I am so glad someone brought this subject up. We got our Meeko 4 weeks ago he was 10 weeks old. He went straight to town on our female yorkie. I was mortified Then he started doing it to my daughters stuffed animals. I called the breeder up and ( with a little laugh in her voice ) she said this is quite normal and not to worry. She incourages it in her breeder dogs. "I'M NOT GOING TO USE HIM FOR STUD". She said the behavior may stop after we get him fixed.... I sure hope so. Other than that he is the sweetest little dog.
