I have two demon dogs that will destory anything if they get bored.
I have had to confine them to a portable cage like pen when I am gone to prevent them from tearing apart the house. Yes this is an indoor assembly!
This is the part you will really like. we walk them for an hour every morning, an hour midday and over hour of off leash running in the evening.
I don't think you need to go this far but exercise will go far but the downside is they will get in better shape and get stronger.there are good books out there for training.
Apple bitter might work, my male chewed up a bottle of the stuff though.
