Is borax safe to use in the house when a dog is the house at all times?
I wouldn't just leave the stuff down. I use it to kill fleas occasionally one room at a time but keep my pets away from that room for 24 hours then clean it up well.
I read that a small amount won't do any harm to a healthy pet but I don't want them to even sniff any at all. If you are using it for roach control just put the stuff behind cabinets and fridge where they can't reach it.
Not if the dog will be poking around at cracks and crevices and baseboards:
