Dog worm medicines are both inexpensive and easy to administer.  Many of them can be purchased without a prescription while several do require that you get a prescription from your vet.  There is also at least one dog worm medication that is all-natural.

What’s the difference between these dog worm medicines, and which one would be right for your dog?

First, there are dewormers and then there are other dog worm medicines that do more than deworm the dog.

There are also some differences between dewormers in terms of how often they must be administered.  For example, Wormout and Nemex-2 require just one dosage.  In comparison, Safe-Guard and Panacur C are to be given to the dog for three consecutive days.  And WormX Plus and Worm Clear are to be administered three times a day for one day.

Below are descriptions of the most popular dog worm medicines along with sample prices.  Please keep in mind these prices will vary, depending on whether you buy them online or at your local pet store, and which retailer you buy from.

Roundworm, Hookworm, Whipworm and Tapeworm Medicines

Sentinel Tapeworm Preventative

Sentinel is different in that it is the only monthly oral preventative that actually guards against heartworms, adult roundworms, adult hookworms, and whipworms; and that prevents the development of flea eggs.  It does require a prescription from your veterinarian.

Sentinel controls and prevents flea eggs from hatching.  This is important because if your dog consumes a flea that is tapeworm-infected, it will eventually have a tapeworm.  This is because when the dog digests the flea, the tiny tapeworm inside it is released into the dog’s system and ultimately grows into a worm that can be six to nine inches long.

Sentinel comes in palatable, flavored tabs.  It also eliminates the tissue stage of heartworm larvae and the adult stage of hookworms, roundworms and whipworms.  Recommended dosage is once a month in the dog’s food.

  • For dogs 2 to 10 lbs., 6-pack flavor tabs $55.00
  • For dogs 11 to 25 lbs., 6-pack flavor tabs $57.00
  • For dogs 26 to 40 lbs., 6-pack flavor tabs $63.00
  • For dogs 51-100 lbs., 6-pack flavor tab $68.00

D-Worm for Tapeworms

D-Worm is used specifically to rid dogs of tapeworms.  Tapeworms are different from the other intestinal worms in that infection comes when the dog consumes a flea – and not because of eating feces, inadvertently consuming worm-infested soil or eating an infected prey.  D-Worm kills both the flea-transmitted and rabbit transmitted species of tapeworms.  It is available online, requires only one dosage, and does not need a prescription.

The recommended dosage of D-Worm is:

  • 1-5 lbs. 1/2 tablet
  • 6-10 lbs. 1 tablet
  • 11-15 lbs. 1 tablet
  • 16-30 lbs. 2 tablets
  • 31-45 lbs. 3 tablets
  • 46-60 lbs. 4 tablets
  • Over 60 lbs. 5 tablets

All-Natural Dog Worm Medicine

If you are concerned about giving your dog a harsh dewormer, there is all-natural alternative called HomeoPet Worm Clear.

The manufacturer of this product claims that Worm Clear is a fast-acting, broad-spectrum, 100% natural liquid homeopathic product that will remove hookworms, roundworms and tapeworms.  It is also said to help prevent infestations by reducing the dog’s susceptibility to worms.  It can be administered by adding it to the dog’s water or directly into its mouth.  Worm Clear has no added chemicals and, according to its manufacturer, is a gentle, safer alternative to most dewormers.

You give Worm Clear to the dog to three times a day – in the morning, the evening and at bedtime.  The dosage for dogs less than 20 pounds is five drops; for dog 20-100 pounds, 10 drops; and for pets over 100 pounds, 15 drops.  To prevent worm infestations, the product should be given to the dog for seven days.

15 mL bottle $12.49
