Plain canned pumpkin is the healthiest choice for your dog. Both fresh and canned pumpkin are good sources of nutrients and fiber, but canned pumpkin contains a higher concentration of fiber and nutrients compared to fresh pumpkin. This is because fresh pumpkin has higher water content than canned pumpkin. However, canned pumpkin with added salt, spices, sugar, or other additives can irritate your dog’s stomach further, counteracting the beneficial effects of the pumpkin.
Note that you should NEVER use canned pumpkin pie, as it may contain xylitol, which is toxic to dogs.
