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: We just changed to Gerber Good Start Gentle due to sugar in this product.  This did seem to work better than a couple other formula but I decided to try something else when I read about sugar.  We just changed over to Gerber Good Start Gentle and it does (so far) seem to be working better.  He is still gassy but he has less pain and doesnt seem in nearly as much discomfort when eating (he is a little colic but still loves to eat).  I do this this is a good product and I'm sure the sugar is safe, I just would rather not give extra sugar at this age (8 weeks).  Good luck!!

Input: Consider Input: I fed this to my Golden Retriever and he hated it.  He wouldn't eat it, and when he did, it gave him terrible diarrhea.  We will not be buying this again.  It's also super expensive.
