Stopped eating

Hi guys really worried Neala has stopped eating ,,she went off it a bit when she was in season in November but soon got back to it ,,however the last couple of weeks ,she has hardly eaten a thing, she is on raw ,same as the boys ,they get the usual,,carcass beef, tripe, lamb ribs ,eggs fish etc ,and i have been through nearly everything ,tried the 10 min rule ,,eating seperate etc
she seems happy in herself and will take a treat if offered
so what else do i try ?? or is it the vets she has always had a good appetite so just seems a bit strange , wallace used to be fussy till i discovered he likes to eat on his own without anyone watching lol strange boy any help/advice
I am worried xxx

Phantom????

maybe try boiled chicken or scrambled eggs. my dogs love cottage cheese and green beans which is usually given if a dog needs to lose weight.
