It is not true, however. For one, it does not cause *anaphylactic* shock. The risk is from the dead heartworms being dislodged then causing a blockage, similar to an embolism.
Secondly, ivermectin is commonly used to treat dogs too unwell to undergo arsenic treatments, too difficult to keep calm, or dogs whose owners cannot afford the conventional treatment.
I would not use horse wormer for the simple sake that it's too easy to give too much or too little. I like the peace of mind that comes with a pre-measured dose, as heartworm isn't anything to be played around with.
