tailor treatment plans based on the dog’s specific needs, ensuring optimal healing outcomes.

Is Laser Therapy Backed By Science?

Yes, a wealth of scientific research supports the effectiveness of laser therapy. Studies have demonstrated its effectiveness in reducing pain, decreasing inflammation, and accelerating tissue healing in both humans and animals.

Veterinary studies have confirmed the benefits of laser therapy for conditions like osteoarthritis, wound healing, and post-surgical recovery. While results can vary based on factors like wavelength, dosage, and treatment duration, the overall consensus is that properly applied laser therapy is a safe and effective tool in veterinary medicine.

Conditions Treated By Laser Therapy

Laser therapy treats various conditions in dogs, particularly those related to pain, inflammation, and tissue healing. Common applications include:

• Arthritis & joint pain – Helps reduce inflammation and improve mobility in dogs with osteoarthritis and degenerative joint disease.
• Ear infections – Helps with chronic ear infections by reducing inflammation and promoting circulation.
• Hip dysplasia – Provides pain relief and supports joint function for dogs with hip dysplasia.
• Intervertebral disc disease (IVDD) – Aids in reducing inflammation and promoting nerve healing in spinal injuries.
• Lick granulomas & hot spots – Aids in healing persistent skin irritations and reducing inflammation.
• Neurological conditions – Supports nerve regeneration in cases of paralysis or nerve damage.
• Post-surgical recovery – Reduces swelling and pain while promoting tissue regeneration after surgery.
• Soft tissue injuries – Speeds healing for sprains, strains, and ligament injuries.
• Wound healing – Enhances recovery from surgical incisions, cuts, and abrasions.

Laser Treatment For Arthritis In Dogs

Research has demonstrated the effectiveness of laser therapy in improving mobility and reducing discomfort in dogs with osteoarthritis.

A Veterinary Medicine and Science study observed that dogs treated with low-level laser therapy exhibited increased daily activity and step counts shortly after beginning treatment, indicating enhanced mobility.

Another randomized, double-blinded, controlled trial reported that photobiomodulation therapy significantly reduced pain levels and improved clinical outcomes in dogs with moderate to severe hip osteoarthritis.

Additionally, a preliminary clinical study noted that laser therapy improved the quality of life for dogs with osteoarthritis, as perceived by their owners, and decreased the need for systemic analgesics. Importantly, no side effects were observed during the study.

Comparison With Other Arthritis Treatments

Laser therapy presents a drug-free alternative to traditional arthritis treatments such as nonsteroidal anti-inflammatory drugs (NSAIDs). Unlike NSAIDs, which can have gastrointestinal or kidney-related side effects, laser therapy has been shown to reduce pain and inflammation without adverse effects.

Furthermore, laser therapy can complement other treatment modalities, including joint supplements and physical therapy, providing a comprehensive approach to managing canine arthritis.

How Is Laser Therapy Performed In Dogs?

Laser therapy is a low-stress, non-invasive procedure that a veterinarian or a trained professional typically performs in a veterinary clinic. The process is generally quick, comfortable, and painless for your dog. Here’s what to expect when getting laser therapy through your vet:

Initial Consultation

Before starting laser therapy, the veterinarian will perform a thorough examination to assess your dog’s condition and determine if laser therapy is the right treatment option. They will also create a customized treatment plan based on your dog’s needs.

Placement & Positioning

During the treatment, your dog will be awake and typically lie down or sit. Sedation or restraint is rarely necessary, as most dogs find the experience pleasant and may even relax or sleep during the procedure. Depending on the area being treated, your dog may wear protective goggles, or an assistant may help direct their eyes away from the laser beam to ensure safety.

Laser Application

A handheld laser wand is gently moved back and forth over the treatment area, producing a slightly warming sensation on your dog’s fur. The light from the laser penetrates the skin and stimulates cellular activity to promote healing, reduce inflammation, and alleviate pain. During the session, your dog may feel mild warmth or tingling, but no pain is involved.

Session Duration

Each laser therapy session typically lasts up to 30 minutes, depending on the size of the area being treated and the severity of your dog’s condition. Smaller treatment areas require less time, while larger or deeper areas may take longer.

