Where Im from, some believe that cutting the dog's ears and making it eat it makes the dog aggressive or has some effect on its brain.. Im just not sure of this info, would some expert in this matter help ?
Why in the world would you want to cut your dogs ears off then force it to eat them? Way to torture your dog! Please dont do this, why would you want an aggressive dog? Also I dont think it has anything to do with making him aggressive although it could make him fear aggressive because you just caused it sever pain!
