What is Cold Laser Therapy?

Cold laser therapy, also known as low-level light therapy or therapeutic laser, is a wonderful, non-invasive way to speed healing and manage pain in dogs and cats. Actually, it’s even done for people, too! It was first cleared for use in Europe in the 1970’s, and finally cleared for use in the U.S. by the FDA in 2005. It’s very safe and has been very well-documented in hundreds of studies. We use K-Laser for our cold laser therapy, and we have seen great results and lots of wagging tails as a result.

How does cold laser therapy work?

It uses a specific wavelength of light (red and near-infrared) to stimulate cell-regeneration, increase circulation, reduce swelling and arthritic pain. It is painless and completely non-invasive. The effects of it are cumulative, so with each treatment typically lasting just a few minutes, the benefits begin to be seen after the first few treatments.

Cold laser therapy is great to accelerate the healing of wounds or other injuries and to help reduce chronic pain from conditions like arthritis and spondylosis. Because it can do this, it can help to reduce the amount of pain medication your pet might need. This is great news because the long-term use of some medications can become taxing on the liver and kidneys, so this indirectly helps to keep them healthy too.

What to Expect

Your appointment for cold laser therapy will be quick and easy. People in the exam room should wear protective eyeware, which is provided. Then your vet or technician will turn on the K-Laser and run it back and forth along the part of the body that is being treated for a particular amount of time that your vet determines is optimal. Usually, the entire appointment takes just a few minutes.

Initially, you may have two or three appointments within a week, but as the cumulative effects of the laser being to work, the frequency is reduced. Usually, within a couple of weeks, you can expect to be seeing good improvement in your cat or dog! After that, it’s just maintenance. You may be able to come in for treatment as little as once per month.
