Older, more mature Cocker Spaniels enjoy a good 30 minute brisk and interesting walk twice a day and they like nothing better than to spend as much time in a garden as possible. Working Cockers need a lot more in the way of exercise and mental stimulation to be truly happy, but both show dogs and working dogs enjoy playing interactive games with their owners as often as possible. One thing to bear in mind, is that it is never a good idea to let Cocker Spaniels off their leads when they are around livestock.
