Red Light Therapy for Dogs at Home: A Vet-First Guide

Red light therapy for dogs at home can be a gentle add-on to your vet's plan, provided the vet agrees first, the light never reaches the dog's eyes and you stay with the dog for the whole session. Below: what vet studies used, who should not have light at home, eye protection, set-up, first settings, fur, stop signs and tracking.

Key takeaways

• A 2023 systematic review found 45 studies of light therapy in animals, 24 of them in dogs, and the clearest dog result came from a sham-controlled elbow arthritis trial. Millis and Bergh, 2023
• The Merck Veterinary Manual names damage to the retina and heat burns from improper use as the main risks of light therapy in animals. Merck Veterinary Manual, 2025
• In a 2022 trial of 20 police dogs with hip arthritis, no side effects were recorded in either the light group or the medicine group. Alves, 2022
• In a study of 47 healthy dogs, darker coats let less light through the skin and shaving let more through, while coat length made no significant difference. Hochman-Elam, 2020

Can you do red light therapy for dogs at home?

Yes, with your vet's agreement, using an LED panel at a distance on intact skin with the dog's head turned away. The closest evidence comes from vet-clinic laser trials in arthritic dogs, which is why the vet should set the plan.

In the clinic, staff use clinic laser therapy, sometimes called cold laser, with a handpiece on or just off the skin. The Merck Veterinary Manual uses the term photobiomodulation for the effects of both lasers and LEDs. Merck Veterinary Manual, 2025

The 2022 pain guidelines for dogs and cats list laser therapy among physical treatments that "may be useful adjuncts" for long-term pain. AAHA, 2022 Light sits alongside weight control, exercise and any medicine the vet prescribes.

Study or guide	Dogs	Light	Sessions	Course	How applied
Looney 2018, elbow arthritis, sham-controlled	20	980 nm laser	2 a week	6 weeks	On the skin over both elbows
Alves 2022, hip arthritis, compared with meloxicam	20 (40 hips)	980 nm, or 980 plus 808 nm by coat colour	3, then 2, then 1 a week; about 5 minutes each	3 weeks	Moving grid in contact with the skin over the hip
Barale 2020, several joints, no control group	17	808 nm laser	1 a week	6 weeks	Joints and the muscles around them
Huntingford 2019, vet guidance	n/a	800 to 1000 nm for joints	Daily in a flare, then 2 a week; upkeep every 3 to 6 weeks	2 to 3 weeks in the twice-weekly phase	The joint plus the muscles around it

These are clinic lasers worked over small areas by trained staff, so their numbers are not settings to copy onto a panel. Sources: Millis and Bergh, 2023, Alves, 2022, Barale, 2020, Huntingford, 2019.

Is red light therapy safe for dogs?

Generally yes, when the light stays out of the eyes and a few conditions are avoided. The risks vets name most are damage to the retina and heat burns, and both depend on how the light is used.

Merck lists retinal damage and thermal burns from improper application as the main risks. Merck Veterinary Manual, 2025 At home, both are avoided by position and by checking warmth with your hand.

In the 2022 hip trial, no side effects were recorded in either group. Alves, 2022 In a series of 17 arthritic dogs, "Laser-related side effects were not observed." Barale, 2020

A dog cannot tell you a session feels too warm. A sports medicine vet advises: "Use your hand to monitor skin temperature", because darker skin absorbs more light. Huntingford, 2019 The Kivorla panel's surface stays at or below 40°C, and the rule from is red light therapy hot applies to dogs too: warm is fine, hot means stop.

Which dogs should not have red light therapy at home?

Dogs with lumps, pregnant dogs, puppies with growing bones and any dog with an open wound, bleeding or sudden weakness need the vet rather than a panel. For a dog with a thyroid condition, keep the light off the throat and ask the vet.

A university vet hospital says a "full medical work-up" by your vet should come first. CSU Veterinary Health, 2024 The list below follows the vet references. Merck Veterinary Manual, 2025

• Lumps or cancer: never shine light over a lump, and take any new lump to the vet. Merck also lists lymphoma and immunosuppressant medicines.
• Pregnant dogs: a pregnant uterus is on every vet list, so do not use the panel on a pregnant dog. Goldberg, 2019
• Puppies: under a year, higher-powered devices may affect growth plates, so keep light off a puppy's growing bones unless the vet says otherwise.
• Wounds, hot spots and stitches: never over open wounds, broken skin, stitches or bleeding. Home sessions are for intact skin only.
• Thyroid: Merck lists an overactive thyroid, so keep the light off the throat and ask the vet.
• Tattoos: tattoo pigment absorbs a lot of light and can cause intense pain, so keep an identification tattoo out of the beam.
• Medicines and herbs: Merck advises lower intensity with light-sensitising drugs or herbs such as St John's wort. Tell the vet about every medicine your dog takes.

Sudden wobbling, dragging the back legs, crying in pain or loss of bladder control can be a disc problem, "generally thought to be a true surgical emergency". ACVS Call the vet the same day, before anything else.

How do you protect a dog's eyes from a red light panel?

By position: aim the panel at the body from the side or from behind, with the head at the far end or turned away, because dogs rarely keep goggles on. Near-infrared light is invisible, so a dog gets no glare that would make it look away.

A veterinary rehabilitation technician writes: "The only absolute contraindication for laser therapy is direct or reflected exposure" of the retina. Goldberg, 2019 Dogs resist dog goggles, so clinics turn the face away, and a towel can help keep the head settled.

Light above 760 nm cannot be seen, according to Merck, and the panel's 810, 830, 850 and 1060 nm channels fall in that range.

