Monty is 9 months old and seems to have found the devil in him!!!!He is being very stubborn and seems to do things just because he knows he will get a reaction from me!!!He would keep taking the pillows off the couch and walk past me with it in his mouth waiting for me to chase him to get it back. This went on for a while and I ended up putting the pillows away....so the next day he come strolling in with the actual seat cushion off the couch in his mouth. He is constantly taking the tea towel off the hook in the kitchen, he doesn't seem to chew it but just take it and drops it. Please, is this just another phase that I wasn't expecting? He can behave so well, but at the moment he seems to spend more time in 'time out' than ever before. Am I doing some thing wrong?
