Dave, ITA that it's one of a doggie's best traits. Jenny may be little, but there's nothing out there like the sound of a Doxie barking...scares the heck out of anyone coming near the house unannounced. Of course she's pretty well behaved generally, and all I have to do is say, "Jenny...they're not stealing our garbage (stealing our mail)...." and she's content to continue her disapproval by low growls. Which is hilarious in a little pup!
Would Gaius actually attack someone entering the house unannounced?
