The Last Dog On Earth

I just finished reading the book The Last Dog On Earth. It is 233 pages long. The author is Daniel Ehrenhaft. I enjoyed this book because it was full of action. It also showed how an ugly mutt/shelter dog ,can change someones life and the world. Here is a little bit about the book.

Logan Moore is always getting made fun of and no one really likes him. His step dad, Robert, is mean to him. One day Logan tried one of his inventions at the Wallace's house, a rich family on the block, and it broke many of their things. Mr. Wallace and Robert were mad at him. Robert said that taking on the responsibility of a dog would be his punishment.
Robert wanted purebred Chocolate Lab like the Wallace's but Logan didn't. He wanted to save a life at the shelter. Without discussing it with Robert, Logan's mom took him to the shelter to pick out a dog. He was looking at the dogs and there was an ugly, crazy dog. She couldn't find a home because she didn't like anyone, until Logan. He named her Jack because Robert wanted a boy dog and he wanted it to be named Jack. She wasn't a boy,but her name stayed the same. Logan borrowed a lot of books from the library on how to train dogs. He trained her well.All though she ruined all of Robert's stuff and urinated in his bathroom. Robert didn't like Jack at all. He threw a big fit about her.
There was a terrible disease going around the town. It was called POS otherwise known as Phsycotic Outburst Syndrome. Every dog was catching this disease. When they would become infected they would just lay there until disturbed. Then they would stumble and would begin to foam at the mouth. After that,blood would start to drip out of their mouths because they were bloodthirsty. Then they would attack. What was worse humans could contract this disease too. If a human was bit they would have to go straight to the hospital. All the people could do was shoot the dogs. They even had lessons on how to do it properly.
Logan and Jack were at the store and the store manager made his diseased dog attack them. Logan exploded a spray in the microwave to stop the dog. The manager called Robert and he was furious. Logan was sent to Boot Camp and had to leave Jack behind. The people at Boot Camp were mean and were getting him into trouble. They were called maggots. Logan ran away as soon as he could. While Logan was gone,Jack was kept in the basement . She was starving .She dug out of the basement and ran 40 miles to see Logan. Jack was attacked by two dogs. Both dogs were infected with POS. She was seriously injured, but didn't catch POS. Logan's real Dad,Dr. Westerly, found them and took them to his place. He was a scientist and tested Jack for POS and found out she was immune. She was the only dog that was immune and were able to make a cure from her. Jack was almost shot by Rudolph Stagg, a diseased human,but Logan dived in front of the gun and was shot. He went to the hospital to recover. A few days later Rudolph Stagg died from POS. They couldn't heal Jack's wounds because she was so injured. When Logan recovered they had to put Jack down.
In the story, Jack was a hero to all of the people and dogs. Logan was sad to see Jack go. He said he would never forget her and for the first time in along time he was able to cry. Jack was only one year old when she died. They made a cure and everyone was healed.
