This is my poodle/airdale, Sam.
His first owners abused him untill he was 2 years of age, then he was taken to the pound and held there for 3 weeks. I got him the day before he was to be put down.
I was told that he was tied on a very short chain outside 24/7 and when I got him he was not nutered or house broken.
As you can see, he lives a nice life now, All the chew toys he wants and walks 3 times a day. (He's a fatty too.)
