Laser therapy for pets: what it is and who it helps


By Paws & Claws Animal Hospital • October 20, 2026

If you have ever watched an older dog take the stairs one careful step at a time, or noticed your cat has quietly stopped jumping onto the windowsill, you know how hard it is to see a pet slow down. Laser therapy is one of the tools we use at Paws & Claws to help with that, and it is probably the service we get the most "wait, what is that?" questions about. So here is the plain version, no lab coat required.

What laser therapy actually is

The fancy name is photobiomodulation. The short version is that we use a handheld device that shines a specific wavelength of light into sore or healing tissue. Cells absorb that light, and the current understanding is that it nudges them to produce more energy, calm inflammation, and improve blood flow to the area. Think of it as giving the body's own repair crew a bit more to work with, rather than sending in a new crew.

It is not the kind of laser used in surgery. Nothing is cut, nothing is burned, and there is no sedation. Your pet feels a gentle warmth and that is about it. Most of our patients lie still for the whole thing, and more than a few have dozed off mid-session. Everyone in the room wears protective goggles, including your pet (yes, we have doggles, and yes, you can take a picture).

What we use it for

We reach for laser therapy most often with these:

  • Arthritis and joint pain. Stiff hips, sore backs, and creaky elbows in senior dogs and cats. This is our most common use by far.
  • Healing after surgery. A few minutes over an incision can help the area settle down and heal comfortably.
  • Skin and ear trouble. Hot spots, lick granulomas (those stubborn spots dogs will not leave alone), and inflamed ears.
  • Slow-healing wounds. Scrapes and sores that just are not closing the way they should.

Cats get a lot out of this too, which surprises people. Cats are experts at hiding joint pain, so instead of limping they just do less: fewer jumps, shorter grooming sessions, more time sleeping in one spot. A quick, quiet treatment they can have while sitting in a towel on the exam table tends to go over much better than you would expect from a cat.

What a session looks like

It is a little anticlimactic, and we mean that as a compliment. You stay with your pet the whole time. One of us moves the laser slowly over the sore area for a few minutes, your pet gets some ear scratches and maybe a treat, and you are on your way. There is no shaving, no needles, and nothing to do at home afterward.

How many sessions depends on the problem. A short-term issue like a healing incision or a hot spot usually gets a handful of treatments over a week or two. Chronic arthritis typically starts with a series of sessions close together, then tapers to a maintenance visit every few weeks or whenever your pet seems to need a boost.

What it can and cannot do

We want to be straight with you here, because this is a topic with a lot of hype online. The research on laser therapy for pets is encouraging but still fairly small. Some well-designed studies have found that arthritic dogs treated with laser moved more comfortably and needed less pain medication than dogs who got a sham treatment. That is why veterinary pain guidelines, including those from the American Animal Hospital Association, describe laser as one piece of a bigger plan rather than a cure on its own.

So in our exam rooms, laser therapy lives alongside the other things that help a sore pet: keeping weight down (every extra pound lands on those joints), appropriate medication when it is needed, joint supplements where they make sense, and simple changes at home like rugs on slick floors, a ramp to the couch, and a lower-sided litter box for an older cat. Laser often lets us lean a little less on medication, which is a real win for pets with sensitive stomachs or kidneys.

There are a few situations where we skip it, such as over a known tumor or in a pregnant pet, and we will always check your pet's history first. It is not a replacement for figuring out what is actually wrong. If your dog is suddenly limping, we want to examine the leg and maybe take an X-ray before anyone points a light at it.

Is it right for your pet?

If you have an older dog or cat who is slower to get up, hesitates at stairs, or has stopped doing a favorite thing, that is worth a conversation. Pet owners around Nashville often chalk these changes up to "just getting old," and sometimes that is true. But often it is pain, and pain we can do something about.

You can read more on our laser therapy page, or just request an appointment and ask us about it at your pet's next visit. We are happy to show you the device and talk through what we would expect for your pet. Your pet's couch-jumping career may not be over yet.
