Contains: Duck Wings Each large bag contains 8 wings totaling 2.5lbs of pre dried weight, leaving us with just under a pound of fully dried wings! aka Nature&&';;s Perfect Toothbrush (for the right size appropriate dog) For dogs around 30lbs ish and under, these do an excellent job at getting in between those hard to reach crevices with it&&';;s unique zig zag shape. For dogs much larger, they can still have them, but the whole thing would probably crumble into pieces after one big ol Chomp!! Not much dental cleaning to be had there, but still a delicious treat nonetheless! Save around 15% off when you upgrade to an 8 piece pack! Best Suited For: Small to Large Breeds Storage Instructions - No need for a freezer or fridge, this item does just fine in a cool and dry space!
