My dog after 11 years has fleas for the 1st time we’ve Used Advantage spot on for her but now looking for something we can use on the lounge carpets. My Chilean Rose has just moulted and my Nicaraguan Curly Hair is in pre-moult so I don’t want to chance moving either of them just now. Any recommendations on t-friendly flea treatments please? Don’t mind if it’s spray or powder, as long as it’s effective and won’t hurt my 8 legged babies!!!
