Wouldn’t it be
better to focus your efforts on treating dog
fleas that are already there, since that
would eventually cut the population count to
zero? Short answer: no.
If the extent
of your flea elimination plan is killing as
many fleas as you can, then you’re doomed to
frustration. You’ll likely keep at it for a
while, wondering why the flea problem keeps
getting worse despite your best efforts.
Eventually, you’ll give up, submitting to
the unfathomable superiority of the filthy
parasites sucking your dog dry.
