Gertie was a pill when she was tiny. We got her at not quite 6 weeks and she bit and chewed something horrible. We got her to stop that tho and she's been a good girl ever since. Ida was older than Gertie, about 12 weeks old when we brought her home and she is much more calm, no biting or chewing at all. But she's apparently never heard that dogs won't soil their sleeping area. She is 6 months old and STILL goes in her crate at least once every 7 to 10 days. She doesn't care, she just lays down and sleeps a foot from the . They both play pretty wild, so I guess I wouldn't say they're exactly laid-back. But they're still pretty young.
