Need a moral weed slaughterer? Need to get rid of a few weed, I want something...

Need to get rid of a few weed, I want something to kill the weed notmy pets. Any suggestions?
Answers:    Roundup is a good contact herbicide. If it is green and growing it will massacre it. As with adjectives herbicides keep children and pets bad the treated areas until it dries.
Some chemicals are good weed murderer but it might be dangerous. I've read an article that vinegar can be used especially a concentrated one. It is sprayed on the grass but be sure its not blowy it might kill needed plants
