[EX Q]: I have a bichon and I thought this would entertain him for at least 15 minutes, but it didn't. He solved it quickly, within 5 minutes and looked at me as if to say, that's all?
[EX A]: Negative

[EX Q]: I was so excited when I heard about this product. I love pork rinds. But these have a nasty chemical smell and they really don't taste good at all. Don't waste your money. I actually threw the remaining 17 packages away. They REALLY SUCK!!!!
[EX A]: Negative

[EX Q]: Our black lab devoured this thing in 10 minutes, and at $6 a pop, that's way too much money for a dog treat.  Don't bother getting this.
[EX A]:
Negative
