Hey guys, I recently got a Doberman puppy and I noticed that whenever someone is not near him, he whines and cries. I tried to leave him alone for a few minutes, but he just couldn't handle it and started barking. I'm not sure why he's doing this and if it's normal behavior for a puppy. He's only three months old, so I'm not sure if this is just a phase he's going through or if there's something wrong with him. Has anyone else experienced this with their puppies or does anyone have any advice on how to deal with it? I would really appreciate any help or insights you could provide. Thanks in advance!
