Question: 6×6 inch hole under bushes at slab foundation in rural DFW area. Re-dug next day after filling. Claw marks visible. Moist clay soil. Horses/goats across street; woods nearby. What is it? How to stop?

Answer: Likely Groundhog (Woodchuck) or Armadillo

Quick ID Clues

Armadillo: Leaves tail drag mark; digs lawn for grubs
Groundhog: No tail streak; herbivore; digs burrows
