I bought this because I have celiac disease and was really craving some muffins.  I am not a health nut, I just can't eat gluten.  With that said, this is nasty.  It calls for very little sugar, I figure for the health nuts, so I simply added more sugar since it said to sweeten to taste.  Even with extra sugar, it leaves an extremely bitter taste in your mouth.  I would rather pass on muffins than ever taste something like this again.  On a positive note, the muffins do stay together and look like muffins and if you try the product and dislike it, you can mail in the bottom of the box and your purchase price for a refund.
Simply Nasty

I placed an order for Dogswell Happy Hips for Dogs, Beef Liver on 6/25/12.  On July 5 when my current supply was used up, I opened the new batch.  Started with one pouch and then a second pouch.  For the first time the product doesn't appear to be healthy and fresh.  Instead of being solid brown, hard and crispy, the beef liver pieces are soft, pliable and some have a whitish powdery covering on them.  I'm afraid to feed these to  my dogs or other dogs that I meet in the park.  I've been buying this product for years and this is the first time it doesn't look and feel right.  I'm going to try to get an exchange hoping that this is just a bad batch.  One thing I did notice when the package arrived and that is the long, tall plastic bag was substituted with a horizontal short bag that didn't fit the 6 pouches very well.  My guess is that another manufacturer is making this dog treat, not the original one and that's the reason for the inferior and unhealthy quality of the treats.

My baby loves Rice and Lentil and is one of her favorite things to eat.  If we are going somewhere I won't be able to warm the food she will eat this one cold.

Great
