22lr will crack dog skulls reliably even at 100yrds as long as you hit em between the eye & the ear, hart and lung shots (both lungs)also work anything else and chances of finding em are poor at best.Bonded bullets for coyote sounds expensive to me. I'v shot em with 30cal fmj and they go down as long as you dont shoot em in the tail.

head shots r not a problem
