How to find and adopt a healthy and happy shelter dog
Make a list of breeds of dogs you might like to adopt.
This can be a pretty long list, as its just a starting point. It helps to know the sort of dog you are looking for before starting your search.
Do a bit of research on each type of dog. What are its energy levels? What are its general personality characteristics? This information can help you narrow down what types of dogs might be right for you and your family.
