As a general rule, always supervise your dog when it is close to a child. Remember the dog maybe a domesticated animal, but 70% of its brain is still untamed ( uthats why dogs go by pack behaviour rules ebven when living in human environment). I do not mean to say that your dog will harm the child, but protecting your child as a mother has priority over the faith and trust for a well trained animal. A german shepard as it was originally a herding dog, ( before WW - II, where it was used to track escaped prisoners and patrol borderlines). So GSD which stioll has herding instincts might try to herd your child away from danger ( fo eg: falling froma step), but in push the child with its muzzle so hard that it can bruise the tender skin. Also suddenly if the GSD feels like moving your child away from danger, it might lightly grab it to take it away, and I dont want to tell u want might happen!!!!!!!. So pls use supervision at all times.
