One of my dogs has been fine in his cage for years at night. If he is left out of his cage he runs around outside and barks and keeps everybody up at night. If I try to keep him in his cage lately he does not stop until it is forced open. He often scrapes up and ies his head in the process. I was thinking of strengthening his cage but I do not want him to hurt himself, as he is 12 years old.
How do I stop this behavior?
Thanks in advance.
