You should always speak to a vet about black stools or persistent diarrhea. Black stools often have blood in them from high up in the digestive tract. Persistent diarhhea is often a sign of disease or parasites.

The package for the flea treatment should have instruction on it regarding when it is safe to bather the dog or let him get wet. If you don’t have the package, 3 days is usually sufficient to wait.
