Dogs...My dog ran on freshly treated grass and inhale the fumes is this safe for my dog
Outside United States
This is a very interesting question. My answer is probably safe. I know probably safe is not a good answer.
I have talked to people and done some research and almost all sources indicate if the dog does not have a weakened system there is likely to be no problem.
Here are two sites you might find helpful
both sites are researched based.
You might also enjoy doing some research on your own of what non-research sources are saying. Do a Google search of "Dangers of Lawn Treatment" and you will see there is a wide variety of opinions.
While this is fun reading,I like to stick with the research-based opinions.
If I was in your situation I would document the time of exposure and the chemicals used if you know them and just watch my dog.
Please post if you have additional questions.
Wishing you the best,
