Passion fruit is safe for dogs
Passion fruit is safe to eat and is a good source of vitamin C, riboflavin, niacin, and iron. As with other fruits, only feed it in moderation since it is high in sugar and may cause diarrhea. Make sure to only use ripe fruit and to not feed the skin since it contains compounds that can be broken down into cyanide. This can be toxic in large amounts and is more of an issue with unripe fruit.
