I had a veterinarian friend tell me that young, crawling children are seen as prey by dogs, at least until they start to walk. We have always had to watch our McNab border collie around our grandson as he would grumble at him, esp. if he got too close to his face. We had a velcro, 2 strap muzzle we put on him when he'd been esp. grumpy and he was very ashamed when he wore it. He has not had to wear it in many years. He LISTENS very well, plus our grandson is now four and understands more about how to be careful around ANY dog and they get on well now.

I get more concerned about the "pack" at my daughter's house, 3 female boxers under the age of 2 and a very sweet OLD pit bull female known as Nanny Dizzy. For the most part they do well, but a couple of times the pack mentality as kicked in and the two alpha females asserted themselves. Steps have been taken to prevent it every happening again. They all have crates, they get extra exercise on a treadmill of all things (!) and eat in separate areas, plus my daughter and her partner are very vigilant.

I agree with SRS and Dan and others. It is not right to generalise about any breed; the people who have them are responsible for how they act/react.
