Prevent bedsores in senior dogs who are bedridden or sleeping for long periods, and provide support for their joints. Also ideal for preventing chills. Large and medium-sized dogs. - Brand: Petio - Model Name: zuttone - Size: Large (14-20cm width, 12cm) I bought these to prevent bedsores for my dog who became bedridden and was kicking its legs, but it stopped moving its legs after using them on the front legs 2-3 times, so there are no pills or damage. 2 out of 4 are unused. Thank you for looking.
