to much hunt?

My jagd hunts hard and wont stop hunting ive had to leave him at the property a few times with my shirt laid next to a tree. When i come back he will be there ive also learned to put a long weedeater string on his collar about 20 feet. But will never get rid of this dog he's the best dog ive had so far. Im just gonna have to get use to hunting big properties and not the 200 acres that ive been gonna have to let the hogs get comfortable in there first before i take him there. My only worry is coyotes and some a- hole stealing him or shooting him.
