Red light therapy is not just for humans. Veterinary photobiomodulation has a robust and growing evidence base, particularly for canine patients. Dogs suffer from many of the same conditions that respond to PBM in humans β arthritis, soft tissue injuries, post-surgical wounds, and chronic pain. And unlike humans, dogs do not experience a placebo effect, which makes the positive outcomes in veterinary studies especially compelling.
This guide covers the evidence for red light therapy in dogs, the best devices designed for canine use, safety considerations, treatment protocols, and practical advice for dog owners considering PBM for their pets.
The Evidence for Red Light Therapy in Dogs
Canine Arthritis
Osteoarthritis affects approximately 20% of dogs over the age of one and up to 80% of dogs over eight years old (Anderson et al., Veterinary Surgery, 2020). It is the most common reason dog owners seek PBM treatment.
A 2017 randomised, double-blind, placebo-controlled trial by Looney et al. published in Veterinary Surgery (DOI: 10.1111/vsu.12680) found that PBM at 810 nm significantly reduced pain and improved mobility in dogs with elbow osteoarthritis. Dogs receiving active treatment showed measurable improvements in gait analysis and owner-assessed pain scores compared to the sham group.
Draper et al. (2012) demonstrated that PBM at 810 nm produced significant pain relief in dogs with stifle (knee) osteoarthritis, with effects lasting up to 3 weeks after a treatment course (Veterinary Record, DOI: 10.1136/vr.100275).
Wound Healing
PBM accelerates wound healing in dogs through the same mechanisms as in humans β increased ATP production, enhanced fibroblast activity, and collagen synthesis stimulation.
Oliveira Sampaio et al. (2017) published a controlled study in Photomedicine and Laser Surgery showing that 660 nm and 808 nm PBM significantly accelerated surgical wound closure in dogs, with treated wounds showing 40% more rapid healing compared to controls (DOI: 10.1089/pho.2016.4149).
Post-Surgical Recovery
Veterinary surgeons increasingly use PBM post-operatively, particularly after orthopaedic procedures (cruciate ligament repair, fracture fixation, spinal surgery). The evidence suggests PBM reduces post-operative inflammation, accelerates tissue repair, and may reduce pain medication requirements.
Rogatko et al. (2017) found that dogs receiving PBM after tibial plateau levelling osteotomy (TPLO) β the most common cruciate ligament surgery in dogs β showed significantly better limb function at 8 weeks compared to controls.
Intervertebral Disc Disease (IVDD)
IVDD is particularly common in breeds like Dachshunds, French Bulldogs, and Beagles. PBM has shown promise as an adjunct to conservative management of IVDD.
Draper et al. (2012) reported that class IV laser therapy (a form of PBM) improved neurological function in dogs with thoracolumbar IVDD, though the study was small and uncontrolled.
Other Applications
Emerging evidence and clinical experience support PBM use in dogs for:
- Ear infections (otitis) β reducing inflammation in the ear canal
- Hot spots and dermatitis β accelerating skin healing
- Lick granulomas β breaking the itch-lick cycle through anti-inflammatory effects
- Gum disease and dental pain β oral PBM is used in some veterinary dental practices
- Tendon and ligament injuries β particularly in sporting and working dogs
- Age-related cognitive decline β transcranial PBM is an active research area in veterinary neurology
Choosing a Device: Veterinary vs Consumer
There are two categories of red light therapy devices used on dogs:
Veterinary-Grade Devices
Designed specifically for animal use, sold primarily through veterinary equipment suppliers, and often requiring professional training.
- Higher power output (Class IIIb or Class IV lasers, or high-irradiance LED arrays)
- Veterinary-specific treatment protocols programmed in
- Durable construction for clinical environments
- Significantly more expensive (Β£1,000βΒ£20,000+)
- Often require veterinary supervision
Consumer-Grade Devices
LED panels and wearable devices marketed to pet owners for home use.
- Lower power output (Class I or II)
- General-purpose protocols
- More affordable (Β£50βΒ£500)
- Safe for unsupervised home use
- Variable quality β the market includes excellent products and ineffective ones
Both categories can be effective if they deliver the correct wavelengths at sufficient irradiance. The key difference is power output, which determines treatment time and depth of penetration.

Treatment Protocols for Dogs
General Guidelines
Veterinary PBM dosing follows similar principles to human PBM but adjusted for coat thickness, skin pigmentation, and body size:
- Wavelength: 660 nm for superficial conditions (wounds, skin issues), 850 nm for deep tissue (joints, muscle, bone)
- Dose: 1β8 J/cmΒ² per treatment point for superficial conditions, 4β12 J/cmΒ² for deep tissue
- Frequency: Daily for acute conditions (first 1β2 weeks), then 2β3 times weekly for chronic conditions
- Coat considerations: Dark, thick coats absorb and scatter more light. Increase dose by 20β30% for heavily coated breeds. Clipping is not necessary but does improve light transmission.
