my gordon setter had the same as your fcr,but his secondaires was in his throat he was only 5 years old,my vet did the same as your put the dog on a low dose of steriods,but it was the steriods that had other side effects which your vet shold of told you which effects the dog health,,in the end copper did live 6 months more with steriods,
i did go on a semiar run bye the kennel clud and lymphatic cancer was 1 of the subjects, if you go down the chemo it may only make the dogs life long bye 18 months,.again what the sised effect of that,the sma in humans the dog can not tell you if he under well plus the stress on going to the vets,for the treatment.
but at the end day each owner of dogs are diffeent in the way they want their dogs to be treated,there no rigth or wrong,it what you think is best for you and your dog,
good luck i know what you are going through,plus i got 5 fcr,the love of my life when they are good.
