All dogs come in different shapes and sizes. I have a friend who has a dog, but her dog is not big like Buster. My friend's dog is small with white and brown fur, and is called Scotty. When Scotty was a puppy, my friend made a little bed for him with a bucket and some blankets, and Scotty still sleeps in that same bed. Since Buster cannot fit in a bucket, he likes to lie on a rug in my room and sleep.
I have my own bed that I sleep in. I usually do not let Buster sleep on my bed because my bed is not very big, and when Buster does lie on it, he leaves his fur all over my blankets. But I like it when Buster sleeps in my room, because he makes me feel safe.
