How it works
Low-Level Laser Therapy (LLLT) is a treatment that uses specific wavelengths of light to interact with tissue in order to help accelerate the healing process. Low-Level Lasers emit photons to stimulate cells to perform specific tasks in the body, such as reducing inflammation and edema, reducing or eliminating pain for a time, and speeding up wound closure.In essence, Low-Level Lasers like the Dog Med Laser teach nerve cells to stop the sensation of pain from reaching the brain.
Visible and invisible light is composed of photons. Lasers devices generate a beam of coherent monochromatic light by stimulated emission of photons from excited atoms or molecules. An example of the action of photons you may be familiar with is photosynthesis, the process by which plants use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Without light, there is no life.
The second example is tanning. The sun’s UV photons stimulate melanocytes (cells found in the layer of skin called the epidermis) to increase production of melanin (this is called melanogenesis) and, in turn, pigmentation.
As in nature, photons delivered by Low-Level Lasers stimulate the cells inside human and animal bodies to perform specific tasks, such as reducing or temporarily eliminating pain, reducing inflammation, and accelerating the multiplication of cells to close non-infected wounds faster.
The science of Photobiomodulation
Photobiomodulation is the strange scientific (and official) word for Low-Level Laser Therapy.
The use of this term is key, as it distinguishes photobiomodulation therapy, which is nonthermal (doesn’t generate heat), from the use of light-based thermal devices used for heating tissues using near-infrared (NIR) lamps.

FROM THE AMERICAN SOCIETY FOR LASER MEDICINE AND SURGERY
The Low-Level Laser DOG MED LASER is a true nonthermal laser using 635 nm red beam laser diodes generating a power of 21.5 milliwatts per diode with frequencies for better results.
635 nm red beams have been in use since the late 1960s and have been proven over and over again to be the best wavelength to deliver cellular stimulation and trigger cellular communication in order to generate positive results for inflammation and pain management and for acceleration of wound closure.
We at Dog Med Laser consider laser diodes to be the most efficient photon delivery medium to stimulate human or animal cells. Dog Med Laser diodes are expected to last many, many years, if used in a normal home environment.
The Myth of Power: Watts vs. Milliwatts
7,000 clinical studies have proven the efficacy of nonthermal Low-Level Lasers to deliver positive effects. Recognized institutions and publications have also vouched for the efficacy of Low-Level Lasers. These include the Wellman Center for Photomedicine at Massachusetts General Hospital, Harvard University, and MIT medical schools. Low-Level Lasers work by stimulating cells to do specific tasks. Cells are fragile organisms, and coaxing them to do work a certain way is tricky. Low-Level Laser photons’ delivery to the cells must respect a few principles in order to generate efficient results. One of these principle is recognized by the scientific community:
Not enough is not enough, and too much is too much.
That is in layman terms the translation of the ARNDT-SCHULTZ dose-response law.
Small doses of energy stimulate functions in living cells with no inhibition. Larger doses of energy initially stimulate, but if the doses increase, they start to inhibit cell functions. Very large doses of energy dramatically stimulate for milliseconds, and then dramatically (and for an extended time) totally inhibit the cells. The ultimate risk is cell death.
“Weak stimuli slightly accelerate vital activity; stronger stimuli raise it further, but a peak is reached, and an even stronger stimuli suppresses it until a negative response is finally achieved.” (Chow and Al, 2006)
The general consensus in the scientific community is that the Arndt-Schultz law applies to Low-Level Laser Therapy Photobiomodulation.
The study “Effect of Pulsing in Low-Level Light Therapy” from the Wellman Center for Photomedicine at Massachusetts General Hospital confirms that “the concept of biphasic dose response, or LLLT ‘hormesis,’ will remain.” This means low levels of laser lights are good for you, but high levels are bad for you.
Dog Med Laser technology respects the Arndt-Schultz dose-response law.
The Most Efficient Wavelength: Nonthermal LLL
It is proven that infrared wavelengths penetrate deep into tissue, but that does not mean that they are the absolute best. Below: Note the percentage of relative burn-healing after irradiation with different wavelengths: 633 nm is the clear winner (Al Watban et al., 2007). This is the what the DML produces.
The infrared wavelength uses the water chromophores, whereas the visible red 600-670 nm wavelengths uses hemoglobin. Low-Level Laser 635 nm generated photons are transported by blood to the cells that make up tissues.
Red 635 nm absorption spectra: oxyhemoglobin
Cells in animal bodies communicate with each other 24/7. This is called cellular communication. Dog Med Laser photon delivery frequencies are designed to stimulate the cells to specific tasks. Naturally, the stimulated cells send the task messages to similar cells, which in turn do the same to other similar cells, etc.
Some studies have shown, for example, that exposing one leg wound to red-laser photons accelerates not only the treated wound’s closure but also the closure of a wound located on the other leg that was never exposed to laser beams.
What matters most is not inches of penetration but instead correct cell communication stimulation.
J. Ty Hopkins et al. (BYU Provo, Utah) demonstrated in 2004 that exposing a patient’s wound to LLLT provoked a similar wound-closure pace in a nonexposed wound located on a different limb. And, at days 6, 8, and 10, follow-up testing revealed that the laser group had smaller wounds than the placebo group for both treated and the untreated wounds. This study demonstrated cellular communication in wound-healing processes using Low-Level Lasers.
We at Dog Med Laser believe that the undisputed efficacy of photons delivered by Low-Level Lasers similar to our Dog Med Laser will help your furry best friends live a better life as they grow older.
Photobiomodulation is the only treatment offering total safety with zero negative effects to your pet or yourself. We are not claiming to be the miracle cure for every pet on Earth. Some pets will react better than others. Keep in mind that you will not see instant relief in the majority of cases. Repeat treatments with cumulative effects are key to success.
It is definitely worth a try, and if you are not convinced, we offer a 90-day return policy.
