A Dog's Life improves upon and adds to the base functionality of dogs in Skyrim in an immersive and intuitive way, whilst also providing control over the mod's wide range of features. Basic new features include trading, home assignment, naming, and petting. More advanced features include dog harnesses, fetching items and dog tracking.
For those looking for an even more immersive experience, you can enable the needs features, including Happiness and Hunger. This means you will need to keep your dog happy by playing ball and giving regular pets, alongside feeding your pooch to prevent starvation.
