10 is an old dog, but it is unlikely to have iliac arthritis, because it is usually a disease of large dogs. Your family may be old. Do you have enough rice to supplement calcium in time? Old dogs are prone to calcium deficiency, so buy some calcium tablets or boil bone soup (a few drops of vinegar can help decompose). My friend's dog is fourteen years old and can hardly walk on its hind legs. It's all procrastination, so you should be mentally prepared. I hope you take good care of it. Although you are old, please make it happy in your old age.
