Hey...Someone seems to be in the wars at the moment..(poor little one)..
I would have thought here that it could be connected to the fleas,strange as it sounds the flea treatment will work and kills the buggers off but your little one,could well be alergic to the flea bites,hence the licking and 'nasty red spots'....
I think it would be wise to go to your vets and discuss when the problem/s started and see what he/she says,
Red spots can be very nasty,cause they itch,so what do you do?...well you scratch em and we go round in circles,
Hope to here all goes well for you.
