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?
Negative

This is soup. Very thin, watery and insubstantial. Will not order again. There were not even whole lentils in this "broth."
Negative

The dogs had been eating Purina for a long, long time. I switched to Newman's Own and I noticed something only a dog owner would be conscious of...the waste. They no longer expel foul odorous waste, which Purina seemed to do to them regularly. Since they've been on Newman's, their waste is almost odorless and, well...it is easy to pick up. You can tell it's nutritious by what comes out, and if you have to pick up after your dog daily, like myself, you'll appreciate the cleaner output.

Positive
