<human>: I have two small dogs, and both are recovering from fleas right now (Fleas are gone but theyre dealing with the left over bites, itchiness, soreness, trauma from all the flea baths and treatment and the unfamiliar chemical smells around the house and on them. The poor things are obviously miserable and uncomfortable and not themselves) 

My little poodlely mutt was previously abused, but normally she is very loving and trusting of us, despite occasionally flinching and cowering if we approach her incorrectly. But since the flea treatment shes been acting like an abused, wounded animal, and looking at me in particular as though I caused her all the pain and disconfort shes experienced these past few days. Shes completely untrusting now, like when we first adopted her, but still will curl up in my lap and fall asleep. 

Tonight i let her out, and after much coaxing to come back inside (not normal) she cowers and slouches back in, tail between her legs, and looks me in the eye and clacks her teeth. 

Ive never seen anything like it, and i dont know what it means. As I type this shes asleep at the foot of my bed, but I cant help but be unnerved by this.

Give me a shortened version of the text
<bot>: Dog is recovering from fleas and clearly blames me for her discomfort. Suddenly became untrusting and clacked her teeth at me. Color me confused.
