<DIV>From what I have researched is that there are risks with either
method. The<BR>"fast kill" method of 2 or 3 injections kills the adult
heartworms fairly<BR>quickly. The risk is as they die off in pretty
significant numbers there is<BR>a risk of pulmonary embolism from the dead and
dying worms. That is the<BR>reason dogs are kept very quiet for 6 to 8
weeks. The problem with having a<BR>dog who "freaks" when being confined
is that it defeats the purpose of<BR>staying calm - a stressed dogs heartrate
increases thus increasing the risk<BR>of the pulmonary embolism.<BR><BR>With the
slow kill, the adult worms have a normal life span of 2 to 5 years.<BR>They die
off naturally, but prior to dying off they are grown and<BR>potentially damaging
the heart and lungs. Less chance of pulmonary embolism<BR>because the
worms don't all die at once as in the fast kill, they just die<BR>off at
different intervals. Plus by adding Doxycycline it kills off the
Wolbachia:</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Here's info on that:</FONT></DIV>
<DIV>Recent research has led to the discovery of a parasite called Wolbachia
that lives symbiotically inside heartworms. <B>Studies indicate that this
parasite contributes to the adverse effects of both heartworm infection and
heartworm treatment, including inflammation, embolism and allergic reaction.
Treatment with doxycycline to kill the Wolbachia parasite weakens the heartworms
and makes them unable to reproduce, lessens their adverse effects on the body
and greatly reduces the chance of adverse reaction during heartworm
treatment.</B> <BR><BR>By giving monthly, or weekly doses of heartgard we are
killing the eggs so<BR>they never become adult worms that travel to the
heart.<BR><BR>Either way presents major risks apparently. So I am just
seeking what has<BR>worked for you all.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>AND is there a test, or ultrasound, or something to
see just how many heartworms are actually in Hamilton (YUK to even think about
this :(</FONT><BR></DIV></BODY></HTML>
