Anyone use any of those Blue light or Red light therapy for treating arthritis in dogs?

My little buddy suffers bigly in the cold weather. Her right knee joint gets stiff and sore.

What's a good one that you have personal knowledge of. Under $250 if possible.

There are tons on Amazon and eBay but which ones are effective and worth the money?

Thanks
