OK, cant keep quiet anymore on this one! Any dog that absolutely, no way would leave its home or property without its owner isnt neccessarily a well trained superstar, it may well have some worrysome behaviour issues (similar to a human whos too scared to leave their home).
Ive got dingoes and theyd head for the hills if the gate was left open - one of them is a fully trained cane toad detection dog - so shes hardly untrained or a bad dog. I think the person who started this needs to get their facts straight before labelling 90% of the dog owning population irresposible, incompetant or a being bad owners.
Ok, had my vent now!
