There's an old saying that you get out of a dog, what you put into a dog.
Certainly true in both senses!
My all time favorite was a pure bred German Shepard, father pure black straight from Germany, mother a large American line shepards, outweighing the father by 30 lbs. Their son Strider was bought by me at 6 weeks, for home protection, shortly after my first child's birth. Took him through general obedience classes, hand signal commands, the whole nine yards, and what a guard dog, great with kids n seniors, but a nose for trouble makers with ill intent.
Hated staying home and doing what I bought him for!
But loved going to work with me n guardin my truck!
125 lbs, just as big as mom, and nowhere near as vicious as his pure black father, an 85 hellion, and natnl shutzin champ or something. Strider died young though, like a lotta good things do, of pancreatic cancer, probably from breathin too much carbon monoxide riding in the back of my worktruck!
