I’ve always had medium sized mix breed dogs.
Last ‘breed’ dog I ran across was a full blood pit named Daz that was as smart as a brick, but extremely cuddly.
Though overly excitable, all you had to do was look at him, and he’d leap straight up and down because the humans were looking at him, and he liked people.
Didn’t matter if he was under the table when you saw him, you’d hear his head knocking a hole in the tabletop as he happily hopped under there.
We had a red and white Siberian husky that was like that. They aren’t normally watch dogs, but this guy always got between me and whoever was at the door. I loved his ol’ stupid self.
He was raised as a show dog, so we had to teach him to play, and also teach him to “sing” for a “cookie.” Now THAT was funny!
