Here's another one of my dogs' favorites. These are inexpensive, can be broken into small bits (they do not need a whole one) and are great for training. These are not very healthy and I would consider them to be "candy for dogs", so give sparingly. The last thing you want is an overweight dog. A dog also needs to "earn" treats. Coming when called, sitting, shaking, dancing; it doesn't really matter what it is, but it should never be given for "free". Dogs respond best to earned treats, which is especially true for maintaining good behavior (like listening).
Snausages also come in other shapes, like little footballs and the original little rolls.
