Pooka is 1 year, 4 months and has started barking in a bad way. She has also become more territorial and liable to pick fights with the anti-social husky that lives with us [discussed here].

Barking:
we have had to close all our blinds because if not, she just stares outside and waits for any broach on her territory and barks like mad. The more you yell, the more she barks. She won't respond to the "quiet" command at all any more. The only thing that works to lessen(not stop) the barking is to tell her she is a good girl (in a sweet happy voice) and that she is "all done" in a calm way. She still barks, but it does not escalate, and slowly becomes growling with little barks after a minute, and then stop. Picking her up also helps. Any little noise can (not will) set her off into a barking frenzy. Just setting down a drink, if it makes a "knocking" noise.
For a while we did spray bottle training, and we have now found the spray bottle and will probably start this again.

Aggression:
Pooka loves to chase squirrels, but now, anything in the backyard is a threat and MUST be dealt with, which means a lot of staring out the back window, perking up, running to the backdoor, whining and jumping around at the door ringing the cowbell. Most of the time we let her out, but only most ;). She now spends most of her time outside, sniffing around the back fence and/or barking at the back fence. (it is chainlink and maybe only 3 feet tall).

Inside the house, her and Aurora (the husky) have come close to fighting at least twice in the past 2 weeks. Once I was holding Pooka in my arms on the couch and she had dropped her rawhide, Aurora walked over and bent down to sniff it (she really isn't too interested in chews) and as Aurora approached, I felt Pooka stiffen, lightly growl, and right when I though "oh, maybe I should show my authority to emphasize I'm in control" Pooka starts barking like crazy and Aurora bares her teeth and starts coming at Pooka, but I yell at Aurora (who moves back) and hold Pooka back (she is desperately trying to get at Aurora). Today, just my husband was home working at his desk. I didn't get the details but he said Pooka was under his feet and Aurora came nearby and so Pooka started growling and almost started a fight again, even though there were no toys or chews anywhere.

Both these situations have Us involved. So she might be jealous of Aurora? or just protective of us? Ever since I had the talk with the housemate about his dog, I have actually spent more time nurturing Aurora. Once when I was brushing Aurora, Pooka came in and just got real close and stared at me super sad with her ears down, "But mommy, the furminator was our special thing!"

I think the two behavior changes are related and can be fixed. I am sure there are forum posts on this. If anybody knows some of the posts on this topic and can easily find the links, please share!
