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.

Ex Output:
Negative

I've bought these at the local supermarket and enjoyed them although they are so salty that a few leave my tongue and roof of my mouth burning.  Keeps you from eating too many!  Occasionally I get really stale items from Amazon.com and this was one.  Unedible.  Beware of the quality of food items on this website that are on special as they can be very close to due dates or in this case, not expired but stale and unedible just the same.

Ex Output:
Negative

I always feel refreshed when I drink this coconut water. The pineapple gives it an added extra that makes it truly irresistible. It has been a firm favorite of mine now for nearly a year.

Positive
