Cold laser therapy has been used in veterinary medicine and alternative wellness for over 30 years. It is referred to as a cold laser because it does not use heat, instead it uses UV light which depending on the class level and diodes may reach 5-6 inches deep into the soft tissue. Cold laser therapy is used primarily to target specific areas of soreness, knots, or injury to bring healthy blood flow to an area and reduce inflammation at the cellular level. Most humans cannot feel it, however, animals are extremely sensitive to it and often will reveal muscle spasms and move either into, or away, from the handheld device.

When To Use Cold Laser

There are many grades of cold laser. I use a Class 3B laser to search for remaining sensitivity after a bodywork session, to soothe hot spots and help knots unravel without creating soreness. This device is primarily used to target deep tissue, while red light therapy a much different device, is should for wound healing and topical issues like cuts and bruising.


Cold laser therapy is generally considered safe and is often used with protective eye wear because of the UV aspect.

  • Avoid looking at the light directly. Dogs should wear protective goggles if using near the head.
  • Do not use on pregnant animals.
  • Do not use directly on cancerous tumors or undiagnosed cysts.
  • Do not use on thyroid.
  • Do not use on areas of active and profuse bleeding.

Why I Use Cold Laser

Cold laser therapy is a safe, gentle and effective tool to build on bodywork sessions. When used properly, it can highlight areas of sensitivity, decrease swelling and inflammation, prevent muscle soreness, and much more. This therapy is not a replacement for veterinary care, soft tissue bodywork with both horses or dogs, or chiropractic care. As a result, this is offered as an add-on rather than a standalone service.
