If you've come home to a chewed-up doorframe, a neighbor's note about nonstop barking, or a puppy who's genuinely trembling the second you pick up your keys, you're not dealing with a "bad dog." You're dealing with separation anxiety in newly adopted puppies, and it's one of the most common — and most fixable — struggles new pet parents run into. The word "cure" gets thrown around a lot, but what actually works is steady, structured management that shrinks the anxiety down to something manageable, often disappearing almost entirely with consistency.
