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.

Ex Output:
Negative

I am so glad I ordered this; it is the best dulce de leche I have been able to find. I had read about this somewhere and am now convinced that many people are not familiar with this product. If you like anything caramel, you'll love this!

Ex Output:
Positive

What a great way to help with dieting and keeping on track.  These are very tasty and crunchy - great with sandwiches or salad or even by themselves.
