Me and my dog really had a terrible summer ... constantly had to be interrupted the game, or walk, because these pesky fleas! I really have tried everything ... Frontline - expensive and helped only a little Floo Powder - can forget! Flea collars - stink horribly and not really help Going for a swim - helps briefly and then this shampoo - fantastic! It has a pleasant odor, can be very well spread and really helps! It should however be already repeated again after some time. I bathe my dogs right now so that when I notice an increased scratch and of course should the ceiling and bedding, carpet etc. Anyway eg be cleaned with a steam cleaner - who has not, a steam iron also fulfills its purpose ;-)
