Why do dogs like to pee in bed?

First, the owner didn't teach the dog to urinate regularly, so the dog will urinate indiscriminately. It is suggested that the owner can train the dog in about 2-3 months. Second, there is a problem with the dog's urinary system or the nerve center that controls urine, which leads to uncontrolled urination. It is suggested that the owner observe the urination of the dog and take the dog to the hospital for examination in time. Thirdly, the dog wants to attract the owner's attention in this way, or the owner has done something to cause the dog's emotional change, which leads to the behavior of peeing in bed. The owner needs to know the reason first, and then take corresponding measures for the dog.
