Can’t answer any questions about bloodhound ears. However, I knew that Frankie was channeling Princess Leia immediately. Chewbacca? What was your DH seeing?
Earlier in life I had two Akitas. They also loved to dig, particularly if it involved their Houdini impersonations (disappearing from the back yard). With two of them working together, it was amazing how quickly they dug. They also had magical powers for making the dirt disappear so I could not refill the holes. I ended up building concrete block walls buried a foot in the ground and two feet tall to keep them in.
There is nothing funnier than two dogs working in tandem on a hole project. Wish I could have seen that. Our last dog had a buddy hole digger, the two of them together were pure comic genius. We’d never concrete walls competed here… working on the next book! Again, thanks for the push, Maggie!!!
