im a country boy and have a large yard. living in the country you find yourself fighting snakes and rats. the best way to keep the numbers down on both is cats. i noticed that if i put my pups on chains where they could see the larger dogs run the chain at the cat they would start hating them too. BAIT the hook. i run two very different lines and so my methods of training may cause for either are. carpet over tread but cat mill over everything
