I have only stray dogs ! .. those once were once I either rescued from the streets as pups or some I rescued after accidents with vehicles !
Don't wanna boast, but the "stray" dogs that I have up-to-date have
killed yeah
KILLED two rottweilers, one German Shepard, maimed close to 12 people and put 2 "would be robbers" in the ICU !
This is in a span of 7 years
Never underestimate the power of an "animal" when it's threatened or protective... even if it's just small stray dogs !
Very low maintenance costs and from personal experience I know that they are more loyal and lovable than breed dogs. The best of all is that they carry the raw instinct of their ancestral wolf. So you just have to tweak and twist the correct knobs in them a little to bring out the real monster out in just a whistle
