I have been giving this to my small mixed terrier for years with no I'll effects. With everything I'm reading about it being poison, I wanted to switch her off of it to heart gard and some other flea med. I was giving comfortis for a long time but it seems it gets reviews just as bad as trifexis. I'm seeing mostly bad reviews and it was good to see someone who's dogs do okay with it. Still confused what to do. I gave her the last dose in the box this morning with her breakfast and she has been running around and playing. She is 8 years old too!