Number Of Sessions

The number and frequency of treatments will vary based on the injury and laser type. Your dog may initially need 2–3 sessions a week for acute conditions or injuries, with fewer sessions as improvement is seen.

Chronic conditions, such as arthritis, may require ongoing maintenance sessions, usually once every 2–4 weeks. Some dogs show significant improvement after just one or two sessions, while others may need multiple sessions before noticeable results are observed.

Post-Treatment Care

No recovery time is needed after laser therapy, and your dog can resume normal activities immediately following the treatment. If your dog needs multiple sessions, the positive effects typically build up over time, leading to reduced pain, increased mobility, and improved quality of life.

Laser Therapy For Dogs At Home

Cold laser therapy, once primarily reserved for use in veterinary clinics, is now available for dog owners to use at home. The technology has advanced significantly, making it easier and more affordable for pet parents to administer treatments independently. However, there are important considerations when deciding whether to use an at-home device.

Do At-Home Devices Work?

At-home laser therapy devices can be effective for certain conditions, especially as part of a comprehensive treatment plan. These devices typically use low-level lasers that deliver a lower light frequency than those used in veterinary clinics. While they aren’t as powerful as the professional-grade equipment, they can still provide many of the same benefits, including:

• Improved healing: Promoting tissue repair and recovery, especially in less severe injuries or ongoing conditions.
• Pain relief: Helping alleviate discomfort from conditions like arthritis, soft tissue injuries, or muscle strains.
• Reduced inflammation: Assisting in managing inflammation, especially in cases of chronic pain.

At-home devices may be less effective for deep tissue injuries or more serious conditions requiring stronger Class 4 laser therapy. Class 4 lasers are typically only used by veterinary professionals due to safety regulations regarding the power and intensity of the laser beam.

Best Laser Therapy Device For Dogs: What To Look For

When looking for a cold laser therapy device for home use, it’s essential to choose one that’s designed specifically for pets and meets the following criteria:

• Effective wavelength: Devices that offer a wavelength range of 600-1000 nm are ideal for treating both superficial and deeper issues. However, keep in mind that these devices won’t have the same deep tissue penetration as professional-grade lasers.
• Safety features: Look for devices with built-in safety mechanisms, such as automatic shut-off or protective features, to prevent overuse or accidental harm. Some devices come with protective eyewear to safeguard your dog’s eyes from the laser light.
• Reputation & reviews: It’s always wise to check reviews and recommendations from other dog owners, veterinarians, and pet health professionals to ensure the device you’re considering is effective and safe.
• Ease of use: Choose a device that is simple to operate and comfortable to handle. Some devices come with adjustable settings so you can tailor the intensity of the light according to your dog’s condition.

When exploring pain management options for your dog, it’s helpful to compare different therapies to understand their benefits, drawbacks, and how they work together. Below is a chart comparing Laser Therapy with pain medications, acupuncture, hydrotherapy, physical therapy, and supplements to help guide your decision.

My Personal Experience With Light Therapy For Dogs

While I haven’t used laser therapy on my dog, Rio, I have had a unique experience with infrared (NIR) therapy. Once, while using my infrared sauna, Rio jumped in and refused to leave. He loved the heat, and after researching, I discovered that it is safe for dogs to use infrared saunas.

To clarify, there are two main types of saunas: regular saunas and infrared saunas. Regular saunas work by heating the air around you, which in turn heats your body. In contrast, infrared saunas use infrared light to warm your body, bypassing the air directly. This allows for deeper penetration into tissues, which is why infrared saunas are often considered more effective for pain relief and muscle recovery.

The benefits of infrared sauna therapy for dogs can be similar to those of humans, including improving circulation, promoting relaxation, and potentially aiding muscle recovery and joint pain relief. However, I made sure to limit Rio’s time in the sauna to avoid overheating, ensuring a safe and controlled experience for him.

Since Rio is working on losing weight, I plan to increase our physical activity together. As part of his recovery plan, I’m considering incorporating the infrared sauna into our routine. The heat and improved circulation may help his muscles recover after long walks and runs, making it easier for him to stay active and healthy throughout the weight loss journey.
