Frequently Asked Questions (FAQ's)
Are there side effects? Can I overdo it?
PawRay Pro™ uses gentle red and near-infrared light and is generally very well tolerated by pets when used as directed. You may notice mild warmth or temporary pinkness on the skin after a session—this usually fades quickly. If your pet ever seems uncomfortable, restless, or tries to move away, simply stop and shorten the next session.
Does red/NIR light work through clothes or fur?
Red and near-infrared light work best when they can reach the skin directly. Thick fabric or dense fur will block or scatter a lot of the light, which means your pet gets much less benefit.
For best results:
- Use PawRay Pro™ on bare skin whenever possible
- On furry areas, part the fur with your hand or gently rest the head against the skin
- Very thin fabric might let some light through, but you can test it by shining the device through the material—if you barely see the glow, your pet’s tissue won’t get much, either
Whenever you can, aim for direct contact or close distance to clean, dry skin.
Can I use it on an open wound?
Red and near-infrared light has been studied as an adjunct to support tissue repair and healing, and some veterinarians do use photobiomodulation on certain wounds as part of a treatment plan. However, because open wounds can vary a lot (depth, infection, bleeding, location), we strongly recommend using PawRay Pro™ on open wounds only under your veterinarian’s guidance.
In general, do not use it on heavily bleeding, infected, or unexplained lesions without a vet exam first, and always follow the wound-care instructions your vet provides.
How far should I hold the device from the treatment area?
For best results, keep PawRay Pro™ close to your pet’s skin so the light isn’t lost in the air:
- Ideal range: light contact or up to 0.5–2 inches from the skin
- You can gently rest the head on the area or hover just above it
- Avoid holding it more than ~6 inches away, as effectiveness drops quickly with distance
On furry areas, try to part the fur with your hand or use light contact so more red/NIR light actually reaches the skin.
What’s the risk to the eyes?
Like any bright light, you should never shine PawRay Pro™ directly into the eyes of your pet or any person. Red and near-infrared light can be helpful when used correctly, but direct exposure to the pupil/retina should always be avoided.
When you’re treating around the head or face, keep the beam angled away from the eyes and avoid pointing it toward them. We include free protective glasses in every order, and we strongly recommend wearing them yourself if the brightness feels uncomfortable or you’re working close to the face. For pets, simply shield their eyes with your hand or a soft cloth, and don’t use the device directly over the eye area.
What’s the benefit of having both red and near-infrared light in one device?
Red and near-infrared (NIR) light work in a similar way at the cellular level, but they reach different depths:
- Red light (~around 660 nm) mainly supports surface tissues like skin and the top layers around joints (great for skin, incision areas, and more superficial discomfort).
- Near-infrared light (~around 850 nm) penetrates deeper into muscles and joints, where a lot of stiffness and soreness live.
By combining both in one device, PawRay Pro™ can support surface and deeper tissues in the same session, giving your pet more complete coverage in a simple, at-home routine.
