cold laser for dogs

Some of best testimonials for the use of cold lasers are in the veterinary field and companion care. There is no possibility for a placebo effect with animals so when an animal is treated with a cold laser and then they return to normal behavior; it is obvious that the therapy is really making a difference. The requirements for veterinary use are different from the requirements for home use lasers, office lasers or equine lasers. This is a guide for use of cold lasers for vets and companion care, especially laser therapy for dogs.

FDA Requirements

The FDA does not regulate cold lasers for use on animals. This means that users are free to buy either an FDA cleared devices or lower cost non-FDA devices. Just be careful because non-FDA lasers may have lower overall quality standards. Companies that don't have the organization or funding capabilities to get FDA clearance, often have other problems too. They might have fabricated specs, be illegally smuggled systems or just be a laser pointer or flashlight that they call a therapy device. These companies might also disappear if you need support. When comparing lasers, make sure you match up the specifications and include construction quality as well as the other factors to determine if it is a good value laser or just worthless junk.

With a few exceptions, anyone can buy any cold laser for animal or companion care.

In veterinary care, there are 2 types of treatments

Broad (Tissue, Skeletal, Joint and Ligament) Therapy - Treating structural injuries and broad areas of damaged tissue is typically done with a large diameter emitter. Cold lasers for this application usually have a treatment diameter the size of dime to a silver dollar. Class 4 lasers, over 5 watts, use a laser module and a fiber optic cable to get the energy to the emitter head. Below 5 watts many manufacturers use multiple laser beams to get a combined treatment area. In general, laser below 100mW can take a very long time before they produce a no tic able difference in an animal.

Trigger Point or Acupoint Therapy - In trigger point and acupoint therapy, a smaller diameter emitter is used to excite an area of the animal's body that will trigger a systematic reaction. These probes have a max power level of 500 mW. Probes with less than 50 mW are probably underpowered and increasing the power of a pinpoint beam to more than 500 mW would only make it more dangerous. If you are treating small animals including small dogs, cats and hamsters in this type of format, it may drive your selection process and you may want to read our guide to acupoint and trigger point therapy, for extended information. Of course, if you have a broad treatment laser, you can use it for treating acupoints and trigger point by just resetting the entire area. This might not be precise enough for some practitioners but it is a common practice.

Some systems have options for both types of emitters or they sell an option to safely concentrate the output from a larger emitter into a pinpoint.

Power, Wavelength and Pulsing

In general, we make recommendations for systems based on our golden rule for maximum efficacy.

Veterinary cold laser efficacy is based 60% on the power level (or dosage), 20% on wavelength and 20% on pulsing frequency.

Power: The power controls the dosage and the dosage is the key to success. Too low and nothing happens, Too high and you get maximum pain relief but not the optimum healing. Higher power lasers will provide a higher dosage in a reasonable amount of time and that will provide more noticeable results. Many smaller dosage should provide better healing but the change will not be so dramatic. Many pet owners do not have the patience to handle many smaller dosage so a more powerful system is required to provide more immediate results. (Read more about power requirements for lasers)

Wavelength: Since the wavelength determines the depth of penetration, selecting the proper wavelength is critical. There is NOT one perfect wavelength for every application but studies show that 800 to 860nm is the best option for most therapies. For some applications (like superficial damage, abrasions, hoofs and cuts) Red (635nm) is the better wavelength. 905nm also provides good efficient energy transfer to the cells and deep penetration. In general, 980nm systems are extremely low efficiency. Most of the power is absorbed by the water in the tissue. This will increase circulation in the area but 980nm systems are not the best option for the animal. (Read more about different wavelengths and how they have different interactions with the tissue)

Pulsing: In general, the consensus is that pulsing is better for most application and continuous wave is best for rebuilding nervous system damage (*See Study Here). Pulsing the laser adds additional benefits by stimulating the cells. In addition, pulsing the laser helps keep the body from adapting to the input. The human body adapts to fixed inputs (like wearing clothes) and our bodies can react less over long periods of time. The same theory can be applied to lasers. This means that people with chronic problems that require long-term therapy might start to see declining results with a CW (Continuous Wave) fixed output laser. Based on current technology, we recommend buying a laser that does both pulsing and continuous wave output if it is within your budget. (Read More about pulsing and CW advantages)

For advanced users that will be treating a wide variety of conditions, a multiple wavelength, pulsing, and continuous laser with lots of power is the ultimate. If you just want a "point and shoot" laser, that will help your veterinary therapy without having to spend a lot of time on setup, buy the product with the most power that you can afford. If you must compromise focus on wavelengths, but make sure you get enough power. Consider pulsing as a second priority.

Selecting A Laser

There are many great options for cold lasers for companion care and veterinary applications. In most cases, the big decision is whether to buy a class 4 system or a lower power system. Class 4 systems are the best option for any one with a significant volume of animals to be treated. If you are only treating 1 or 2 animals per day, you might still want but you do not need a class 4 system. The following laser are all great for veterinary and companion pet therapy.

Using the Laser

One of the last critical areas to consider when buying a system is the level of training that comes with the laser. Many systems from other sellers do not include adequate training on how to use the laser on pets and horses. Every system that we sell includes the animal protocol library (You can see all the available protocols here). The laser-therapy system dynamically calculates dosage based on key factors like the size of the dog and color of the dogs fur. If you are using a printout of other statically created protocol, you need to get your calculator out or your your dosage can be horribly wrong. Size, fur color and therapy objective have a huge impact on selecting the best dosage for the best results. This is especially key for anyone who does not have experience using a laser on an animal. When you purchase any animal laser from, we include the information that you need to properly treat animals using the current best practices.
