That a blue heeler?
100%
They are. Very intelligent. A family friend owns one and it's like my best friend. Loves to play catch all day won't stop even when I throw the ball 100 times.
Too smart.
My last dog was a blue heeler and too smart for his own good. They get protective tho of their owners and space.
I own two pits now. One 100% American Staffordshire and the other is more of a mutt. Dalmatian, American Staffordshire and a few percent of other random breeds.
Very protective, also has a rather strong bite. Up to 400psi for the males, quite the power to size ratio.
