Ranchers, breeders, some pet owners, my vet, and another member's vet said they can be treated topically with tinaction or another antifungal over the counter powder.. I called my vet earlier today and asked him about the tinaction, or other antifungal powder and he said it was absolutely fine to use in moderation. They are not breathing it in long term, and it is only a teaspoon to one cup of dust. He agreed that he finds it no more harmful than breathing in regular chinchilla dust, especially blue cloud since it is so fine.
Dr. Brown also said all these chins NEED a wellness vet visit right away, which I do not agree with. If my chins are showing signs of having a problem they will go to the vet. Until then, I know their teeth are fine because they are orange and they are eating like crazy. don't need to pay a vet to knock my chin out, look at the teeth, and tell me what I already know. Their poos look great so I am assuming there is nothing going on in their gut with parasites, or otherwise. Unless you are doing bloodwork (which vets usually do not do for wellness visits because their veins are so tiny) or something like that, I don't see what a wellness visit will do other than stress out these stressed out chins even more. I have taken a chin for a wellness visit. It was literally a vet who looked at their poo, their teeth and looked over their body. That's it. I can do that at home. If they do start showing any signs of their being a problem I will bring the chins to the vet ASAP. I have absolutely no problem with that.
And to anyone who thinks that I am one of the people who just doesn't want to pay for a vet visit, you are wrong. I have taken two chins to the vet 3 times in the last two weeks, and I just paid for surgery for one, and to have another chin knocked out and his teeth checked for another. I have absolutely no issue what-so-ever with paying for a vet, when it is needed.
It probably isn't the same type of fungus as ringworm. But, I would pick one type of cream or another.
