To summarize everything we looked at in this article, most dogs will not need a special senior dog food to live a healthy life. If your dog has been eating a certain kind of dog food for years, there's no reason to switch them to anything else just because they're older.
When should a dog eat Senior dog food?
That's around the time that your dog's activity level may begin to slow down, and his metabolism may begin to decrease. His brain may also become less efficient at metabolizing glucose, which can lead to memory problems. Around age seven, you may want to think about switching him to a dog food for older dogs.
What should you feed an older dog?
Offer your dog fruits and vegetables. All dogs benefit from eating small amounts of fruits and vegetables, particularly when they're older and more prone to constipation. Add fiber to your dog's diet in the form of wheat bran, steamed fresh green beans or canned green beans, or plain canned pumpkin.
