Question: Got this item on a one-day-only sale on Amazon. Love having the single-serving portion as I am following WW plan. Only 3 points plus per serving. Tasty and on the same line as the Special K crackers. The variety is nice to have and the box will last for awhile. Cheddar and BBQ are my favorites. Try them...

Answer: Positive

Question: My dog was on Canidae for almost 2 years and she loved it. She was healthy with a full, shiny coat and plenty of energy. Then suddenly around December she started vomiting and having loose yellow stools, and became very lethargic. We took her to 2 vets and after several hundred dollars in tests they couldn't find anything wrong with her. I did some research and found that there were numerous people having the exact same problems I was! It turns out, they recently changed their formula, changed manufacturers, and decreased the amount of food in their package. Do some research, it's not the same high-quality food it used to be!

Answer:
Negative
