My 6 month old American Bulldog is really being naughty! When she is left alone for even a minute she is chewing everything up, it used to be when she was just left in the kitchen when I was at work and she was chewing the walls, cupboards, absolutely anything in site it takes me an hour to clean it up! I have been and daughter advice and she has a kong, fobler, new toys and she has a half an hour run in the morning including doing training. But now I literally went to the toilet this morning come downstairs and everything in site was ripped apart, the bin, a monopoly board, childs toys. She had the run of the kitchen to the garden and this was literally 10 minutes after her morning run. My house mate is now saying if this carries on she needs to leave. Please help me as she is golden when I am in the same room!
