I don't know about adults. Susie's only almost 9 mos old. She's very sedate for a puppy, but I'm not sure what she'll be like as she gets older. I had a friend with a Yorkie that was still VERY bouncy at about 3-4 yrs. June Bug could jump from the floor to the top of the back of the camel back couch like it was nothing. And she was very small. |
