Congrats man. I have a lab/retreiver mix that looks the same except for solid white. She is 2 years old now and also named Harley because she picked her own collar out. She learns very easy. Only bad habit she ever had was she liked to try to eat my wifes hair or pull it. Also once she began to sleep with my she would bite my fucking face if she wanted out of bed, but she grew out of that after about a month.
