I have never heard of Rosemary extract causing stomach upset in general, I think some dogs are sensitive to it, but I wouldn’t blame it for your dogs stomach problems. Personally, I try to avoid any jerky treats because there have been HUGE problems with dogs getting sick from jerky treats made in China. Even if treats say the are USA made, the company could still source ingredients from China. I wouldn’t feed the jerky treats anymore, or any treats that upset her stomach, but I don’t think Rosemary is necessarily to blame.
