I've owned a lot of breeds.
If you want a private bodyguard dog for you and your family.........doberman.
If you want a goofy AF, but killer at time........rottweiler
If you want an inside dog that alerts to trouble........schnauzer
Avoid labradors, golden retrievers, cocker spaniels, etc. When I was ten years old me and my dad went to a "puppy mill" and I thought a golden retriever was such a great dog to have and
my old man sobered me up quick. "When the nigger tries to break in your house or walk in your yard, which is better? A golden retriever to roll over and play fetch? Or a doberman that will chew
that fucking coon's leg off and eat out his eyeball?" From then on there was no question on what I would ever get.
