The sweet potatoes are my dog!s favorite treat.They smell delicious and she loves chewing them. I always order the full slices because she is a standard Golden Doodle weighing 70 lbs. The slices are usually large. This last batch was very disappointing. The slices were much smaller than usual. I’m concerned about the quality control and hope it doesn’t happen again.
