At WellsCare, our mission has always been to make proven, non-invasive pain relief more accessible—whether it’s for muscle recovery, joint pain, or everyday discomfort. While IASO was originally developed as a compact light therapy device for human use, a surprising new trend has emerged in Korea: pet owners are using IASO for their animals—and loving the results.
This growing interest has led us to take a closer look at how IASO’s low-level laser therapy (LLLT) might be supporting our four-legged friends.
IASO PET: A Growing Trend in Korea
In Korea, we’ve seen a strong uptick in pet owners using IASO for their dogs and cats, especially those dealing with joint problems or recovering from injuries. So many customers were using the product this way that we officially launched IASO PET, a version of IASO introduced specifically for animal care. The response? Overwhelmingly positive.
While IASO PET has not yet launched in the U.S., the standard IASO device uses the same red and near-infrared wavelengths (650nm and 830nm)—technology that is already being used in veterinary clinics and pet rehab centers worldwide. The only difference is packaging and positioning. In other words: yes, IASO can be used on pets, and many already are.
Pet Owners Share Their Experiences with IASO
In Korea, pet owners have been sharing a growing number of stories about how IASO has helped their animals—especially older pets struggling with mobility or joint discomfort. One customer noticed that their 14-year-old Pomeranian, who had trouble walking due to stiff back legs, began to walk more steadily after about a week of daily IASO sessions applied with a soft wrap. Another pet parent observed that their Chihuahua with chronic hip issues seemed more active and less hesitant after using IASO post-walks.
There are also reports of small breeds with patellar luxation—a common knee condition—showing signs of reduced limping and more confident movement after consistent use. Many of these pet owners had previously relied on medication alone, but added IASO as a gentle, non-invasive complement to their care routine.
From everyday households to passionate pet bloggers, Korean customers continue to document the ways IASO is bringing comfort to their furry companions. These real-life examples highlight how low-level laser therapy may offer meaningful relief when used thoughtfully and consistently.
How It Works: A Quick Recap
IASO uses low-level laser therapy (LLLT), also known as photobiomodulation, to deliver light
energy deep into tissues. This stimulates cellular activity, promotes blood circulation, and reduces inflammation. The technology has been widely studied and used in both human and veterinary settings.
Because IASO is wireless, lightweight, and easy to apply, it’s particularly suitable for at-home care. Pet owners can simply wrap or hold the device gently over the area of concern for about 30 minutes per session, up to three times a day, as recommended. This makes it easy to incorporate into your pet’s daily routine—whether it’s for managing chronic discomfort, supporting recovery, or simply providing a moment of relief.
⚠️ Important: Always consult with your veterinarian before starting any new therapy for your pet, especially if they have a medical condition or are recovering from surgery.
IASO and the Future of At-Home Pet Care
As interest in at-home wellness solutions continues to grow, more pet owners are exploring new ways to support their companions’ comfort and recovery. IASO, with its gentle light therapy and easy, hands-free design, has naturally found its place in some pet care routines. Originally designed for people, it’s now quietly expanding its role in everyday care—showing that healing at home can go beyond just human use.
