Oh, don't let your dad give up after just one day home!!! Dogs take a while to adjust to their new home. Tell your dad that - ask him to give you a week. I'm sure he'll calm down by then.

And as for him getting along with Beanie, do a search in google for "introducing a new dog" and you'll find lots and lots of pages about introducing a new dog to your resident dog with out trouble.

Good luck, and don't give up!
