Dr. Phil, I'm very sorry but that's utter BS. Not all pound dogs -read about 90%- have bad histories, have been abused, will attack again etc etc. .............. So pls don't generalize.
I did not say "all" pound dogs could suddenly turn.... but when dealing with children I don't deal in probability. If there is a risk and its an avoidable risk, I avoid it.
And when these dogs do turn, even if its only 10%, which I can not dispute figures, it usually involves an innocent act such as a child pulling the dogs tail or a sleeping baby which has received "too much attention" from parents.
Abused dogs will always carry their experiences. Treat them well and they will surely conform, but that's not the same as reform.
Like you, if I were to get a dog I would also go to the pound and find a mongrel. But I would not recommend it to someone knowing it will be in frequent and close proximity to children.
The choice of dog should not be dictated by your well placed sympathy. Its about children first, dog distant last.
I have heard my cousin talk of these matters and he's a top UK dog breeder.
