It should be noted that the worst thing that can happen to a breed is become popular. Then you get these backyard breeders who really are criminally stupid and just into it for $$. They start inbreeding and just destroy a good breed. I saw this happen with Irish Setters in the 70’s and especially German Shepard. One of my favorite dogs we had when I was in high school was our Setter. He was totally nuts until he was 5yrs but was schizophrenic though because my brother had trained him to be show dog. So on the leash he was incredible, off the leash a hyper nutbar.
My current best boy is now a 3yrld Portuguese Water Dog and I think he’s my favorite. He is by far the most dog polite I’ve ever had. He seemed to come this way as when we got him at 12wks he wouldn’t run up on another dog. He always just sits and waits for them to approach him and does what I call the Stevie Wonder thing with his head trying to not look the other dog in the eyes. Completely non aggressive and just loves nice dogs and people. But there has been two dogs that attack him on sight. A full size poodle and a golden retriever. Both young, both male. The poodle is owned by a Karen and the golden is owned by a nice guy who is just bewildered and keeps his guy in control. Karen is just passive aggressive so Gus just gets on the other side from them and I stare the poodle down and he stays away now. The YouTube animal trainer Beckman has mentioned he’s had several golden’s that were crazy aggressive. Another victim of popular dog destruction.
