My yard is being overrun with those cutesy chipmunks. Any dog-friendly

I've tried cut-up hot peppers down the hole, but without much success. On
one hole I tried flooding them out with the garden hose but that didn't work
either.

What are they eating? If they're really proliferating there must be a
good food source around; if you can cut that off you're halfway there.
