I have two Akitas, a male and female. I also have a chihuahua leaving with my family. Obviously, the chihuahua thinks he is a tiger and barks at the male akita. Gets crazy when the male Akita is near. The female akita likes him. A couple of months ago the male Akita wouldnt take it anymore, and fought back. He bit the chihuahua but just let the chihuahua scared. The second time, the bite was stronger and he left the chihuahua with mobility problems and had to go to rehab to walk again. The third time they were alone, he was just smelling the chihuahua but did nothing. Finally, the other day, the two dos found each other and the akita killed him. I took the chihuahua to the vet, and the vet told me that he did not know exactly how the chihuahua died. He had blood and few bite marks. The usual in a fight. Other than that, the dog did not look that hurt. Maybe he had a heart attack of choked. In all the fights the chihuahua was confrontational and the big dog responded. By they way, someone irresponsible in my family was responsible for all these fights. That person did not take the proper safety precautions that we all took in the house. Thanks to that person, my chihuahua is dead.