• Head away: the head at the far end of the panel, or the panel behind the dog.
• Front legs: lay a light towel over the face, since elbows are hard to reach without the head nearby.
• Reflections: take off a collar with metal tags and cover shiny surfaces nearby.
• Looking round: if the dog turns to look at the panel, switch it off with the controller and reposition.

The goggles in the box are for you; our goggles guide explains why they matter with near-infrared.

Can I use my own red light panel on my dog?

Yes, the Kivorla panel may be used on pets, but the distances and minutes in its manual are written for people. Your vet sets the dog's plan: the area, the distance, the minutes and how often.

The manual's figures are 6 inches for a joint, 12 inches for a broad area and 10 to 15 minutes per area. Those suit an adult who can say when skin feels too warm. A dog is smaller, has fur over the skin and cannot tell you.

How do you set up a red light panel for a dog lying on its bed?

Lower the panel on a door or stand it upright on the floor so the light falls side-on across a dog lying on its bed, with the head at the far end. Pick a quiet room and leave the dog a clear way out.

Our panel set-up guide covers the hardware in detail.

• Height: hang the panel on a door with the included door hook and pulley and lower it to the dog's body. Check the pulley is locked before you let go.
• On the floor: the panel can stand upright on the floor. A floor stand is not included; it is a separate accessory from the maker.
• Cord: route it where the dog will not walk through it or chew it.
• Nothing on top: do not drape a towel or blanket over the panel while it runs.
• Hips: the dog lies on its side with its hindquarters towards the panel.
• Lower back: the dog lies on its chest and the panel aims along the back from behind, below head height.
• Knees: the dog lies on its side; treat the other knee another day.

How far away and how many minutes for a dog's first sessions?

Agree it with your vet first; the gentle starting point in our dog articles is about 12 inches, 2 to 3 minutes at lower brightness, building to about 5 minutes on one area, 2 or 3 times a week. Use continuous mode with the pulse off.

This is a Kivorla suggestion to discuss with the vet, not a dose from a dog trial. To stay gentle, use the panel's own controls:

• Distance: about 12 inches; further away means less light per minute.
• Brightness: each wavelength dims from 1 to 100%. Turning the visible channels down also makes the panel less bright for the dog.
• Timer: it starts at 1 minute. If you set no time, the panel stops after 5 minutes.
• Mode: continuous, pulse off; see pulsed vs continuous.
• Area: one area per session.

Does red light get through a dog's fur or a black coat?

Some does, but darker coats let less light through to the skin, and parting the fur helps. In a study of 47 dogs, coat colour mattered and coat length did not.

Researchers measured light passing through the skin of 17 black, 15 brown and 15 white-coated dogs. Hochman-Elam, 2020 White coats let the most through, black coats the least, and shaving increased it. The 2022 hip trial even changed the light by coat colour.

• Part the fur: brush it apart over the area before you start.
• Clipping: a vet hospital says long dark fur "needs to be shaved (best scenario) or parted". CSU Veterinary Health, 2024 Clipping is a choice for you and your vet.
• Dark coats: they warm faster, so check the skin every minute or two.

When should you stop a red light session for your dog?

Stop as soon as the fur feels more than warm, or the dog gets up, pants, licks or turns to the spot, or seems unsettled. Never hold a dog in place, because being free to walk away is part of keeping it safe.

• Warmth: lay your hand on the fur every minute or two. Warm, never hot.
• Restlessness: shifting, whining or standing up ends the session.
• Panting: stop and let the dog move away.
• Licking or turning to the spot: stop and check the skin.
• Stay present: stay for the whole session; never leave the dog alone with the panel running.

How can you tell if red light is helping your dog?

Keep a short log before you start and review it with your vet every 2 weeks, giving it at least 6 weeks before deciding. In clinic laser therapy, change usually shows after 4 to 6 treatments, or 8 to 10 when several joints are treated.

That timing comes from vet guidance, which also notes that each patient responds differently. Huntingford, 2019 Log the arthritis signs surgeons list: how easily the dog gets up, walk distance, jumping onto the sofa or into the car, and sitting with a leg out. ACVS, 2024

Ask your vet about an owner questionnaire such as the Canine Brief Pain Inventory, which scores pain severity and how much pain interferes with normal activity. BVNA, 2022 In the study behind it, a drop of 1 point in severity and 2 points in interference counted as success. Fill it in before the first session and every 2 weeks.

Benefits can fade after sessions stop, which is why vets plan top-up sessions; a 2023 hip study kept monthly sessions during follow-up. Alves, 2023 Light does not replace medicine, and any dose change is the vet's decision.

How do you use the Kivorla panel for a dog at home?

With your vet's agreement, set the panel low on a door or upright on the floor, about 12 inches from the dog's body, in continuous mode with the visible channels turned down. Start with 2 to 3 minutes on one area and stay with the dog throughout.

The 9-Spectrum Red Light Therapy Panel is a 240 W half-body LED panel, used at a distance rather than pressed on the skin. It carries 480, 590, 630, 660, 670, 810, 830, 850 and 1060 nm, each dimmable from 1 to 100%.

• Timer: 1 to 30 minutes; it stops after 5 minutes if no time is set.
• Pulse: 1 to 10,000 Hz is available; keep it off for a dog.
• Surface: at or below 40°C.
• In the box: goggles, a controller, a door hook, a pulley, hanging cables and screws.

If the dog lies on your lap or beside you, you are in the light too: wear the goggles with your eyes closed. The panel's precautions for people then apply to you: not if you are pregnant, breastfeeding or preparing for pregnancy, have light-triggered seizures, have had sunburn on your body in the past 2 weeks, have skin type V or VI, or have a thyroid condition or take thyroid medication. Our precautions also rule out use with photosensitising medication, so check any medicine with your pharmacist or doctor first.
