The seven-year-old bearded collie belongs to the National Canine Defence League's education officer, Jenny Smith, and is in south London for an hour's session with Downderry primary school's nursery class. Elegant of stature and languid of nature, Mutley is here to help the 50 three and four-years-olds get to grips with being safe around dogs and with responsible canine ownership.
"Children must know how to behave properly," says Jenny. "We don't want them hurt, and we don't want dogs to get a bad name." There's also a hint of the Jesuit dictum: get them young and they're yours for life. Or, in the society's words: the dog owners of the future will be knowledgeable and responsible.
Safety is one of the main concerns. "Children have to learn that dogs are not small human beings," says Jenny. "They don't think like us and they don't communicate like us. We can easily misinterpret what they're telling us. " This is where Mutley comes in. He's an adept demonstrator of happy, excited, bored; angry he finds a bit more difficult.
Jenny, a former primary teacher, begins with one of the league's main messages: "Toys Aren't Us - a dog is for life not just for Christmas". Try explaining that to a nursery class. But they take the basics in, with the help of their constantly reapplied thinking caps.
"What do you do with your toys when you're bored with them, when you no longer want to play with them?" she asks. "Put them away", "put them back", come the answers. "When Mutley and I finish playing a game, can I put him back?" "Noooo." They're learning.
Jenny explains that puppies grow into dogs which demand daily care, regardless of how you're feeling. "Imagine it's cold, you've got a cold, and it's dark. Do you still have to take your dog for a walk?" The children think you might skip it that day. Wrong.
She moves on to how dogs talk. What? Well, if you're going to be safe, you need to know what dogs are thinking; to learn the difference, for instance, between excitement and aggression. Mutley obligingly wags his tail; he's happy, but a slowly wagging tail can mean danger. On cue, Mutley jumps up, grizzling softly. But he's excited, not angry. If he were cross, he'd move slowly and stiffly.
"What do you do if a dog runs towards you?" asks Jenny. "Don't run, stand still and don't stare," comes back a falteringly remembered mantra. "And, whenever you see a dog, never say hello unless he's with his owner. Then you have to ask, 'Can I stroke him, and is he safe?'" For older classes, she will often show a picture of a dog in a rescue centre, which leads on to discussions about why such places exist, impulse-buying, and puppy farming. She's even been known to pick dog hairs off her jumper. This is the stuff of dog ownership.
Jenny is the league's first, and at present only, education officer but is backed up by seven external relations officers and volunteers from centres as far apart as Darlington and Shoreham, near Brighton.
As we leave Downderry to give Mutley a rest before the afternoon's session, an older pupil flattens himself against the corridor wall as we pass. "Does he bite?" More work for Jenny.
