I’m old school, dogs belong outside, not inside.
I foster and train dogs as a hobby and I can always tell the ones that were "outside dogs" within the first few moments I get them. I'd hazard a guess that the majority of shelter dogs are "outside dogs"...really percolates the ol' pistachios doesn't it?
Most breeds are not "outside dogs" livestock guardians and more 'primitive' less developed breeds are though. The majority need to be physically near their people at most times (we made them this way genetically) or they get neurotic and a bit feral. Some breeds this applies especially so with like shepherds, rotties, dobies etc.
The single biggest cause of behavioral problems with otherwise well taken care of ('trained' and not abused/neglected etc.) dogs is lack of socialization. You know that famous 'protective' instinct some breeds have? It is fear response NOT bravery. Scared dogs are dangerous dogs. Unsocialized dogs do not know how to filter actual threats so they think anything outside of their experience is a possible source of danger.
Socialization is not just having your dog around other dogs and people like at a dog park (probably the worst place you can socialize BTW) its new sights, sounds, smells, places and situations.
Smart dogs are hyper autists that if they could read and had opposable thumbs would make even the most BITOGY of BITOGERS level of tism pale in comparison.
I'm not some hippy leftoid vegan weirdo either. This stuff is known and taught by every serious trainer whether its for search and rescue, police and military or especially protection work.
Most people shouldn't have dogs
