Hi everyone. My puppy keeps taking the toilet brush for a play when nobody is watching. I try to catch him in the act, but he's very good in knowing when I don't look (eg busy making dinner, dressing kids). He obviously does know that it's not right, but does it anyway. So far I gave him a stern look and said "No" putting the brush back where it belongs. This worked so far with a lot of things, but I always caught him "red-handed". Any suggestions what would be the next step to ensure he's not taking it when I am busy?
