Weed control with dogs in yard -

[GeauxLSU]

So with all this rain and now the sun's finally out my back yard is ATE UP with weeds. We use a service for the front and side yards which look great but the back yard is pretty sad.

I hesitate to use chemicals because of the dogs running around back there.

So are there any pet safe chemicals that work?

Is it too late to use something like Round Up? And if I did use it - how long to keep the dogs off of it?

How about a propane torch for weed control? I bet I could get my boys to use that - as long as they didn't set everything on fire in between.

Other than hands and knees pulling weeds anyone have any suggestions?

We have the same issue. I don't put chemicals in my back yard at all. (Plus we have fruit trees). Once the soil heats up good in the summer, most of the weeds will die off. I can tolerate it until then. Then take care of the grass properly. The best defense again weeds is a healthy lawn (and the right type of grass for the conditions).
I did pickup up some all natural herbicide. Intend to test a few spots today if we get sun. Will report back....
