Thornits is fine it has been in use by breeders for many years, you only use a pinch in each year once a month or so. I and many others have used it without any adverse effects, in fact i have
never heard of thornits causing any problems at all.
Be wary of taking everything a vet says as gospel i have pulled a vet up for miss prescribing medicine for Lucy and i am not alone! Some vets, and i'm not saying your vet or all vets, don't like thornits because a small tub costing £5 will last a year or two and there is no profit in it for them.
Modern veterinary medicines are far more potent than thornits and have a corresponding price tag, but thornits is not so much a cure as a preventative medicine. So as far as my opinion goes i would thoroughly endorse thornits and would question the wisdom of a vet who has never come across thornits
BTW thornits was in use as a dental antiseptic long before the modern day antibiotics where adopted.
Another recommendation if he is picking up grass seeds is to check Rupert regularly for seeds in his armpits and small lumps where they have got under the skin on the top of his paws, or between his toes. if you find one does get under the skin then Silica from boots homoeopathic range given one a day for a week will normally draw them out, but if it isn't sorted after a week then go see the vet. Don't ask me how homoeopathic silica works - as an engineer it would seem to be mumbo jumbo rather than a credible treatment but work it definitely does
Grass seeds are a real pain
