I know that a lot of dogs feel the need to sit very close to their owners, a couple of my mum's dogs are like that they need to be touching her or tucked behind her feet when she sits in her chair. It worries me a bit because my parents are old and not as agile on their feet as they were, I don't want them to trip over the dogs or fall because the dogs get under their feet when they stand up. Any ideas on how to train the dogs to move away on command? They are reasonably well trained but they are Shih Tzus so getting them to do anything on command is often more of a hope than an expectation
