Feeding a dog pumpkin seeds is one natural home remedy for de-worming. Organic, unsalted seeds are suggested for the best results. The recommended dosage is a teaspoon per 10 pounds of dog weight. Whole seeds or ground seeds added to the food as powder can be given once per day.
Garlic can also be used as an effective natural home remedy to de-worm dogs. Feeding a dog a half to two cloves of garlic per day can help ward off worms, as well as boost the dog's immune system. It is recommended that the garlic be minced or pressed and added to the dog's food once a day.
