On the downside, I have found most pet store, and back
yard bred Goldens, and even many show dog bred dogs, to be defiant to obeying commands.
Quality of life issues are also not included in these studies — i.e. maybe my large -
breed Golden Retriever intact male won't succumb to bone cancer, but what if he gets out of the
yard and gets hit - by - a-car and sustains pain and injury instead?
