My parents got us a cute little beagle-esque puppy when I was about 5 or 6. It grew into some sort of half-greyhound speed demon hellbeast. Our yard wasn’t fenced, so my dad built a kennel/run enclosure for him. I remember the fences being just taller than my dad, so maybe 6 feet?
Two nights after he built it we came home to find the dog standing in the driveway.
