Pedigree.com offers a Select-A-Dog tool to help determine dogs that are suitable based on house type and lifestyle. Purina.com and IAMS.com also offer dog breed suggestions based on your submitted criteria.
On Pedigree.com, questions focus on three different areas: living space, people at home and activity levels. Those who live alone in small houses, have small gardens and work a lot are recommended to consider smaller breeds such as Yorkshire terriers and dachshunds. People with large properties, active lifestyles and older children may receive suggestions of breeds such as Labrador retrievers, sheepdogs and collies.
Purina.com focuses on the qualities of your ideal dog and lifestyle considerations. Lifestyle considerations include the hours the dog may be alone and the type of yard available. IAMS.com is another pet site that offers a dog breed selector. Considerations are appearance and behavior of your preferred dog, care requirements and activities.