Arthritis Protocol
- Identify affected joints β your vet can confirm which joints show arthritic changes on radiographs
- Treat each joint for 1β3 minutes per point (depending on device irradiance)
- Cover multiple angles β treat from the lateral (side), medial (inner), and anterior (front) aspects of each joint
- Frequency: Daily for the first 2 weeks, then 3β4 times weekly
- Duration: Ongoing β arthritis is chronic, and PBM management is long-term
- Monitor: Track your dogβs mobility, willingness to exercise, and pain indicators (reluctance to jump, stiffness on rising, altered gait)
Post-Surgical Protocol
- Wait until incision is closed β do not treat open wounds with consumer devices without veterinary guidance
- Treat around (not directly on) the surgical site for the first 3β5 days
- Treat directly over the incision from day 5β7 onwards
- Frequency: Daily for 2 weeks, then every other day for 2 weeks, then 2β3 times weekly until recovered
- Coordinate with your vet β PBM should complement, not replace, post-surgical care protocols
Wound Healing Protocol
- Clean the wound according to veterinary instructions before each treatment
- Treat the wound margins (edges) and the wound bed
- Use 660 nm primarily β superficial tissue response
- Frequency: Daily until closure, then every other day until fully healed
- Watch for signs of infection β PBM supports healing but does not replace antibiotics if infection is present
Safety Considerations
Eye Protection
Dogsβ eyes are sensitive to bright red and near-infrared light. Protect your dogβs eyes during treatment:
- Do not direct the light beam at your dogβs eyes
- If treating the face or head, cover the eyes with a soft cloth or use pet-safe goggles (available from veterinary suppliers β Rex Specs is a popular brand)
- Most dogs will naturally close their eyes or look away from bright light
Contraindications
Do not use PBM on your dog without veterinary consultation if:
- Active cancer or tumours β PBM increases cellular metabolic activity, which could theoretically stimulate tumour growth. The evidence is mixed, but the precautionary principle applies.
- Pregnancy β avoid treating over the abdomen of pregnant dogs
- Active haemorrhage β PBM increases blood flow, which could worsen active bleeding
- Over the thyroid β the canine thyroid sits in the neck; prolonged PBM over this area may affect thyroid function
Coat and Skin Considerations
- Dark-coated dogs absorb more light at the surface. This is not dangerous but means less light reaches deeper tissues. Increase treatment time by 20β30% for very dark coats.
- Shaved or clipped areas receive more light β reduce treatment time accordingly to avoid exceeding optimal dose.
- Irritated or infected skin β PBM can be used on inflamed skin but should not be used on actively infected wounds without veterinary oversight.
Temperature
Ensure the device does not overheat against your dogβs skin. Most LED devices generate minimal heat, but laser devices and panels pressed directly against fur can warm up. Check the device surface temperature periodically during treatment.
Working With Your Vet
The best outcomes come from integrating PBM with conventional veterinary care:
- Get a diagnosis first. PBM is a treatment tool, not a diagnostic one. Before starting therapy, have your vet confirm the condition you are treating.
- Share your plan. Inform your vet that you are using PBM at home. Most vets are increasingly aware of the evidence and will be supportive.
- Track outcomes. Keep a simple log of treatment dates and your dogβs condition (mobility score, pain indicators, activity level). Share this with your vet at check-ups.
- Do not replace medication without veterinary advice. If your dog is on NSAIDs or other pain medication, do not reduce or stop these without consulting your vet, even if PBM seems to be helping.
The Bottom Line
Red light therapy for dogs is not a trend β it is an evidence-based treatment modality with genuine clinical support. The veterinary literature consistently shows benefits for canine arthritis, wound healing, and post-surgical recovery.
For most dog owners, the Photizo Vetcare (Β£350βΒ£450) is the best investment β it delivers clinically relevant doses with pre-programmed protocols that remove the guesswork. If budget is a concern, the LumaSoothe 2 (Β£120βΒ£170) offers a solid entry point. For dogs with chronic joint issues who need daily hands-free treatment, the PetThera Pad is worth considering.
Whatever device you choose, remember that PBM works through cumulative biological effects. Consistency matters more than any single session. Treat daily, track outcomes, and work with your vet. Your dog cannot tell you it is working, but improved mobility, willingness to exercise, and reduced stiffness on rising will show you.
