With all due respect, this is NOT a child you have, though you may love it just the same. I think people cause problems with their dogs by not recognizing that they ARE dogs first, then a breed, then a companion. Eventually, your dog will likely develop behaviour issues if you continue to treat it like a human baby and project your anxieties onto it.

IMO you should be training your puppy to be on its own without anxiety, for its own good. If you're really that afraid to leave your puppy alone for a little while, some psychological help might be in order. I'm honestly not trying to be rude by saying that. Perhaps you just have some issues you need to work on so that you can enjoy life without stressing about every little thing.
