My cats sneeze around me and have running eyes but it could be dust causing it for all i know.
My moms (and my mom lol) dog starts to sneeze everytime I am visiting them.
You were not ignored, I have just been really busy at work especially the last few days. I will have some time this weekend. Have a great day.
after intensifying patm, the dogs became aggressive and some sneezed violently for several minutes.
Yes, it does happen to animals as it should but it will depend on the concentration level and the fact that most gases compounds that are toxic to humans are also toxic to animals. Some humans and animals can tolerate toxins more than others. What doesn't add up is how our own bodies have been able to counter the toxicity of this gases compound. Hopefully in the future someone can identify the compound using Gas chromatography–mass spectrometry (GC-MS). Only then can we begin to understand why it behaves as it does.
