Cantaloupe, pumpkin, apples, watermelon and blueberries are safe for dogs. These fruits contain many of the vitamins and minerals dogs need for good health. Some nutrients found in these foods even help prevent serious diseases in dogs.
According to Pet360, cantaloupe is good for a dog's eyesight and contains compounds that help prevent cancer. Cantaloupe is a good source of fiber, potassium, niacin, folate, vitamin B-6 and vitamin C. Many people think of pumpkin as a vegetable, but it's actually a type of berry, making it a fruit. Pumpkin contains fiber and cancer-fighting antioxidants. It is also used to help relieve constipation and diarrhea in dogs.
Apples are a good source of vitamin C and antioxidants. Dogs should not have apple stems or seeds, but the fruit meat and skin are safe for canine consumption. Watermelon is a great summer treat for dogs because it contains a lot of water. It also has vitamins A and C, thiamin, lycopene and vitamin B-6. Blueberries contain a cancer-fighting compound called resveratrol. They also contain tannins, which help prevent infections in a dog's urinary tract.
Although these fruits are good for dogs, they are just one part of a balanced diet. Dogs need the right mix of vitamins, proteins, minerals and fats for optimal nutrition. A fruit-only diet does not meet a dog's nutritional needs.
