There is pet deodorant spray that you can spray on the dog. My one kitten came from a home that treated him badly and he stunk badly like a litter box. Washed the poor kitten 6 times even with deskunker and couldn't get the smell out.
Finally, I bought a pet deodorant spray. The kitten smelled like peaches and litter box for a day (yuck) but the next day the kitten had the baby kitten smell and nothing else.
