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!!

I bought this item when it was heavily discounted (about $12) and it got here very promptly, since I am a Prime member. Every can has small dents. The discounted batch I ordered and recieved appears to consist entirely of factory rejects. They were bought 02/2012 and have a 12/2013 best by date, so not that big of a deal. None of the cans are punctured, just small dents. The contents are currently GTG.  I'd say if you are planning on eating these within a few months to a year or so of purchase, go ahead and do it. If not, I wouldn't trust dented cans beyond their best by date, or even really too far before then.  As for the contents, same as you buy in the store. Wife and kid love them, which is why I bought it.  The price has more than doubled since I got mine. Perhaps I just got a reject buy... Be warned.

I ignored the other reviews about how these were now being made in China - I had checked the warnings and was comfortable that Dogswell hadn't been mentioned.  I've bought them many times, and my dog loves these treats!  Unfortunately, the most recent batch I got last week smelled really awful - like a mix of chemicals and rotten meat.  None of the bags I've gotten before smelled anything like this, and it was so strong that it filled my apartment with the odor.  I threw them out and would not recommend buying them.  It's not worth the risk.
