I have dogs who are 85 pounds. They chewed the bottle toy in less than 10 minutes; trashed it. I have not tried this with a little dog.

Ex Output:
Negative

Ex Input:
This is great cheese, a little sharp yet creamy, with slight bits of crunchy. Great with a micro brew. The Merlot and Raspberry are yummy too.

Ex Output:
Positive

I purchase most of my dog food from Amazon and, until this shipment, have been very satisfied. When I opened this shipment, all but two cans were severely dented -several cans were dented in multiple places. Even the inside cans were damaged. So this does not appear to be an issue with the case being damaged during shipment. Had to inspect each can for bulges or small openings, as I was concerned about contamination of the food. A lesser, but still frustrating, issue than risk of contamination is the difficulty I have trying to scrape all of the food out of each can (due to the depth and large number of dents in the cans). It is simply unacceptable that this case was shipped to me in such horrible condition. Looks like its time to start picking up this dog food myself at the local pet supply store. At least then I can be sure that the cans are not damaged.

Ex Output:
Negative
