Input: Consider 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.

Output: Negative


Input: Consider Input: I really enjoy this coffee - I have used a variety of the K-cups and this is one of the best.

Output: Positive


Input: Consider Input: If you want to treat your tastebuds to the ultimate delight, try dulce de leche and this brand is the best! As a native of Argentina, I grew up with this stuff and no imitation comes close. Serve it inside crepes slightly warm folded and with powder sugar, with flan or ice cream and remember a little goes a long way. Very sweet!


Output: Positive
