Replying to a message of Richard Webb to all:

 RW> tHey say in this little note:  "We have had an unacceptable
 RW> number of dogs test positive for heartworm that have been on
 RW> pone of the preventatives listed ... "

One has to wonder how they define 'unacceptable.'  When I lived in Plattsmouth,
the local vet had a map of the city posted on the waiting room wall - with push pins
stuck in it to indicate the locations of heartworm infected dogs.  There were a bunch
of such pins - including one at my house as one of my dogs contracted heartworm and
it cost me right about $500 to get him cured.

 RW> OF course heart guard is listed.

 RW> When querying our vet's office about this yesterday, we were
 RW> told the following:

 RW> IF we were to switch to this new formulation we could remain
 RW> on our monthly regimen.  HOwever, we'd still need to treat
 RW> with the frontline for tick control.

 RW> HOwever, if we don't switch then we should go to an every
 RW> twenty days cycle for the heart guard.

 RW> Anybody else hearing this?

The only thing I hear from my vets is a reminder when shots are due.
