Weasley is a sensitive dog who experiences his emotions very intensely. Today, he seems constantly on edge and still struggles greatly to manage his excitement and emotions. When stimulated, he may jump on people or react impulsively: this is not bad behavior, but a sign that he still needs to learn how to channel his energy.
Once trust is established, Weasley reveals himself to be a very sociable companion, human-oriented and happy to share moments with his family.
To help him thrive, he will need calm, patient, and kind adopters. Coercive or force-based methods would be completely counterproductive and could worsen his discomfort. Weasley will progress through a respectful, consistent, and positive approach.
He also has a strong need for chewing and physical/mental stimulation. Regular appropriate activities, chew items, and enriching occupations will be essential to help him relax and regain better emotional balance.
