Miralax For Dogs: Uses, Dosage, & Side Effects

Miralax is a laxative that can primarily treat constipation in dogs. While the term is used colloquially, It’s actually the brand name of medicine known by the generic polyethylene glycol 3350. The medication works on a short-term basis by helping the dog’s stools retain more water, which in turn makes them easier to pass. Here’s what you should know about the uses, dosage, and side effects of Miralax for dogs.

Uses Of Miralax For Dogs

Veterinarians normally prescribe Miralax for dogs to treat constipation. It works by allowing the dog’s stools to retain more water, which makes them easier for the animal to successfully and painlessly pass. In the medical world, the drug is known as an osmotic laxative, which uses the water already present in the body to unblock the digestive system, rather than relying on stimulants. The medication can also clear out a dog’s intestine before the animal undergoes an examination.

You don’t need a veterinarian’s prescription to purchase the medicine, which comes in powder or liquid form. However, you must always consult with your vet before adding it to your dog’s routine. Closely follow your vet’s instructions for the correct and safe dosage and frequency.

Dosage Of Miralax For Dogs

Your veterinarian will prescribe a dosage of Miralax that reflects the severity of the constipation and the size and weight of your dog. It’s important to always follow your vet’s dosage and administration instructions exactly. This includes the length of time you should give the medicine to your dog.

While Miralax and similar products are available over the counter, we highly recommend speaking directly with your vet rather than referring to websites for at-home dosing information. Some dogs may have allergic reactions or the medication could interfere with dogs with toxic colitis or gastric retention, as well as ones who are pregnant or nursing. Your vet can determine the safety of the medication and dosage for your dog before administering it.

Side Effects Of Miralax For Dogs

Side effects of Miralax are uncommon in dogs, but sometimes nausea, vomiting, and general lethargy can occur. In general, if you notice any sort of allergic reaction, including hives, swelling, or difficulty breathing when your dog takes any kind of medicine, make sure to contact your veterinarian immediately.

If you suspect your dog took too much of the medication and might be suffering from an overdose, contact an emergency veterinarian right away. An overdose could lead to pancreatitis.
