'Dog pound' as in you have dogs patrolling the yard constantly? If so, you may be safe. If you don't, I strongly advise netting the pond as a precaution before you wake up one morning and every single fish is gone without a trace. The depth is actually ideal for herons- they will land right in the middle and go fishing for an easy dinner. Raccoons and other land predators wont be an issue.
