I can feel the pull of glyphosate. I want to kill the weeds right around my house, but that's where my dog sleeps and rolls and eats the grass. Roundup is the popular weed killer and I've got a bottle in the garage. So I look up its effects on pets, and it says "manageable with precautions", particularly waiting for the fluid to dry before letting the dog on it.
I'm not very comfortable with that so looking around for other solutions I see a guy on Youtube telling me how to manage weeds with vinegar. I figure that must be safe, so I buy a bottle of the recommended concentration, but for the hell of it look up its safety for dogs before applying it. They say hell no, this is way too strong for pets and can cause burns, etc. I would need to dilute it quite a bit, making it a lot less effective.
So I ended up using glyphosate, but I'm looking for something better.
Unless you have an old Roundup bottle, you don't have glyphosate in it. From the Bayer website:
"The active ingredients found in our Roundup Lawn & Garden products in the U.S. are: fluazifop-p-butyl, triclopyr TEA salt, diquat dibromide and imazapic ammonium. These ingredients have been used safely and effectively in many different weed-control products from a variety of companies for decades."
"We have been very transparent about the new formulation of Roundup Lawn & Garden products and are no longer producing glyphosate-based Roundup products for the U.S. residential lawn and garden market. While Bayer no longer produces or sells glyphosate-based Roundup products – which are also EPA-approved – some quantities may remain on store shelves until remaining stocks are sold. "
Weeds on the lawn: just use a lawnmower each week, the grass will usually handle being cut on a weekly basis much better than any weed.
Weeds between tiles / slabs or on gravel: just pour boiling water over them. The weeds will become mushy and die within 1-2 days. Repeat every 6 weeks during summer.
Source: we bought a house with a garden full of goutweed [0], which I consider the final boss of any garden owner, and which we have in control now through regular mowing / hot water. Goutweed will just laugh at any herbicide you throw at it, and regrow from its underground rhizomes. I also doesn't seem to require sun, because I have seen plants grow to a height of 10cm completely underground. The joke in my family is that it could grow on foreign planets. As Wikipedia dryly puts it: "Once established, goutweed is difficult to eradicate."
If it's dandelions, wait a few seasons (now that you've used Roundup) and then eat them! The leaves taste like arugula (the younger the better). The heads, when they bloom, can be dried, ground, and baked into cookie recipes. If you let the heads close, pick them before they start transforming into seeds and either pop them into your mouth raw while you're doing yard work or save them, bread them, and fry them up for a nutty flavor. The roots apparently make a good caffeine-free coffee replacement but who the hell wants to replace coffee?
How about not killing the weeds? One doesn't need to live a perfectly manicured pesticide-ridden hellscape.

Doesn't the vinegar act pretty quickly? Keep the dog inside that afternoon, then hose it down in the morning.
Depending on weather and the site, a weed burner can be very effective for what people used to use glyphosate for.
For large areas, tarping can work pretty well in the summer. I accidentally cut a perfectly rectangular hole in my lawn by leaving a tarp on the ground as I was moving soil into containers. Enough sunlight was absorbed through the translucent plastic that it quickly baked the area underneath to death.
you had to choose between vinegar and glyphosate, I'd use the vinegar. your dogs aren't going to roll around in a too-strong concentration of vinegar, it has a smell and if it were actually going to cause burns (what kind of vinegar is this, something from a chemical supply house? ) animals would be immediately repelled by it (plus it evaporates quickly anyway). whereas with glyphosate, none of that applies, it's a fully synthetic chemical that stays in the atmosphere for days, would not send any cues to animals, and its effects on animals may be long term, concealed for years, and fatal.
but as someone else said above, if this is a certain area that your dog wants to be, you can always pull weeds for that area by hand, just make sure you get the entire root.
absolutely insane that you held glyphosate and vinegar in two hands and decided to opt for glyphosate. vinegar will not hurt your dogs. use vinegar, or fire, or drench the weeds in water and pull them out by hand.
You sound neurotic. Anyway just pull the weeds out with a towel and you hands, or use boiling water to kill them
As I'm sure you're aware, glyphosate is usually only appropriate as a weed killer on your property if you're looking to kill all vegetation in/around where you spray it. For example if you wanted to "nuke" your lawn by killing all the grass and starting over with new grass. It's a non-selective herbicide in this context, it kills everything.
If you've got some dandelions or thistle, and it's not out of control, the nice safe way is to pull them up by hand or, if they're between pavement cracks, pour boiling water on them.
Broadleaf weeds growing in your lawn that aren't easily hand-pulled can be killed with a selective herbicide like 2,4-d. Tough underground vine-style weeds like creeping charlie or wild violet will need a selective called triclopyr. Crabgrass is best killed by a selective called quinclorac. Yellow nutsedge requires a selective called sulfrentrazone or another called halosulfuron.
Selectively kill the weed infestations as best you can, get rid of the bad ones before they go to seed, and focus on the health of your grass -- in most parts of your lawn, healthy grass will out-compete weeds.
