We had a blue heeler that bit a homeless man's beer bottle and shattered it. We took her to the vet and she didn't even need stitches. The guy was so drunk he just wandered off.i agree that they do make good pets, to the owner i dont think you will find a much more loyal dog. but you have to work with them, people around here dont seem to want to take time to do it. they tie them up or put them in a kennel and wonder why they get bit every time they try to feed them. they are a high energy dog that needs room to run, and they are high strung and need to be worked with. they are fast learners, if you just spend some time on them.
the issue with getting rid of them here is their tendency to bite strangers. here in Ohio if you have a "beware of the dog" sign, you are admitting you know the dog bites. any dog owner is responsible for medical bills from a bite. the way around the law is to put up "caution attack dog signs" and have your dogs inside a fence. with this, you are warning people that the dogs are trained to bite, you cross the fence at your own risk. if someone does cross the fence, they have to prove they cant read to put the liability on you.
