A shepherd had a big sheepdog who guarded his flock. Because he was a big dog, he ate a lot of food.
"Why don't you sell him and get a couple of smaller dogs instead?" advised the shepherd's friend. "You could save some money on dog food that way."
The shepherd agreed, so he sold his big dog and replaced him with two much smaller dogs.
As soon as the wolf saw the new sheepdogs, he attacked the flock, killing many of the sheep.
"Alas!" wailed the shepherd. "Just to save a little money, I have suffered a great loss!"
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 841 in the book, which is not in Perry's catalog, but it is found in La Fontaine.
