I used to recommend Heartguard Plain chewable rather than Heartguard Plus as it only has ivermectin in it, rather than all
the added poisonous insecticides that are not needed on a monthly basis.
Now, they are not making it anymore and I have been asked over and
over again what should be given in place of this.
An industrious client of mine found the perfect substitute that is over the counter and very
inexpensive and also effective!
