Photo 11 looks like my big boy, Baxter. He’s a German Shepard terrior something mix (from a shelter). He doesn’t like other dogs or cats; is incredibly protective of our family and thinks he is a lapdog. The funny thing is he bumps into things w/his rear end all the time. He doesn’t sense his body is back there.
Mutts (no matter their size) are the best :)
#11 is an Irish Wolfhound, tallest breed, or at worst a Scottish Deerhound. But he just looks too buff for a SD.
I've had 2 very large Golden Retrievers. Both were house dogs, and my house has a lot of antique furniture, so space is at premium. Neither dog EVER knocked over anything. They were amazingly graceful while weaving between furniture legs, etc. The only thing I had to watch for was the tail An excited Golden can sweep your coffee right off the coffee table with their tail.
