Ah, well, see - I learned something new today! I had no idea some dogs require this much bathing. Perhaps it's related to the type of shampoo then. Switching types may be the difference between flakey, dry skin and nice, moist skin.
Please keep us up to date on how your dog is doing.
I'm firm - but fair. Mind the rules and enjoy your stay.
According to the Humane Society of the United States:
There are an estimated 3-4 million dogs and cats euthanized each year in the US alone! PLEASE - spay and/or neuter your pets!
