This tenant was absolutely horrible - in both their communication style and behavior.

Do you really want to punish that behavior?

But, with this tenant, if they know they're supposed to call you first, and they aren't, you need to stop this bullying behavior. 

Your behavior has trained the tenant as to what is acceptable.

Some others are: pardons based on new evidence that exonerates; pardons for political reasons or good behavior; unadjudicated matters that are still within the statute of limitations for the offense; unadjudicated matters that are now beyond the statute of limitations for the offense. 

Did the tenant display disruptive behavior?

If the breed of the animal means you can lose your insurance, then you can deny the animal - or rather their request for a reasonable accommodation - based on the request creating a financial hardship for you.But, since you've already allowed it, now your easiest way to get rid of them is to start giving them warnings based on the animal's behavior. 

Your behavior changes the lease terms.  

Then, you would be even more restricted as far as acceptable grounds to evict her, from my understanding of Section 8 rules.Your best bet to getting her out before November, would be to start documenting her behavior and giving her written warnings - but it would have to be behavior that is something you can evict for.Did the police come?  

I know the holidays can be a tough time of year for folks, especially perhaps RE agents given the year we've had with lower transaction volume.I'm going to assume there's also a good chance you're going through some personal stuff that would explain the behavior.
