Lots of dog owners send their dogs to be trained though, but dont get trained themselves, so the dog does GREAT with the trainer. Then good with the owner, until the owner gets negligent, then the dog training short circuited for a few minutes.
You specifically cite dogs on roadsides. That isnt an untrained dog problem. That is an untrained human problem.
For me it was framing "holding a dog preemptively close when nothing happens" as a bad thing and indicator of an "untrained dog" that made me disagree with your characterization.
My dog is wonderfully trained. A wonderfully well behaved little princess everywhere except when a strange dog approaches her in public and sticks their nose in one of her soft spots.
Since she got attacked by another dog, she retaliates aggressively to dogs who were not under proper control and who were allowed to invade her space without consent.
I am proactive about the potential of unresponsive owners with "trained dogs" failing to properly control their dogs.
That doesn't reflect my dog being untrained. The reflects the number of untrained dog owners out there.
My dog was doing well until a "trained" dog, off the leash, attacked her. Wounded face, badly bruised ribs.
Then, about a year later, a "trained" dog, off the leash, ran up to her and went to sniff her, she took it as a threat, and another fight happened. No blood this time, but still.
Then about a year later... a "trained" dog, off the leash... same fucking story.
10 years later, I am more vigilant and proactive. If another "trained" dog is around (telltale because of the lackadaisical behavior of the owners), I get my dog right up to heel on the other side of my body and get ready.
At least 10 times over those 10 years, I have a dog running at my dog with an owner just standing there yelling "don't worry, they're nice!", me replying "MINE ISNT", and then them jogging leisurely over while I am hunched over trying to keep the 2 apart.
I dont care how well you think you've trained your dog, be a responsible owner. If it isn't your home (front yard NOT included) or a dog park, leash. Also, don't approach a dog you don't know. You don't know their history. Be aware of your surroundings and pick a route that keeps your dog leash distance from the other dog.
The theory that when you smoke, the nicotine binds to surfaces the smoke touches, causing cancer to anyone who comes near surfaces that nicotine has touched.
It was a "truth" run around in the 80s as we were discovering the nature of radiation, so lots of war on drug "research" papers got published functionally saying nicotine and radiation are the same thing.
I spent half my life legally smoking tobacco and illegally smoking weed.
I moved a quarter of a country away for the mental health of legally smoking tobacco and legally smoking weed.
I WILL NOT be dragged back into a life where one of my vices give me crippling fear of imprisonment.
Get off your fucking high horse. Mind your own fucking business. Stop asserting your will over others. Live your own fucking life. Let me live my fucking life.
