I almost started my dog on trifexis but there was to many negatives for me to justify giving it, I would rather deal with fleas then worry if my dog might be the one to have a negative reaction with Trifexis. Straining can and has caused small of blood in my dog. Have they tested for Lepto? How about any toxins?
