Vet said that his best guess was that Calvin was some sort of beagle / birddog mix. Too tall for a regular beagle but still has the bark and digging tendencies (lunar landscape backyard, IOW).
As for your doggie gate, be creative...like me! (damned if that hound didn't chew up one of the clamps I had hooking it onto the stairs, though. Babygate in the doorway to my great room and this kept him from jumping the stairs!
Check out the innovation (and mess...thank you shoe muncher!).
