Poor Baylee. There are panties made for the Whippet's slender bottom-
www.dogwalkers.net/index.html. Look under 'other stuff'.
Shelbie had a bout of incontinence. A few times she would dribble in her daybed and I would catch her licking herself frantically trying to clean herself up. Then she was dry for a while. A few days later, she went to take a catnap with my husband on our bed when she had a big time 'leak'. Luckily she was laying on a waterproof lap pad. She is also the type to claw through walls rather than to go potty in the house.
I talked our vet about it, he checked her for a UTI (nothing) and he said to mark the days she has these episodes and if it becomes more frequent, he'll give her estrogen.
In the meantime, her crate pillow is wrapped in plastic, covered by cloth and all catnapping on the big bed, her bottom is on the lap pad. So far, so good.

Yes, keep us posted about Devo. I worry about everybody's senior Whippies.
A dog's nose in the palm of your hand can cure almost anything.
