Hello I have just adopted a 5 month old puppy he is a staff/husky cross. His previous owner had no rules for him and let him sleep with her in the bed. My fiance and I have puppy pads and crate but he goes insane when left alone at all. He has ripped our carpet just when we left him in the other room. How long do we leave him crying for in the crate at night ? Also any other tips would be grateful !!
