Our Chihuahuas are as different as night and day temperamentally speaking.
They are AKC. Some of that variation in all "breeds".
Some dogs are not bred to be smart. But there are exceptions within those breeds.
Does a pound puppy count as a rescue dog?
If so, the big yellow dog that we got some years ago was sick.
250 dollars later after a change of vets, got him well with massive tetracycline..
Rumor had it that the county pound we got him from was not vaccinating for "kennel cough".
That's what we heard, anyway.
Unlike other dog, every story I've heard about German Shepherds being aggressive was that the aggression was directed at someone other than the owner's family.
That was my experience too. After mine showed aggressiveness toward the kid next door who was in my yard, I never trusted her around strange kids.
Otherwise, I think Shepherds are excellent family dogs. Never heard of one turning on the owner.
They can have a strong prey drive and are protective.
My experience does not mean someone else does not have a different story.

They don't smell or shed.
