Q.Is This Plant Over’s Goosefoot?
I have been trying to get rid of this stuff out of my horses paddocks for years because didn’t know if it is poisonous to horses and dogs. Found an app that suggested it is Over’s Goosefoot. If so, it sounds like it’s not harmful, but please confirm. Thanks, Di Willard diwillard@yahoo.com

It does appear to be a goosefoot, but it would be hard to say which species. It is safe.
