Can someone help me determine which kibble is optimal for my 8 pound English cocker spaniel puppy? The bags seem to make me think that due to him being around 25-30 pounds the medium puppy is best but then chewy's language notes something conflicting "For puppies up to 12 months between 21 & 55 pounds". So is it saying that the food is appropriate if the puppy is 21 pounds? Seems conflicting to the bag lingo.
