Red light for dogs · Buyer's guide

Before you buy a red light for your dog, check these 5 things.

They all look the same in the photos. These 5 quick checks show you which ones are worth your money.

  • No shaving, it works on the coat
  • A timer and a battery, so you use it daily
  • A real refund window, 90 days or more

Yes, we make one of these. So we hold ours to the same 5 checks. Judge it for yourself.

Check01

Does it list both kinds of light?

Good wands use two kinds of light. Red light (650nm) works near the surface. Near-infrared light (808nm) is a longer wave that goes deeper, through the coat.

Clinics use both. A lot of cheap wands only have red.

Check02

Does it tell you how strong it is?

Power is shown in mW. More power means more light reaches your dog in each session.

If a seller hides this number, there is usually a reason.

Will it work through his coat?

You should never have to shave your dog. Near-infrared light passes through fur.

Part the coat and hold it on the spot. That's it. No gel. Nothing to wipe off after.

Will you really use it every day?

The best wand is the one you actually pick up. A cord, a loud fan or a warm head all make you skip days.

Quick answers

Still deciding?

How is this different from a cheap red light?

Most cheap ones only have red light (650nm), which stays near the surface. This one adds 808nm near-infrared, which goes deeper and through the coat. It also lists its power: 660mW total. If a wand does not list its wavelengths or power, that tells you a lot.

Will it work through thick fur?

Yes. That is what the 808nm light is for. No shaving and no gel. On a very thick double coat, part the fur a little and hold it on the spot.

How often do I use it?

You set each session from 5 to 30 minutes. Most owners do one or two a day. If your dog is under a vet's care, follow their advice on how often.

How soon will I notice a difference?

We won't promise a timeline. Every dog is different. Owners tell us they watch how their dog gets up after a nap and how they handle the stairs. You have 90 days to decide.

Is it safe? Does it get hot?

It never gets warm. The one rule is eyes: wear the goggles in the box and never point it at anyone's eyes. Ask your vet first if your dog is pregnant, has a tumour, a seizure history, an open wound, or takes light-sensitive medicine.

How does it compare to the vet's laser?

Clinic lasers are stronger, and trained staff run them. This is the same two kinds of light in a wand you own, so you can do short sessions at home whenever you want. If your vet set up clinic sessions, don't cancel them. Ask if home sessions fit alongside.

Can I use it on more than one dog?

Yes. There is no limit on sessions, so one wand covers every dog in the house.

What if my dog won't sit still?

Start with one minute on a spot they like being touched, during something they already enjoy. It makes no noise and no heat, so most dogs settle in. If yours never does, that is what the 90 days are for.

What's in the box?

The wand, safety goggles, a USB-C charging cable, a zip-up case and a quick-start guide. A free Joint Recovery eBook comes by email.

How long is shipping?

Free to the US and Canada, with tracking. Most orders arrive in 8 to 12 business days.

Is the guarantee real?

Yes. 90 days from delivery, full money back. Email support@wagwize.com with your order number. Plus a 1-year warranty on defects.
