I am bummed - she killed one of the barn kittens yesterday, the really friendly one. We have been trying to keep them separate until the kitties are bigger and can fend for themselves, but one wandered into her yard - I think he climbed through the fence and followed me to the house after I milked in the evening. This dog is from a rescue (we've had her for several years now) and she was OK with cats at the rescue - but they were indoor cats. She's a blue heeler/Aussie shepherd cross. Unfortunately we can't have indoor cats due to DH's allergies. I think it would be much easier to train her with indoor cats, as she is indoors most of the time, too. She is funny - won't chase rabbits out of the garden. But she has killed a chicken and had previously killed a kitten (a stray). So I'm wondering if she can be trained or if it's better to just rehome the surviving two kitties. She had been avoiding them when I was around so I thought she might be OK - when they are in the garage she won't even go near the door. It makes it very hard to train her when she behaves if I am around. She's the sly, quick type of killer, not the over-excited type. When she killed the stray kitten a few years before, I had never seen the kitten before and didn't see it until she grabbed it and shook it - it was out near the chicken house around dark and I thought - well, it's a stray animal out near the chickens. Maybe she is being protective of the chickens. I wasn't happy about it, but made an excuse for her behavior. Back to the present, I did tie her outside last night next to the dead kitten overnight and picked it up and kind of whacked her with it a few times, didn't hurt her physically but did try to hurt her feelings and make her afraid to go anywhere near the kittens. It definitely upset her. I don't know if it will work, but I did something similar after she killed a chicken and she leaves them alone now if one happens to get out. The big training problem is how do I get her around the kittens and train her without making the kittens less afraid of the dog? The kittens are safer if they are wary of the dog and stay in their safe zones - basically most of the farm just NOT the dog yard. I thought about putting a crate in the garage at night (where the kittens stay) and make her sleep out there. Maybe she would get desensitized, I don't know. But I worry about the kittens thinking the dog is their friend. All advice is welcome.
