Rosemary is used to prevent the fat in the treats from going south as quickly hence it’s use in MANY foods and kibbles. That said, supposedly large amounts of it act as a neurotoxin. Example link: http://www.thedogpress.com/DOGFOOD/Rosemary-Neurotoxin-10032_Liquorman.asp
Small amounts don’t seem to be a great issue but if you’re already feeding them a food with Rosemary it may be upping the dosage to the point of bothering their stomach. Rosemary is a very strong and piney herb after all. If your dog is suffering ill effects I would definitely discontinue use. I’d wager it’s likely the rosemary or the green tea extract (used in several of them) if you’re having issues.
Contrary to some of the sky is falling posts I’ve read, Full Moon Freeze Dried Treats are produced with chicken in the USA provided by Perdue (Perdue also publically confirms this if asked) and all the ingredients, as mentioned above, are sourced in the USA. I didn’t get mine from Wal-Mart but I’ve seen them there since I bought my prior bag. We’ve never had issue with ours but when we got her she was on garbage food (Purina) so I’d bet her constitution is a little stronger then some sheltered pups. 🙂
