Little strips of doggie delight.
I buy these regularly. My three dogs (1 great dane, 1 staffie and 1 westie) each get one on a morning and one on an evening at bedtime. I also give them occasionally during the day as a treat if they have been very good, and cut the strips into pieces (about five per strip) to use as training treats.
The dogs LOVE them and will do anything for one - and as they are pure dried protein, I can be assured that they won't make them fat.
I also have two cats with enjoy them too, and frequently used to find the bag shredded open and the chews chomped! I say used to, because now I transfer them into an airtight container as the little divvils were stealing so many. Thoroughly recommend these. (I'm half-tempted to try them myself . . . they smell very inviting.)
