She does it even when she's perfectly content, no stress from what I can tell. She doesn't ever destroy anything, it's just very irritating for me to listen to, and I am sure it's bad for her teeth. Why would she be doing this?
shes 6 and not teething

I have 5 Chihuahua puppies that are 4 weeks old... When will they get their teeth?

I have a 10 week old chihuahua puppy and he likes to chew on any little thing he can get his teeth on including things like the carpet and my feet. I have some soft rubber squeaky toys and a couple little stuffed animals but I wanted to try some sort of bone for him to chew on. Are nyla bones appropriate for puppies?
