whatever heart worm medication you choose to use, please remember not to overlap it with comfortis. heartworm meds contain ivermectin which reacts in a negative way with the main ingredient of comfortis, which is called spinosad.

Finally went to my vets last Friday and discussed about the concerns of trifexis. Of course, he went on saying that there are always risks. I understood that, but it seems that trifexis is causing too much damage vs good here. Long story short, ace is on heart guard plus and nex gard (fleas and ticks). I'm a little concerned cause nex gard is fairly new. Any one have their bullies on this?
