Prescription Worm Medicine for Dogs

Help your dog kick parasites to the curb with parasite & deworming medicine. Chewy has a great selection of worm medicine for dogs, including tapeworm medicine, roundworm and hookworm treatment, and ringworm medicine. We also have several combination products that get rid of several types of worms at once.

Most types of prescription worm medicine come as oral medications in tablet, chewable tablet, or soft chew form. Many treat tapeworms, roundworms, hookworms and whipworms, as well. These treatments can protect for a month or more and help break the cycle of parasite reinfection. Younger dogs may need a special puppy worm medicine, or an adult medicine in a smaller dose.

In addition to deworming pills, you can get prescription parasiticides to treat conditions like mange and ear mites. Some of these are long-acting topicals that protect against fleas and ticks, too. Dogs with ringworm will need an antifungal medicine and not a dewormer, since ringworm is not actually caused by a worm.

Perhaps one of the most important prescription medicines you will need for your dog is a heartworm preventative prescribed by your vet. See your vet for a heartworm test and a prescription and remember to give your dog his medication year-round. You can find everything you need to keep your furry friends healthy in the Chewy pet pharmacy. Shop for dog parasite medicine, worm medicine for cats, preventative flea and tick products and everything else to keep your best friend pest-free and feeling healthy.

Frequently Asked Questions about Prescription Worm Medicine for Dogs

How do I get dog parasite and deworming medicine prescriptions online at Chewy Pharmacy?

Get dog parasite and deworming medicine prescriptions online at Chewy Pharmacy by first visiting your vet for an exam and necessary tests. Your vet can then prescribe medication for you to order online from our pharmacy. Simply add your pet’s name and vet information at checkout and we will contact your vet for the prescription. That’s all you need to do to order your dog deworming and parasite medicine prescriptions from Chewy!

What is dog dewormer?

A dog dewormer treats roundworms, hookworms and whipworms by paralyzing and killing them, while tapeworms are killed and then broken into smaller sections, so your dog can then pass them. Some parasites, like hookworms and whipworms, are so small you may not see them in your dog’s stool at all. That is why you should visit your vet regularly and have her perform an exam and test your dog’s stool for parasites.

What prescription dog deworming and parasite medicine is best?

The best deworming and parasite medicine for your dog will depend on which parasites or worms he has and what other problems you want to prevent or treat. Preventatives like Heartgard and Interceptor Plus protect against heartworm and treat and control intestinal worms, as well, while NexGard and Bravecto protect against fleas and ticks that can carry canine parasites. You can also buy standalone dewormers and targeted treatments for problems like mange, mites and ringworm. Ask your vet which products might be best for your dog.

Does dog dewormer cause diarrhea?

Dewormers can cause diarrhea and frequent defecation is a common side effect, too. The symptoms usually pass within a day or two and your pup should be back to eating normally by then, as well.

How do I set up Autoship for my prescription dog parasite and deworming medicine?

Set up Autoship for your prescription parasite and deworming medicine by choosing Autoship when you check out. Then, select your delivery frequency—you can always cancel or change this at any time. You must have a valid prescription or refill on file for Autoship to occur. If you do not have a prescription, or if your prescription is close to expiring, one of our team members will contact your vet to obtain the necessary information. Autoship makes getting deworming and parasite medicine for your dog fast and easy!
