Thank you for viewing. I purchased this in September of this year and used it for about half a month to help my dog maintain a proper posture while eating. My dog is a Toy Poodle, and I used it when he weighed 1.5kg. Although this is just my amateur assessment, I don't see any noticeable damage. I've borrowed the images from the purchase site. The actual item has been disassembled, so I haven't posted any pictures, but please let me know if you need them. The parts that come into contact with the body have been home-cleaned. I hope this will be helpful if you are considering a wheelchair for the first time. Please consider this only if you understand that it is a used item. #DogWheelchair #DogWalker #NursingDog #SeniorDog
