Fecking nits and now fleas! My 8 month old chihuahua has fleas. I bought some frontline stuff from the supermarket, washed his beds and sprayed them with that expensive spray from the vet (I have had it a few years though). Nothing has worked. I need to sort this because he has scratched himself sore in one place
. Is the frontline that you buy from the vet different (ie stronger) than the supermarket one? Should I just bin his beds and buy new ones? We don't have carpets so no panic about them.
