Thought these were healthy treats, but found out that they are Made in China. Noted on back of bag. Concerned that it may fall into China made Jerky treats suspected to cause kidney problems in pets.

I have a recurring shipment of this product each month. Every month when the boxes arrive they are barely in one piece and VERY mangled. Last month one of the cases of water had to be repackaged before it arrived and it was a day late. I suggest using a more sturdy box for shipping. The water product is fine ... it's just the shipping packaging I have a problem with.

In my opinion, this is the best food for dogs. My boyfriend is an avid researcher, and he concluded this is the bet food for dogs on all accounts - taste (the dogs love it), health-wise (it has healthy fats, and the first and main ingredient is meat as opposed to ingredients such as corn) and digestion-wise (the dogs get diarrhea when they eat human food or any other dog food). We have two dogs we adopted from a shelter, and while at first, one of our dogs would not eat the food (he had worms though, so who knows what junk he was eating before), he soon began to understand that is what we were going to feed him and very soon, he came to love it. Now they jump when it's dinner time! Our dogs are happy, very healthy, have shiny coats, and a large part of this is due to this fantastic dog food. We get it on Subscribe and Save and we usually go through 1 bag p/ month - for reference, we have one 15lb Bichon and one Alaskan husky.
