Example Input: This toy is not that great for my pug. He loves finding stuff in the little cups, however the yellow covers are impossible for him to get off. His mouth won't fit around them so he can't pick them up with his teeth, when he uses his nose to try to get at them the cups just fall back into place and if he uses his paws (that's when he's really frustrated) he winds up just flipping the whole thing over. I have turned the cups upside down so that he can grab at the edges and that works for him. However, it's not really a puzzle because he even figured out that if the cup is sticking up, something is in there. I even have a hard time getting some of the cups out because of the way it is shaped. It's not a bad toy as a starter puzzle but if your dog has done puzzles before, this one won't keep him interested. And if you have a dog with no snout, it's not really worth it.
Example Output: Negative

Example Input: I bought these for my vegan father who LOVES the curry kale chips by Rhythm Superfoods (my 22 month old daughter, husband and I also like them)!  Thought I would give him a new kale chip flavor--BBQ--as part of his Christmas gift. Although a different brand than we typically eat, they sounded good. First, I was disappointed to see these chips are not kale in its natural curly form but pressed into round, dog-snack-looking discs. Luckily I tried them before giving them. I spit it right out! Was it just me? My husband also tried one and couldn't finish even one chip.  I have a pack of 4 that cannot be returned... what a waste of food and money!
Example Output: Negative

Example Input: Might be a little spicy for some, but this stuff rocks. I use 1/2 and1/2 with V8 for a milder version , or the best is a Bloody Caesar! Half mix ,half clamato!
