Received this on our IPDTA forum. ....
Just a note on Frontline & Advantage
according to the companies that make these products,
Bayer & Merial, these products are only considered
safe if purchased from a licensed vet.
They will not guarantee any product bought from
a pet store, online, etc. According to the reps
they have found that at least 70% of the OTC
product is counterfeit and comes from places such
as India & China. So even if it comes in look-alike
packaging it doesn't mean it is that product
As far as Hartz, Sargents, Zodiac & Bio-spot
have been long-time issues and still nothing has
been done. When asked why the only thing anyone
can seem to come up with is "they have powerful
lawyers" and "they help fund various programs".
I know many vets (sadly not all...) have info
posted in their waiting areas in regards to the
some have the dangers to cats but not to dogs.
OTC products (of concern) include flea collars,
topicals, powders, sprays and even shampoos.
