Male red merle Australian Shepherd puppy

Male Australian Shepherd puppy looking for a good home. He's a red merle. He is about 16 weeks old. He is not fixed. Very playful and sweet, he is currently working on potty training and doing quite well! He'll let you know when he needs to go out. He's great with children, but he's still a puppy, so he jumps and chews! I'm looking to rehome him for $500.
