Before you treat your dog for fleas - be sure he has them.
My vet combs through a dog's hair with a fine flea comb several times and then bangs the comb onto a white counter. Wish I could remember for sure, but then I think she sprayed water on the that area - and said that fleas will show up if there are any.
Also - when one of my dogs had fleas years ago - we could see them - and when we held or petted the dog - the fleas bothered us too. No fun!
