I'm so sorry to hear you have having problems. I personally would never give up Sango for the world. I would sooner let my man go than my puppy. I think you've gotten some great advice here from the others. I also agree that crate training would be an excellent idea.
I'm not sure if you confine her in an area when she is unsupervised, but I think that will definetly help until she gets over the chewing everything stage. Maybe getting an X-pen to keep her in an area, free of personal things she can get into and chew on and give her some chew toys. This way it will protect you all. My major concern is if she's chewing on cell phone charger cords there's a chance that she could get electrocuted.
And that would be devastating.
Another suggestion is perhaps you can try to get Pixie to interact with him more. So she won't be as protective of you and dislike him so much. Maybe poor Pixie hasn't gotten a chance to really get to know him anf trust him. Although, I'm not sure if your boyfriend would go for that, but if he's willing to do so you guys should give that a shot. Have him play with her and give her some treats.
I really do hope everything works out for you girlie. Do keep us posted. And as the other have said before, if worse comes to worse get rid of the BF, there are plenty more out there that would love you & every aspect of your life. Especially you furbaby. They don't say "
Love me, love my dog." for nothin'
