Are There Dog-Friendly Dandelion Killers?

Sunday makes a weed killer called Dandelion Doom and Sunday’s products are pet friendly.

Dandelions usually thrive in densely packed, calcium-deficient soils and sparse, closely mown grass. You should conduct a soil test to determine any nutrient deficiencies. Encouraging the growth of grass should help to reduce dandelion growth.

Not a spray, but I love the Garden Weasel (Amazon). When I first moved into my house, I went through the whole yard with this thing. Yes, it took a while, but it was so satisfying to pull those suckers out by the root. That, combined with aeration and overseeding the lawn, and I now get maybe two or three dandelions each season.
