I think we'll agree to disagree here Trevor - if you can tell me why 91 percent of the ingredients of Frontline are 'undisclosed' then I will reconsider my way of thinking
Also if you read the lengthy articles at the beginning of the thread you'll see that garlic and lavender are amongst many more natural flea control ways mentioned.
In the meantime I'll still fleacomb Jarv every day, and treat him with SMALL (which aren't poisonous) quantities of garlic and will endeavour to keep my flea and worm ridden dog away from small children (obviously he must be a risk since he's not preventatively chemically treated 'just in case' )
I can't tell you why they are undisclosed (I don't use frontline, I use Advocate) and I'm also not suggesting you should change what suits you or what you are happy with - I'm not sure why you think I am.
You're aware I've lost a dog to AI so as you can probably imagine, I have read an awful lot of articles and research on this subject and there is still no actual scientific, conclusive evidence in my mind. I'm sure there are reasons for limited research on this subject, the sceptic in me would say they are probably commercial ones.
However, there is another perspective to this which is all I've highlighted - if you are unlucky enough to get an infestation then it's an extremely unpleasant and longstanding issue to deal with and it has to be dealt with using a huge amount of chemicals AND spot on treatments. Another point to remember is that a LOT of dogs are treated with spot on treatments and live long and healthy lives. Whatever is said about garlic in that article, it's on the poison list from my vets and on countless other 'poisonous to dogs' list and as I KNOW it doesn't work for humans, it's unlikely to be really effective in a proper case of fleas, so I won't be relying on that or giving it just in case it helps
In the end it's personal choice and what is realistic for your family/lifestyle. Spot on treatments may not be for everyone and I didn't use them for years as I've already mentioned. However for us now, EVEN having lost a dog to AI, the 'risk' from spot on treatment is not outweighing the seriousness of a proper flea infestation or any other parasite problem in a home with a baby and young child. Agreeing to disagree isn't the point here I'd suggest. However, it is important to highlight other scenarios, as well as the fact that preventative treatments might possibly, in some cases have a negative health effect on the animal being treated - even if in most cases it doesn't.

ETA. Another unpleasant side effect of our visiting friends this year, was that both dogs got tape worm... which occurs when dogs eat fleas carrying tape worm eggs. This didn't happen until about 6 weeks into us first noticing the first fleas. It was a very long and drawn out process involving a lot of medication and chemicals to deal with all the fall out from a proper flea infestation. I know looking back that Dave picked them up from a dead rabbit, so it's not just contact with other dogs that you have to watch.
