There is no doubt that grapefruit is one of the most popular fruits in the world. As well as being one of the most popular dog treats, it is also one of the most nutritious ones. Besides being very high in vitamin C, the fruit is also very high in potassium. The pomelo is a type of citrus fruit that is similar in appearance to a grapefruit in terms of its appearance.  As you can see from the picture, the fruit's flesh has a pale color and is very juicy. I would describe its taste as a cross between a grapefruit and an orange - it is slightly sweet and tart simultaneously. The pomelo fruit is trendy in Asia and is often used in salads and as a garnish in Asian cuisine.
