Can salt be used to kill weeds, blackberry bushes, and grass in places you don't want it? (We have 6 dogs and prefer not to use chemicals/poisons from the store, to avoid any contamination to my babies).

My Dad used to pour boiling water over weeds and it killed them every time.
I have used straight white vinegar with good success.
