Is Roundup safe for dogs? What both labels say

Short answer: keep dogs away while you spray and until the spray has dried. That is what both the old glyphosate Roundup label and the newer formula label say. Which one you have matters for the ingredients, not for the re-entry rule.

First, which Roundup do you have?

Bayer says it is no longer producing glyphosate-based Roundup for the US residential lawn and garden market, lists fluazifop-p-butyl, triclopyr, diquat, and imazapic as the active ingredients in its current Roundup Lawn & Garden products, and says some glyphosate stock may remain on shelves. Look at the active ingredients on your bottle.

Roundup is sold in other formulas too, with different labels. Always match the Reg. No. on your bottle.

What this means in practice

Dogs vs cats

Neither label separates dogs from cats. The dried-spray rule applies to all pets.

Kids

Both labels say keep out of reach of children, and the same dried-spray rule applies to people. NPIC says EPA found children are not more sensitive to glyphosate than adults.

Spray vs granules

Both versions here are liquids. If you use a granular weed product instead, the re-entry rules are different. See weed and feed.

Questions people ask

How long after spraying Roundup can my dog go outside?

Both Roundup labels we checked say people and pets can come back once the spray has dried. There is no fixed number of minutes on either label. See our weed killer drying guide for what affects drying time.

Does Roundup still contain glyphosate?

Bayer says it is no longer producing glyphosate-based Roundup products for the US residential lawn and garden market, and that some glyphosate stock may remain on store shelves. Check the active ingredients on your bottle.

My dog ate grass after I sprayed. What now?

Call your vet or a pet poison line with the bottle. NPIC says pets exposed to glyphosate products may drool, vomit, have diarrhea, lose appetite, or seem sleepy.
