@muley I think that allowing your "dog to holler" is not a good solution and could result in even more problems. It's not about allowing your dog to win but rather finding ways for you and your dog to live comfortably together. Dogs with separation anxiety do not always get over it. If this were me I'd be working with a certified dog trainer for solutions that are kind and support bonding with my dog.

My brother used the above website to find a certified dog trainer to help him with his puppy. He was very pleased with the assessment and suggestions offered by the trainer. The cost was reasonable and the training suggested has helped enormously with his puppy who is now amost 2 years old.
