As with humans, animals’ nutritional needs change according to age. As our pets get older we must be alert to change their diet to fit and meet those needs to help them stay healthy and give us many years of companionship.
The dogs are considered old depending on their race (and size) at different ages. The veterinarian can help you decide if it’s time to change their food. But generally, we see that the animal is less active, often fat because of reduced activity, and will start to get gray hair. That is the best time to change your diet to one that meets the new nutritional requirements.
In the market there are many brands of dog food you can buy. It should contain Vitamins C and E to strengthen their immune system; Phosphorus to have healthy kidneys, sodium for healthy heart and vital organs, and should be easy to digest. I should also have less calories and fat, since the animal is not growing or burning them running as before.
