Despite the cost, this was worth every penny. We have a 13 year old chihuahua and although he still walked and run, occasionally jumped onto the sofa, and climbed stairs to bed, it was becoming clear that there was discomfort in climbing stairs and ramps generally. Our vet said there was some discomfort in the middle of the back and both hips, mainly the left one, almost certainly osteoarthritis. The data on PEMF in humans is mixed, but AI actually suggested this device and presented data on effectiveness. The vet agreed and all I can say is that it's made a big difference to Luis. Honestly, after using the loop on both hips and the middle of the back for just two days he was already running on the beach for longer and running up stairs and ramps. After 2 weeks I've scaled back to just the left hip and back and the right hip every other day, and after another two weeks I'll dial it back again (this is all with AI guidance). It's important to get the area of concern within the center of the circular loop and not to have anything other than fur in front of it otherwise effectiveness is reduced). Really though, this has made a HUGE difference to our dog.
This was even more expensive for me because I still had to pay an EU customs charge despite the efforts of Zoomadog to help (and they were really helpful at every step) because I'm in Spain, but it wasn't substantial in reality. The loop was available from a seller on the Spanish Amazon website but I never trust whether I'm getting authentic products from third party sellers and the price was double the US price! However, it's worth every penny to us and our dog.
Anyway, I thought I'd add the detail to help those people living within the EU; I really recommend Zoomadog as a distributor.
