Unfortunately a lot of flea treatments – although effective – can stink to high heaven. However, although it's more than tempting to get rid of the smell and throw your dog in the tub the first chance you've got, it's best to wait it out.
Don't become confused with flea treatments labelling of 'Waterproof' – many customers consider this to mean straight after application and often bathe their dog. Allow the topical time to settle into your dog's skin before washing them or their protection will wear off sooner than you want it to. As a general rule of thumb, wait at least 48 hours before washing your four-legged friend.
One common error even seasoned dog-owners make is believing that the 48-hour rule only applies to topical medication. Unfortunately, there's no getting around the washing ban rule as it still applies – most collars will require the two-day headway to get their flea prevention going. If anything, it's a nice excuse to relax and not wash your dog for a while!
