Decided to take Ellie back to the vet last night, she was still acting strange around her food, running away as if in pain when eating, well it turned out there is some good healing going on after all, her gums are a much paler pink and not nearly as inflammed, however Gabe said it was probably the right decision to take her back, as it could well be flaring up again and best to knock it out before that occurs, so he gave her an antibiotic jab and she is on steroid pill for fifteen days, so hopefully this will finally do the trick and Ellie will be all well again, fingers and all paws crossed here.
