This is an obvious response, but I thought I'd throw my two cents in:
An adult can make their own decisions when choosing how they wish to proceed…. However, I am so grateful that my breeder had done all the health testing...because when something like sudden, unexplained incontinence pops up, or you think you see a cloud in their eye....that health testing automatically rules out anything that might be "scary". It gave me huge piece of mind at times....when I just being a little neurotic. I can go online, to this day and physically see [even after I had already seen the OFFA health tests before getting him] the results from the parents, yes…it would be impossible for this dog to have PPM, Fanconi, etc.
Everyone deserves a second chance though....if they're willing to change.
