Input: Consider Input: I got this drink expecting the carbonated taste combined with kiwi and berries. Well I could taste the berries but no kiwi. I did like the carbonation with real fruit juices without the added sugar but it is not low cal. I think that I liked this drink better than the tangerine drink but still is not for me. The drink is way too sweet for me to enjoy it.

Input: Consider 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.

Input: Consider Input: My male Maltese dog had been enjoying the Old Roy's Puppy Biscuits from Walmart. Then I couldn't find them. I was desperate to find a treat that would measure up. I ordered six bags of the peanut butter and crossed my fingers. They arrived, and my little guy loves them. He gets one heart-shaped biscuit at bedtime. He sleeps in a crate. When he hears me touch the bag of treats, he beats a path to his crate in high excitement. They are a BIG hit with my him. They are well worth the price. They are high quality and I can even smell peanuts in them.
