I just got my 3 month old male puppy and don't know where to start I have already enrolled him in a class at the local petco. Where do I start he seems to be a little shy because all he does is sleep at the moment, I tried to walking him today but all he does is stand still and pull. I plan on researching more information on leash training and give it another go tonight. Do you guys have any advice on what training or things I should do with my puppy to get him more active and confortable at his new home. Thanks guys !
