TJs Expired Dog Treats (Norwood area, Bronx, NY)

Hello, I didn't realize I had so many leftover, Expired, Dehydrated Trader Joe's Chicken Breast Strips packages and unfortunately, my dog of almost 17 years passed away. I did a search and according to this website :

https://www.google.com/search?q=How+long+do+dehydrated+chicken+breast+strip...
It states they should still be good up to 12 months past the expiration date if stored properly and unopened, which they all were kept in a dry, dark place in my food pantry.

If you know otherwise then please send me valid information, ASAP!!!! I wouldn't want any pet to get sick because of me, for now, they are all available for FREE. First Come First Served!
