I have had 3 on the list and agree they are great. Have had Belgian Sheepdog, Belgian Tervuren and German Shepherd.
In case you want to doggie ping.
Of course the Shepherd is at the top - though I prefer Shepherd/Malamute with a bit of Wolf mixed in... That’ll get you 125-150 lbs of holy terror... Not recommended unless you can be the alpha, and have a mountain range in the back yard to let them stretch out, but I guarantee you will walk the trails with every confidence, and sleep very well at night... Two is even better. and *nothing* will touch your kids.
I’ve had two German Shepherds and a Chow-got them as puppies, and they were still feared by strangers when they were really old-the Shepherds lived to 13 and 14 , the Chow to 17. I have to disagree with some of the breeds on the list, though-I had an Aussie for 15 years-her whole life-and although she was fantastic at herding just about anything, she was no watchdog/guard dog-she was too friendly. My Siberian Husky is almost 17, and is still a great guard dog-that breed is not even on the list...
German Shepherd deserves to be #1. Strong, loyal, and with an almost human brain . So are the other dogs you listed. Chow Chow? Wouldn’t trust one. Some of those hunting dogs, yeah. O.k.but not really in the same class.
Surprised the Neapolitan Mastiff.
