yes that is it, Hibiscrub!

I just feel so bad for him as it cannot be pleasant. he does get a biscuit after so I hope that softens the blow a bit for him.
I dont know whether he will need any ops. If he does he is insured so it will be ok and I will just go with what the vet suggests. As you say in a way it solved honey's problem so it may in the end be the best solution for Hamish too. he does not smell bad actually but maybe we have caught it early. it also worse on the left side than the right for some reason.
four months seems a long time but I guess he will get used to it and be less scared the longer it goes on. Poor lad

thanks for all your support and I will keep you updated. he has a follow up at the vets on 19th feb.
