The English Springer Spaniel is a medium sized dog. Adults generally stand 18-22 inches tall (from ground to shoulder) and weigh around 50 pounds. Their size makes them ideal for transportation and living in smaller homes (as long as they get adequate exercise).
The breed does well with children (especially if they are introduced to kids while a puppy) and do well with other dogs. However, since the English Springer Spaniel is a hunting dog they will have a strong prey instinct which can be an issue for families with smaller pets. English Springers usually don't make the best guard dogs since they will quickly warm to any stranger that gives them attention.
English Springer Spaniels are a moderate maintenance dog. They require adequate exercise and generally need 30-60 minutes of activity daily to help them dispose of their energy. The breed sheds year round, but brushing their coat three times per week will keep their coat clean and most of the hair off your clothes and furniture.
