Just wanted to let you know that you aren't alone!  I don't have any words of wisdom - I'm figuring this out as I go.
  
 We've had Sucre for 2 weeks now, and we're still working on the aggression issues.  This is his 3rd home.  He was abused and exposed to drugs, so I have my work cut out for me.  
  
 I'm glad to hear you are making progress.  
  
 We're having a little showdown tonight.  I've been home all day, but had people here working on my satellite / internet, and I've been really busy cleaning, doing laundry and hand feeding 3 lovebirds and a parrotlet.  I still don't trust Sucre enough to let her out when I am not keeping a close eye on her - I have 2 small dogs and she really has it out for my Chihuahua, and I didn't want the people working on my satellite to get bit running in and out.
  
 She's really bonded with my husband, and he was gone all day.  We're going through a phase right now to where she does not want me sitting on the couch with him - we were on opposite ends about an hour ago and she completely ran over and attacked me.  (I had to get my tetanus shot updated day two of Sucre!

)
  
 When this happened, we scolded her - she seems to understand NO, but was really hard to calm down (I wish I knew exactly what she was saying!) We put her back in the cage and she screamed for an hour.  Now she is behaving totally normal.  
  
 We'd had several what I would call good days in a row, and now I feel like we've taken several steps backward.
