Why introduce photobiomodulation into veterinary care?
Dogs and cats are living longer than ever, so they're more likely to suffer from osteoarthritis, chronic wounds or dermatological disorders. Veterinary clinics are looking for gentle, pain-free solutions with no side effects to improve comfort between check-ups or after surgical emergencies.
Photobiomodulation (PBM) diffuses low-intensity red or near-infrared light that penetrates tissues without heating them. It stimulates cellular energy production (ATP), modulates the inflammatory response and supports micro-circulation and wound healing.
Major indications in dogs and cats
These light protocols complement conventional veterinary treatments (anti-inflammatories, antibiotics and dressings) without interfering with them. In a veterinary clinic, photobiomodulation or PBM is easily integrated into the standard protocol. The vet prepares the area, adjusts the wavelength (red for skin, infrared for joints) and lets the device do its work.
Indication
Joint pain (osteoarthritis), wounds and healing, dermatology, senior well-being.
Signs observed
Lameness, difficulty getting up, morning stiffness, incessant licking, crusts that are slow to close, hot spots, atopic dermatitis, itching, reduced activity, restless sleep, general discomfort.
Light contribution
Reduces inflammation, supports mobility without prolonged NSAIDs, accelerates skin regeneration, improves comfort during the animal's healing phase, calms redness, helps restore the skin barrier, overall relaxing effect, optimizes circulation in aged tissue.
How does veterinary photobiomodulation work on animals?
A therapeutic LED or laser is placed just a few centimetres from the targeted area, and the session lasts 3 to 15 minutes, depending on the surface. There's no need to shave the animal, just remove any heavy dirt to allow the photons to pass through. Light activates the mitochondria of muscle, skin and nerve cells, encourages collagen production, releases nitric oxide (micro-circulation) and limits the inflammatory cascade that sustains your pet's pain. The veterinary examination room remains clean, the equipment disinfects in thirty seconds and the consultation maintains its normal rhythm.
Painless
Most of the animals remain motionless, and some even fall asleep under the gentle heat.
Safe
No ultraviolet rays, no thermal effects, the veterinarian wears filtering goggles if a laser is used.
Short protocols
2 to 3 sessions a week for 3 weeks are often enough to see an improvement in your pet's general condition or wound.
Photobiomodulation at home
Pet owners can rent or buy small, secure LED panels, which are plugged into the mains, placed 5 cm from the fur and switch off automatically. At home, the animal remains in its familiar environment, reducing stress and travel, while prolonging the effect of veterinary clinic sessions.
Easy to position
An articulated arm or luminous cushion adapts to the dog's basket or the cat's favorite chair.
Simple programming
Pre-set times(5, 10 or 15 minutes) prevent errors.
Follow-up
A logbook or digital cards can be used to record your pet's mobility, appetite and pain on a visual scale.
Tips for pet owners
Here are a few tips to help you get the most out of home photobiomodulation sessions:
Key gesture
Set up a quiet area, start after the walk, observe progress, respect emergencies, remain regular.
The benefits
Reduces anxiety, facilitates immobility, the dog is more relaxed, less excited, adjust the frequency with the vet, deep wounds, fever, acute lameness: consult a vet as a matter of priority, the benefits set in session after session.
Practical tips
Place the lamp near the usual basket, offer a treat to chew on during the session, keep a mini-diary with observations, have the veterinary emergency number available, plan reminders so you don't forget anything.
Practical advice for vets
Photobiomodulation in veterinary practice requires special training to ensure the best possible treatment for animals.
1.
Establishing a protocol
Define the number of sessions, wavelength and energy density according to your pet's pathology.
2.
Photograph the area
Photo at D0 then at D14 to objectivize the evolution and reassure the owner.
3.
Adapt distance
1 cm for a laser, 2-5 cm for high-power LEDs, to obtain the ideal irradiance.
4.
Create follow-up sheets
Note pain, local heat, visual progress of skin or mobility.
5.
Team building
Show veterinary assistants how to position the lamp to save time during consultations.
