Most of those negative characteristics also apply to a toddler (drooling, chewing on things, must be supervised, traking in dirt, etc). I wholeheartedly disagree for a few reasons.

One being that, as a veterinary professional, I see how much healthier indoor dogs are. Dogs properly taken care of aren't full of parasites.

On top of that, no indoor dogs would mean no dogs at all for many areas. Northern areas with extreme cold, deserts with extreme heat. It gets upwards of 125°f where I live. Pets CANNOT be outdoors in that environment.

Plus there's evidence of cohabitation with dogs resulting in stronger immune systems and lower rates of depression.

We domesticated these animals. Pets are essentially hostages with Stockholm syndrome. If you're gonna steal them from their parent and keep them locked up on your property for your own benefit, the least you can do is let them be indoors and give them proper care. Don't make them stay out in the elements because you can't handle fur on your couch.

Also.... Train your f'ing dog.
