Example Input: My golden retriever is one of the most picky dogs I've ever met. After experimenting with various types of food, I have found she loves natural balance. What I really like about natural balance is the fact that it has multiple flavors in dry and wet varieties. I mix her dry food with a little wet food and my golden loves it. Furthermore, I do like mixing up the flavors each time as I think the same meal day over day might get a little boring, so I figured why not. I tend to stay away from the fish type though as it smells... Additionally, I started purchasing off Amazon because Petco didn't have the wet food box and only had a couple of cans. I came home and to my surprise realized that I could save $20 each time I bought dog food if I just buy it off Amazon. All in all, I definitely recommend and give my stamp of approval to natural balance dog food. While I have never eaten it, my dog seems to love it.

Example Input: I have been giving my dog this treat for a long time,I found it here on Amazon and it is much cheaper! Now I learned that ALL chicken treats for dogs (and also cats I believe) that are MADE IN CHINA are being investigated by the FDA because some dogs have died after consuming them. These treats and all Dogswell treats are made in China,I researched all over the web about this matter and bottom line is: why take the risk? A few sites say it is OK, most say to be cautious and others say don't buy.I threw out all the ones I bought and got new ones made in USA.I wish Amazon gave us the choice of "made in USA", for now I recommend everyone that has a pet to read the labels of the treats and food. Sorry this product, I don't recommend.

Example Input: It is a good concept to carbonate juice. The kids loved it and called it "soda". It has a nice flavor but it is difficult to taste the individual fruit juices though.
