I just got new neighbors who have four dogs. I rarely sit in the backyard, but I used Roundup to eliminate weeds. Now, I'm switching to a mixture of vinegar, dish soap, and Epsom salt, and it's working well.

Not sure it's a good idea to use glyphosate considering the lawsuits monsanto has had over it.

The quality of RoundUp has really gone downhill lately. Guess they want to push their more expensive extra strength version..or whatever they call it.

What type of vinegar do you use? Cleaning vinegar or white vinegar, etc.? Or does it not matter ? and what percentage of vinegar? I see 5%, 30%, etc.

It's been around since the 50's and found to be safe by the EPA, WHO, etc. Legal payouts are usually the result of sympathetic juries (like coffee being too hot at McDonalds).

This has diquat in it which according to this article is worse than glysophate.

It's the main ingredient for killing weeds.
