Ankle support for dogs. This support corrects the ankle angle for dogs who have difficulty walking due to old age, etc., allowing them to walk more easily. (e.g., when the paw pads are facing backward and difficult to touch the ground) I think it can be used for small to medium-sized dogs. I used it on the hind legs of a 10kg Shiba Inu. It has Velcro, so the size can be adjusted to some extent. There are no instructions, but you should be able to fit it properly by aligning the rubber part that touches the floor with the ankle part, and then adjusting the ankle angle. Set of 2.
