I’ve been having good luck getting rid of fleas I find on Hoshi. I put Hoshi in his tub and wash his groin with a warm soapy cloth. It takes 10-20 minutes to wash and towel dry him.
I discovered fleas favor Hoshi’s genitals. That’s where I find them or flea dirt. Their speed makes them difficult to catch with a flea comb. I find baths work well on fleas but it’s time consuming bathing and drying off a long-haired breed.
The quick baths have been effective days and weeks later.
