Constipation can cause abdominal discomfort for your dog, but natural remedies can usually alleviate the symptoms. The best natural constipation remedies for dogs are bulk-forming laxatives. These substances work by absorbing water and swelling in the colon, making your dog's stools softer and larger. The larger stool in the colon causes intestinal contractions and bowel movements. Always talk to your veterinarian when you change your dog's diet.


The high water and fiber content of pumpkin makes it a natural laxative for dogs. If using canned pumpkin, avoid varieties with added spices. Add a small amount to wet dog food; the amount to give varies based on your dog's size. Dogs lighter 25 lbs. should have 1 to 2 tsp., while larger dogs can have up to 5 tsp., depending on weight. Most dogs like the taste of pumpkin.

Wheat Bran

Wheat bran is loaded with fiber, a natural laxative. Not only will wheat bran produce a bowel movement now — it will help keep your dog's digestive system regular after the constipation symptoms end. Sprinkle 1 to 2 tsp. (depending on weight) on your dog's food twice a day. You can use oat bran in the same way.


Psyllium, a commonly prescribed laxative for dogs, is a natural fiber supplement manufacturers make from the coating of plant seeds. You can obtain a prescription for it or buy it over the counter. Mix the powder with wet dog food according to your veterinarian's instructions.

Good Habits

Good habits can ease and prevent constipation symptoms in your dog. Always provide plenty of water, since dehydration can often cause constipation. Poor diet can also lead to constipation, so give your dog high-quality food. Offer real meat and protein rather than grains and meat by-products. Keep an eye on your dog to prevent him from ingesting large pieces of bone or grass, which can obstruct the digestive tract. Adequate exercise will also contribute to your dog's digestive health.
