Unless your puppy is showing signs
of true separation anxiety (and this is rare in young puppies), simply ignore the complaints during the day.
Cesar's Way, the online resource of the «Dog Whisperer» Cesar Milan, there is two types of separation anxiety in dogs: Simulated and
true separation anxiety.
It's important to remember that
true separation anxiety can be caused by a number of reasons.
If you really do suspect that your dog has
true separation anxiety, it is important to first rule out other causes of behavior.
True separation anxiety is typically characterized by a dog that causes real property damage (chews holes in the wall, rips apart a sofa, etc).
Fourth, are the dogs with
true separation anxiety.
Simulated vs. true dog separation anxiety There is
true separation anxiety, and there is simulated separation anxiety, in which the dog behavior appears to be separation anxiety but it is, in fact, a learned behavior.
True separation anxiety is typically seen in dogs that have been passed around from home to home or rescued from a shelter or the street.
True separation anxiety, on the other hand, causes the dog to experience real stress during the absence of his owner.
