Let us all keep in mind that most of the time CCL injuries are due to luxating patellas which are considered to be genetic. Some of these examples and comparisons are misleading if you ask me.
The bottom line is that someone said that MOST owners should not have intact dogs and I could not agree more. The vast numbers of unwanted dogs in this county is beyond comprehension; and I think it is irresponsible for anyone who truly loves animals to advocate that ALL pet owners worry about altering their pets. Of course those are just my thoughts....and yes, I know people will spout their opinions just as I will spout mine.
