While constantly climbing up and down the stairs can be bad on any dog’s joints, it is okay for an adult dog to go up and down the stairs a few times a day. However, it is best not to let your Doberman puppy under one run up and down the stairs on his own. Puppies don’t just climb the stairs; they fly up and down them, resulting in injury. Any injury while your Doberman is still growing can be extremely problematic.
