Best dog laxative

Which dog laxative is best?

There’s nothing worse than being all blocked up, and there’s never an easy answer for loosening things out again. From the range of possible causes to the intimidating number of options, solving this problem for your dog can be complex, but don’t worry — it is doable.

The best dog laxative is the Vet Classics No Scoot Dog Supplement For Healthy Anal Gland Function. These chews are packed with natural ingredients, such as beet pulp and pumpkin powder, and the dosage instructions are simple and straightforward.

What to know before you buy a dog laxative

Dog laxative types

There are three types of dog laxatives:

  • Bulk-forming laxatives are the most commonly found over-the-counter. They’re packed with fiber which aids your dog’s digestive tract and helps your dog’s stool become softer and larger.
  • Emollient laxatives soften your dog's stool by helping it absorb more water. They’re particularly effective for dogs who've just had surgery, as it reduces their need to strain. However, emollient laxatives need to be prescribed.
  • Lubricant laxatives do just that, lubricate your dog’s digestive tract. This helps your dog pass stool faster and easier, and it also helps it absorb water to make it softer. However, it can affect your dog’s ability to absorb some nutrients, so it’s best used only occasionally.

Dog laxative forms

There are three forms of dog laxatives:

  • Chews are the most common form as they’re easy to administer and store. They aren’t always the yummiest, so if you have a picky dog, you may want to get one that’s flavored.
  • Kibble-like laxatives are small, dry pieces that you mix in with your dog’s regular food. Like chews, you may need flavored ones to get picky dogs to eat them.
  • Liquid and powder laxatives are the most difficult to dose, but they can also be the easiest to get your dog to take. All you need to do is mix them with water and add a splash of broth, and your dog should drink it right up.

Dosage quantity

Every dog laxative package contains a certain amount of doses, usually 40, 60 or 120. However, your dog may need several doses if they’re a large breed. You also need to consider how long you need to treat your dog, whether for a week or a new life-long regimen. Since dog laxatives don’t last forever, your goal should be to get only as many as you need. If you’re unsure of how many you need, opt for a smaller amount since you can always order more.

What to look for in a quality dog laxative


Dogs don’t like taking medicine any more than you do. Help them and you by getting laxatives with yummy flavors such as chicken, beef and cheese.


Dog laxatives must be carefully administered to avoid causing more digestive stress, not to mention to ensure it takes effect. The best laxatives have detailed dosage instructions, including how much to give and how long they need to be given. Some even include instructions or suggestions on actions to take if the laxative doesn’t work.

How much you can expect to spend on a dog laxative

They can cost as little as $10 or as much as $50. Basic laxatives typically cost no more than $15. Higher-quality laxatives can cost up to $25. Large packages of good-quality laxatives typically start around $20.

Dog laxative FAQ

What can cause constipation in dogs?

A. There’s a truly gargantuan list of reasons why your dog may be constipated, from diet issues or age to medication side effects or an enlarged colon. If your dog is constipated, you should always take it to your veterinarian to establish the cause so you can choose the best treatment method, whether that be laxatives or something else.

How long does a dog laxative take to work?

A. That depends on the type of laxative and how bad your dog's constipation is. Lubricant laxatives can take effect in as little as six hours, but most other laxatives may not start working for 24 to 72 hours.

Can pregnant dogs take a laxative?

A. Most laxatives are safe for pregnant dogs, though you should check with your veterinarian before giving your pregnant dog any kind of laxative.
