I have purchased this product in the past through Amazon for my twins and it was good. However, the last time I ordered the 6-pack in June, the cereal was stale and smelly. I opened a few cans and they were all the same. I called Amazon customer service and they were very helpful and gave me a refund. I don't think I will purchase this item again through Amazon, although I do purchase the majority of items for my twins(including diapers) at a great price from them.

Ex Output:
Negative

This is the second "Tug-a-Jug" food puzzle I've purchased for my wire fox terrier. The first lasted about five months until she chewed through the rope. But this toy kept my dog more occupied than any other food puzzle I've tried, so I decided to purchase a second one. My plan was to put this one away as soon as my dog was done with her food so she wouldn't "play" with it and chew through the rope. So in other words, I blame my dog's destructive terrier prowess on the demise of the first toy rather than the manufacturer.  But after just one week of use for the second toy, the bottom part where the end seals onto the main container literally cracked and shattered into many pieces when I was sealing the toy.  My dog may chew through ropes but she's not that rough with toys, and I was using normal strength to twist the end piece on, so I'm pretty sure this one was a dud. But after that, I'm totally done with this company. The shards that came off in my hand were tiny and sharp enough that if just one shard had broken off without my notice and go mixed in with my dog's food, she probably would have ingested it and had internal bleeding.

Beware - This product may contain sharp pieces of husk that can get lodged in your mouth or throat . I've been buying this granola on a subscribe and save basis and love the taste . Unfortunately , on several occasions I've gotten sharp bits of husk slivers imbedded in my mouth . One particularly large piece that was shaped like an arrowhead lodged deep into the back of my tongue causing me intense discomfort and uncontrollable gagging until it was removed . I've been going through the remaining product by hand and have found them in almost every package . When they say Au Natural , they mean it .
