The back yard area, where the dogs go poop, is not landscaped and wont be for quite some time yet. It's full of weeds and hubby was going to spray Round Up on it. I was worried about it hurting the dogs so told him not to; I'd weed-eat it instead. I only got 10 minutes into it and had to stop; my arms cant handle it. Think it'd be okay to spray it? They're not out there too much; they go to the bathroom there and I put two of them out there when I leave the house. The rest of the time they're all inside. Even if hubby weed-eats, the weeds will be back in a few weeks. Opinions please? My arms are KILLING me!
