Dog with a sucking problem

October 3, 2009 -

I have a Boston Terrier that is will be 6 months old October 16th. For the past few months he has been constantly sucking in his stuffed animals. Its only certain ones too. He has 3 that he goes back and forth with. He is not biting with them. He is just like a baby when they suck on a pacifier. We thought it may be because he was still teething but even know that he is done teething he still does it. Is this something that we should be worried about and try to prevent him from doing, or is this something that is harmless that we can just let him do? Thank you for any replies.
