Older people who buy dog food for their pooch and walk it on a regular basis may well be doing themselves a favour.
According to Emma Soames, editor-at-large for Saga Magazine, which focuses on the provision of services for people aged 50 and over, explained that walking is one of the best forms of exercise for those in later life.
She said: "The most popular form of exercise is walking because you don't risk hurting yourself in any way. If you walk briskly, you can get your heart rate up. A lot of people now say walking is the best sort of exercise for any generation."
Ms Soames added that other forms of exercise that are good for this age group are cycling and swimming, but revealed that walking is the "big winner".
Writing in the Daily Telegraph, vet Pete Wedderburn recently said that people who are busy with work should arrange a scheme so that they are able to share a dog with other members of the family, so that the pooch gets the attention and exercise it needs.
