One morning Mrs．Andrews made some sausage sandwiches for her husband's lunch．There was one sausage left over．Mrs．Andrews didn't like sausages herself and so she gave the last one to Henry，their little dog．Henry ate it up quickly．

During the morning the dog got ill．He wouldn't stop shaking his head and he couldn't stand up properly．Mrs．Andrews thought，"He has eaten something that didn't agree with him．Maybe that sausage was bad…"She suddenly remembered her husband's lunch and called him at the office．

"Jim，I hope you haven't eaten any of those sandwiches yet．"

"Yes，I have…"

"You have？Well．Listen，don't eat any more．I gave Henry the last sausage and now he's ill．Go to the doctor，Jim．Tell the doctor about the dog．Get some medicine at once．"

Jim came home at lunchtime and went to bed．"I have a very unpleasant hour with the doctor．"He told his wife．"The medicine made me very sick．"

The next morning Jim was fine．Henry seemed quite well again，too．At eleven o'clock the milkman came with the milk．

"Good morning，Mrs．Andrews，"the milkman said．"How is your dog this morning？I have been thinking about him…"

"Have you？Well，he seems all right now，but…"

"Yesterday morning he and I had a little accident．He jumped up at me and I dropped a bottle of milk on his head．"
