Last but not least, Buster, my Chihuahua, was 6 years old when I got him. I've now had him almost 3 years. He had lived in a small rundown trailer with 3 other chihuahuas. They had all been abused and had never even been outside before. I don't know where the other 3 are today. It took a while for Buster to warm up to my husband and he still isn't real sure about any other men that come to the house. But he now knows what the sun and gass feel like and he loves it! We call him our little pig because of his cute little pink pig nose.
