Tank is 6 months old and very food aggressive to other dogs. I keep my two dogs apart when they eat but Tank will attack the gate if he thinks the other dog is eating (other dog is behind wall so Tank can not even see him). We also go to puppy class and he will attack the other dogs for stray food on the floor. Is there any thing I can do to help him get over this? His breeder fed them all from the same bowl when they were young and I am guess that is what started the behavior. Any help would be great. Thanks.
