Hi,
I agree about the crate training I think it is a much better option that a bark collar. I have a 9 year old Golden Retriever who barks excessivly when we get near water because she wants to go swimming. I talked to our trainer about the barking and the idea of a bark collar, she said that sometimes the collars work but most dogs figure out that after a certain amout of barking the yucky stuff goes away and then they can continue to bark.
Crate training is also going to protect her from doing any more damage to your stuff.
It will take time but in the long run will be worth it. Good luck,
Gina
