Zorro has been having little leaks occaisionally. These often occur when he is barking about something -- wanting breakfast, wanting to go outside, etc. Today, he has had four accidents already, and it is only 10:00 am.
Incontinence is part of the pattern for what we suspect is Degenerative Myelopathy (or DM), a non-treatable, non-reversable disease that attacks the sheath surrounding the spinal cord in long-backed dogs. It is a sign that the disease is progressing upward, although Zorro still has some use of his rear right leg.
The first sign was the turning under of his rear left paw, which eventually became totally useless. His right rear paw is still able to help him scoot around as he drags his left.
I have added "doggie diapers" to my shopping list....
