I adopted Klöe from the pound five months ago, along with a companion dog Chochang. Klöe is a beautiful loving dog who has markings like snoopy. The pound told me she was a rotwiller mix- from her bark I could tell she had some pit in her, she howls in a high pitch tone Her demeanor is calm but can be hyper during play or when she first sees you. She minds very well and is extremely intelligent... Thankfully she comes when called and is very obedient. She is lazy and sleeps often and quite soundly. She is also nonchalant when it comes to the chickens in fact the chicken eat out her bowl and she never bothers them- she just blinks her eyes at them and goes back to sleep. Chochang on the other hand was a Shepard Mix- looked Australian with one distinctive blue eye and one brown eye. She was a beautiful chocolate brown with a beige Shepard markings. She never came when called, especially if her nose caught scent of something. I could tell from day one she possessed a strong prey drive- she pinned one of my full grown barred rock hens down and began pulling out her feathers; poor chicken was hollering for her dear life! Chochang was only about 12 weeks old when she did this! The chicken was ok, only a little startled. I thought I would take Chochang with me to gather eggs- when I got to the hen house my rooster suddenly attacked her followed by my hens- if I hadn't immediately picked her up, they would have pecked her eyes out- the hens were aiming as if guided by instinct for the eyes! It makes sense for survival to blind the predator as I was mesmerized by their team work! Chochang needless to say feared for HER dear life! I live on the east side of the Big Island and often have jungle fowl (wild chickens) that join my flock. I had both dogs on runners and kept them tide up when I was not at home and had my chickens locked away as well. One day when I came home from work chochang had killed a jungle fowl bird while she was tied up! The birds are next to impossible to catch because they are lightening fast and are fliers! Latter I observed how she caught the bird; she would crouch down behind some grass and wait for a chicken to eat some of her food. When the chicken least expect it she would pounce on them with the skill of a cat! It seldom worked as the wild chickens are quite fast and not easily taken. What an intelligent hunter use your boring dry dog food as bait, and maybe get a fresh chicken dinner! I always heard the myth that once the taste the blood they will always be killers. I considered giving her up because I was afraid she would get one of my silkies or perhaps a layer. I kept her, she was so beautiful and I would continue training both her and Klöe! Was this the right decision? What would you have done? Is it really a myth once they taste the blood they will always be killers?
