Unfortunately it can be trial and error for pets or people about medicines. Hope she does better whatever you decide is best to do for her. That's all we can do is what we see in our eyes is the best thing. Trial and error.

Trifexis is a chewable tablet that kills fleas and prevents infestations - protects against heartworms - and treats and controls adult hookworm ..
