Just wondering..cause i called Petco and asked about their puppy classes and they said around 6 months!! Wha?? I dont know.. that seems kind of old too me... Is it? I do know that his attention span will be very short at 8 weeks... but i dont think they are un-trainable until 6 months old.. Maybe i'm wrong though.. (wouldnt be the first time.. ..) I'm getting an 8 week old pup tomorrow.. when can i start training him..and what should i start with first? I want the basic commands.. Come/sit/stay/lay/leave it... etc..? Thanks!
