Speaking of the danger to collies of Heartguard, our veterinarian is adamant
in his belief that it is not a danger to collies.  He told us that awhile
back there was a problem with some batch of the medicine being bad and
causing illness/death, but that it is no longer a problem.  He also said
that the other brand that is recommended for collies has used that scare to
promote its own brand among collie breeders.  He personally doesn't like the
other brand because it doesn't contain a certain ingredient that he feels is
needed for effectiveness (wasn't the ivermectin).  At any rate, he has given
the Heartguard to many collies and never seen any cases of problems caused
by it.  So I am not sure how to take this.  We had given our last collie
Heartguard, not knowing of the supposed danger, and he was never adversely
affected.  Anyone else know anything about it?
