Well, none of us would know how to cope with a "perfect" dog, so it's interesting Dexter has developed a "quirk". Wonder what he's interested in on that carpet? Does his daddy go out that door when he leaves? Maybe he's just wanting to go with???? It sounds to me like Dexter is a very lucky dog and his daddy is just as lucky. What a match made in Heaven! (Sigh) I love happy stories.
