I just got my second Australian Shepherd. The first was show lines and gorgeous. He was beautifully raised around horses with perfect manners. I told him one time to leave the poultry alone and that was the end of it. But he was timid and 2 weeks after I got him, he started growling at my son, completely unprovoked, so I returned him to the breeder.
My new family addition is 1 year old and he is a monster. His feet are always 2 feet above ground. He chews like a destructive machine, he climbs on people, and gets up on the kitchen counter. He is ranch and cattle dog style with a hard coat, not fluffy, and he produces enough watts of energy to power a small town..
He's a brilliant dog. He's wicked smart, very bold, loves everybody he meets on sight, and adores praise. He follows me around like my shadow, hoping I will ask him to do something or give him a cuddle, any attention is good attention. He's learning fast and I adore him. He would be a lot better behaved if he had been raised better, but he is trying hard to figure it out and he is already much improved.
I suspect that Australian Shepherds are best for people who are planning to actively raise them correctly. Left to their own devices and without guidance or training, you end up with an out of control monster like my gorgeous Wyatt. I am so lucky that his first family couldn't take any more of the climbing and chewing. I got an excellent dog. Wyatt got an excellent home, but it hurts my heart to think of the other high powered dynamo pups who lost the puppy lottery and ended up with families who would not train and discipline. I wonder how many of them are put to sleep because they are going through life at 150 MPH and no one has given them direction.
