If my dog had ringworm, would I know it?

you can get ring worms by playing in some weeds so they can't say its from your dog just keep an eye out for any thing to change but if your dog had it you and your daughter should of have one .. my nephews played out sound and every time they would play around this little bush patch they called a club house that got ring worms so we stopped them from playing there and they haven't had any problem and none of us have any animals so they can't point fingers I hope this helped you out
