Dogs rarely get constipated unless it’s associated with another condition, such as arthritis, liver or gallbladder issues, parasites, or a side effect of medication.  The same goes for the majority of herbivorous animals, such as horses.  Cats, however, can develop a condition called Megacolon that results in severe constipation (obstipation). Some pet fish are also prone to constipation, such as laterally compressed species.

“Normal” constipation is usually treated with an enema, but surgery and/or medication may be necessary for chronic obstipation.  There are natural treatments for constipation in pets, which can be used alone or in conjunction with clinical treatments.  Like most natural pet remedies, these treatments have not been widely studied and should only be administered under the guidance of your veterinarian.

Natural Remedies for Constipation in Pets


Pet Food & Water – Poor quality pet food usually contains poor quality (or too little) protein and/or too much fat, which can cause constipation in any pet.  Research your pet’s optimum diet to ensure your pet food contains the appropriate ingredients and nutritional balance.  Water is very important for all body functions, including digestion.

Probiotics – Often all it takes to treat constipation is a bit of plain, active yogurt, three times per day. It can be mixed into food or fed directly if your pet will eat it. You can take it up a notch with a mix of probiotic species in a natural Probiotic pet supplement.

Fibrous vegetables – Dogs will usually eat at least some fibrous vegetables without too much coaxing.  Cats aren’t big fans of vegetables and normally they don’t require them.  However, vegetables that are low(ish) in carbohydrates, yet rich in fiber, can be highly beneficial for constipated cats and dogs.  Pumpkin and seaweed are often recommended as low-carb vegetable sources of fiber.  Brown and red seaweeds are especially effective in the treatment of constipation through the regulation of normal bowl function and gentle cleansing of the gastrointestinal tract with its mucilaginous substances (it even treats Irritable Bowl

Syndrome).  Seaweed is also a natural source of Taurine.

Other Roughage – Roughage doesn’t have to come from vegetable fiber.  Rehydrated freeze-dried Krill offers both roughage and optimum nutrition without straying from the carnivorous diet. It’s easily mixed into your pet’s regular food and they love the taste.  Pureed Sardines (unseasoned, packed in water or fresh) are another option.


The most effective way to get herbs into pets is by making a tea.  Cats or small dogs can have 1/4-1/2 tsp of strong tea per 15 pounds of weight.  Larger dogs can be given 1 tsp of herbal tea per 30 pounds of weight.  The tea can be administered 2-3 times per day.  These dosage recommendations are included in the book, Herbs for Pets, by Gregory Tilford and Mary Wulff.

Professionals often reach for Chickweed first when dealing with constipation in a wide variety of animals, including dogs, cats, birds, fish, horses, llamas, goats, etc.  It’s gentle, effective, and it soothes the digestive system.

The majority of herbs recommended for constipation actually focus on bile production and transport, such as Oregon Grape, Dandelion Root and Yellow Dock (also a laxative).  If constipation is attributed to a liver problem, a holistic veterinarian may recommend the short-term use of Milk Thistle, Licorice, or Turmeric.  Essential fatty acids can also be added to the diet to support liver function.

Colonic lubricating herbs for pets include Marshmallow Root, Flaxseed, Psyllium Husks and Chickweed.

Fennel can be used to relieve gas or griping associated with constipation. Simply add a bit to your herbal tea mixture.

Laxative herbs (Anthraquinones) can cause a great deal of discomfort in the bowl because they stimulate peristalsis (muscle contractions).  We strongly recommend a trip to the Vet if constipation is so severe you are considering natural laxatives.  Having used a natural laxative for myself, I can attest to the pain they can cause.  They should only be used when absolutely necessary and should not be used on pregnant pets. Natural laxatives include Yellow Dock, Aloe, Cascara, Sagrada, and Senna. Yellow Dock is recommended as the most gentle of the herbs containing Anthraquinones.

Note:  When using dried herbs for constipation, either make a herbal tea or rehydrate the herbs before feeding.  It’s important to use only fresh or gently dehydrated herbs for optimum effectiveness.  We rely on Starwest Botanicals for premium, human-grade herbs, essential oils and nutraceuticals.

  1. I started watching my constipated dog and realized he wasn’t drinking much at all. Now I give him pupsicles so he gets more water and I make sure the ingredients are good for digestion. Thanks for the new ideas.

  2. People don’t often consider doing something to treat constipation in their pets. Thanks for this advice. I’ve been searching around for different natural cures for constipation – and this is the first article I’ve come across that deals with pets. Good stuff.

  3. We give our dogs and cats seaweed and our dogs get other vegetables. They always have lots of fresh water and I think that might be the most important thing of all. Great article!

  4. pet food is full of chemicals and fillers that can constipate pets and cause other problems. switch to real food for good digestion.

  5. Our dog was constipated for awhile after we switched to a raw meat diet. We added some vegies and it cleared right up.

  6. My cat had a problem with constipation and guess what it was?

    He hated the new litter I bough! HAHA!

    I finally figured it out when his old litter went on sale so I bought it again. They can be such fussy animals!

  7. Excellent and responsible coverage of natural remedies for constipation. It’s not common unless there’s another reason for it but it does happen. It’s good to be knowledgeable so you have something to suggest to a vet. A lot of vets don’t know about natural remedies so they’ll either be interested or they’ll be threatened by it. One way or another you’ll know what your options are.
