She was spayed yesterday and i've just seen a flea hop on to her bald patch. I killed the flea and i've brushed her all over with a flea comb and i've not found anymore or any flea eggs. Is it possible for there to just be the one or will i need to get her some flea treatment now? She is going back to the vets tomorrow for a check up (i was shocked they wanted to see her again so soon) so i will ask their opinion too but just wondered what anyone on here thought? If she does need to be treated for fleas i was going to get effipro spot ons as i know my mum uses these on her 2. Is this a good one to get? I'm hoping the vets wont charge too much for it!
