I too saw that and it's something I've been mulling over and will be looking into more. In an ideal world guinea pig only products probably should be first port of call, what worries me is what someone is to do when a) the vet is useless and won't listen to owners suggestions, and b) the pigs have to wait 2-5 days for the postman to bring their treatment. There's a gap during which time the pig is still suffering.
I advise in line with CCT, some other rodentologists and my own experience. I wouldn't advise something that has been proven harmful to pigs. I've heard someones experience of pigs being burned by spot-on ivermectin treatments yet these treatments are still widely recommended. Individual pigs circumstances do have to be taken into account - I wouldn't advise using spot-on treatments on pigs with broken skin, for example, and I have recently discovered I wouldn't advise using a human anti-fungal med on pigs with broken skin, rather something like Aloe Vera until the lesions have scabbed over and/or something from GG if they can get hold of it.
Like baby products, some parents swear blind that most shampoos containing certain ingredients are harmful and will damage their children, it's their opinion and personal preference while others use the 'harmful' stuff without problems - there's nothing wrong with either choice. My first choice is GG for some things but I do trust other people and have had success with human products as well, what I want to know is if it can be proven that certain products have led to problems in pigs or if actually, as a short-term treatment or even as the whole treatment if it proves effective, human products will prevent suffering in the pig when there are just no other options.
It's not a case of replacing animal treatment with human treatments for guineas, it's providing a stop-gap for people who have vets who can't/won't help, and who can't afford or afford to wait for what some people consider the best treatment for them.
In my view there is room for both and people should be allowed to make their own choice, but yes the vet should be consulted whichever way.
