I am involved in trying to establish a conservancy in Zimbabwe and need some advice on dog breeds that will be needed.

The area has a problem with poachers coming in at night armed with spears and with dogs to poach. The anti-poaching patrols are unarmed and out numbered when they encounter the poachers at night. When the armed guards go out to intercept the poachers simply lie low in the dark and then disappear into the night.

The guys on the ground are wanting to acquire dogs to deploy with the anti poaching patrols. They are looking for tracking dogs to follow up and follow the scent of the poachers and then attack dogs to attack the poachers and/or dogs when they catch up to them with the armed response.

Please can I have some input as to what breeds are recommended for:

a.) Tracking; and
b.) Attacking.

Many thanks
