Pumpkin may have many benefits for dogs, including: 

• Digestion: Pumpkin’s fiber content can help with diarrhea and constipation. The fiber absorbs water, which can add bulk to stool and help firm it up. The fiber also produces fatty acids that can stimulate intestinal sodium and water absorption.
• Immunity: Pumpkin contains vitamins A, E, and C, which can help boost your dog’s immune system. Pumpkin can also protect your dog from free radicals and possibly help prevent infections.
• Eye health: Pumpkin contains vitamin A, which can promote eye health.
• Skin and coat: Pumpkin’s high moisture content can help with dry skin and contribute to a shiny coat.
• Weight loss: Pumpkin’s high moisture and fiber content can help with weight loss. You can try replacing a few teaspoons of your dog’s regular food with canned pumpkin, or up to half a cup for a large dog.
• Worms: Pumpkin seeds contain an amino acid called cucurbitin, which can help paralyze and eliminate worms from your dog’s digestive tract. Pumpkin seeds can also help heal wounds, kidney ailments, and urinary issues.

Pumpkin also contains minerals like potassium, copper, manganese, and iron, which play a role in cellular functions.
