When I was around 7 or 8, I had a pet Doberman pinscher named Suzanna. She was friendly and loyal and was always happy to see me.
For whatever reason, my dad had her chained to her doghouse next to my grandparents place(their house was immediately next to ours). She stayed there until I let her loose and we’d go and play around the houses.
One day I went to unchain her and she was gone. I freaked out. I called and whistled and about 10 minutes later she came running up to me, waging her stump of a tail and greeted me with a smile.
I scolded her for running off. Then I petted her and showered her with, “that’s a good girl,” before I noticed the chain we used to keep her leashed was broken.
A chain(albeit rusty) leash was broken.
That’s definitely Stronger than Groonk.
Now this was a tiny-ish domesticated canine. I can only imagine what happens if your pet hyena pulls a Chief Bromden.
