Start by assessing health, behavior, and lifestyle fit. A basic vet check and a clear history (when available) matter more than pedigree for long-term happiness. Pay attention to how the dog reacts to people, noises, and other animals during your initial meetings.
Observe these practical signs:
Ask the shelter or foster about vaccination status, spay/neuter, microchip, known medical issues, and temperament in different settings. If possible, meet the dog in a neutral environment and do a short walk to gauge leash manners and recall. Bring family members and any resident pets for a supervised introduction.
Finally, consider practical logistics: space at home, time for exercise and training, budget for vet care, and whether the dog’s size and activity needs match your living situation. A good match reduces returns and improves long-term welfare for both of you.
