Well it is my opinion that any feral,wild dog ,dingo cross is fair game.SHOOT ON SIGHT
Domestic dogs at large are given the oppertunity to come to me when called or whistled,however if they turn and run a texas heart shot with anything handy will do the job..

Prefered calibre ,well most times I've come across dogs that need to be shot I've been carrying either a bolt action 243 or 308...

I've only ever used dogs to hunt feral cats and my dog of choice has been the Jack Russel terrier....
