As far as I’m concerned my miniature schnauzer is one smart cookie.
My sisters dog, a basset hound, is dam sure the dumbest thing I’ve ever seen.
Had an Irish Setter when I was a kid....beautiful, but totally the dumbest dog on earth......
I have a miniature schnauzer as well and agree that it's a very smart breed and very friendly too - although considers herself the center of the universe. I also had a basset hound which lived to be twelve and then had to be put down due to crippling arthritis. he, god bless his soul, was dumb as a brick but equally friendly and lovable. He was a loyal and gentle friend for my children while they were growing up.
I have 3 basset hounds. And, if you look at life from their point of view, they are pretty darn smart. They get EVERYONE to feed them, including a couple of neighbors. It seems everyone in our neighborhood walks by to say hi to the silly hounds, so they get a lot of attention. And soft, warm beds.
