How can I get my puppy to stop whining and crying when we leave him alone?
Hi If your puppy has just come to live with you, he's probably scared and homesick. He wants to be with you, his 'pack', and it's natural for him to whine and cry if you leave him in his crate for example.
However, if he's getting plenty of love and attention, and is healthy, he needs to learn to accept being in his crate/exercise pen etc., at night or when you can't supervise him. In this instance, you just need to ignore his cries and complaints, and only take him out when he's quiet (or at least taken a break from whining, even if it's for a minute or two). Otherwise he will think crying gets him attention.
