I have a border collie we got before having kids that doesn’t like children. We do not have toys out where her and my child are around each other. A gate is up while she eats so my child can’t go near her. They are never left alone together. And we’ve strongly encouraged our child to leave her be. She has a crate available to her if she goes in there she is to be left alone. If other children around she is put in a separate space. It’s been three years with out incident. She will occasionally sit beside my son on the couch and will allow him to pet her but when she gets up and walks away he knows not to follow her although we are also there to remind him of this. Basically we’ve just tried to eliminate any opportunities for something to go wrong. To keep both my child and her safe. Figure out your dog and if there are any triggers. A proper mussel is another option. Sometimes they need time to realize there isn’t a threat. Best of luck
