We had a dog in our yard, killed one of our chooks. I skinned the chook (easier than plucking it, it was a bantam) and went ahead to cook the dead bird anyway, but I offered (insisted tey take) the feathers, skin, feet etc and asked them to hang it round the dog's neck. I don't know whether they did or not, but it meant THEY had to get rid of it all, and having to do so was a reminder to them of what theirdarling doggie had done, their doggie that wouldn't hurt a fly and NEVER got out, oh noe... even though they had to collect it form my yard.
We never had a second problem with that dog. And their neighbours had told me that the dog had been repeatedly getting out, through the same gap in te fence. That gap got fixed, darned quick, after the chook incident.
The only other dog problem we've had (other than a chook of ours flying over the fence into the waiting jaws of the neighbour's dog - who could blame that dog?) was a Border Collie that got in and insisted that all the chooks stand under one particular tree. The chooks looked very puzzled, that dog was very determined... but didn't touch any of the birds. I got home and the dog looked very pleased with itself, looked at me as if to say, "Come on, tell me I'm a good dog..."
Some dogs just do not belong in the suburbs, they are born to be working dogs, and should never be allowed to remain idle.
