Why does my dog ​​not lift its hind legs to pee recently?

The reason why my dog ​​has not raised its hind legs to pee recently may be because the dog is sick. Physical reasons may prevent the dog from lifting its legs to pee. For example, if there is a problem with the dog's hip joint, the elbow joint of the hind leg, or the dog's lumbar spine, it may cause the dog to be unable to lift its legs to pee. It is best to take your dog to the hospital for a check-up to see if it is due to a disease that causes the dog to urinate without rear legs.
