Hello, I really love my blue heeler dog. He is so fun to play with. Do you have a dog?
I love blue heelers they are so smart and high energy 
Yes, he loves to get lots of exercise. They were bred to her cattle which explains their high energy level!
It's said they are great for training and find it interesting the more challenging it is...is that true?
Yes, he has trained very well. He knows how to heel well and will sit and stay on command. He can tell the difference between friend and foe as well.
that's amazing he's a family pet and a guard dog
He is part dingo which comes out when he sees someone approaching he doesn't know. He is wary of strangers and I have taught him a command to act aggressive as needed.
part dingo? he sounds like my nephew dog tango he's tan in color we call him derpy
