if u have commercial "bug men" like terminix in your area, i highly recommend it! it eliminated our flea problem completely. if you cant or dont have that option i would also like to recommend using a baby shampoo on your puppy, unlike using dish soap baby shampoo wont strip the puppys natural oils. doing so can also lead to itchy skin making you think he has fleas when its just really dry skin. just wet pup down, put a generous amount of baby shampoo (leave it a little thick) this smothers the fleas, and let it sit for 5 minutes, then rinse pup again for about 5 more minutes. i hope this helps! i was a dog trainer a a local petstore and thats what i suggested, and used on my dogs.
