Buying Guide

What Worms Should You Target?

When puppies are young, it is a good idea to deworm them for a variety of parasites as a preventative measure. The most common worms that puppies pick up from their mother or their environment are tapeworms, roundworms, and hookworms. Selecting a broad-spectrum dewormer that targets these parasites and others is a way to ensure that your puppy is sufficiently protected against an infestation of worms and the illness that can cause.

If your dog is vomiting long, white worms, or you are finding them in your dog’s stool, then you need to select a dewormer that targets roundworms. Dogs who have small, pale things that look like sesame seeds near their rear end or on their beds should be treated for tapeworms, as these are the segments of tapeworms that indicate an infection.

When a general remedy does not resolve your dog’s symptoms, it may warrant a trip to the vet to check for other parasites that are not able to be treated at home, such as giardia or coccidia. Unfortunately, some intestinal parasites must be treated with prescription medication. These are less common than the parasites you are likely to run into, so it is recommended to start with a broad-spectrum dewormer as long as your dog is eating and acting normally.

It is important to note that, though it has “worm” in the name, dewormers do not work to prevent heartworm infections. This parasite is extremely dangerous and has a high fatality rate, so it preventing it with the appropriate medication from your veterinarian is key.

When Should Dogs and Puppies be Dewormed?

Puppies should be dewormed multiple times as a preventative measure, and it is recommended to deworm puppies at 4 weeks, 6 weeks, and 8 weeks old. Dogs should have annual fecal examinations done with their veterinarian to determine if they need to be dewormed as adults when there are no symptoms of intestinal parasites. In the presence of symptoms of a worm infestation, it is recommended to deworm your dog proactively.

Symptoms of intestinal parasites can vary between individual dogs, even when two dogs are suffering from the same type of worm. Ultimately, the symptoms that dogs experience and those that they display stem from two detrimental aspects of having intestinal parasites: malnutrition caused by the worms utilizing all of the food consumed, and increased parasite load caused by the worms being able to multiply in your dog’s digestive system.

Signs you should deworm your dog include:

  • Weight loss despite an increased appetite
  • Pot-bellied appearance with a rounded abdomen
  • Vomiting that may contain visible worms
  • Diarrhea or stool with visible worms in it
  • Small “sesame seeds” on their fur or where they sleep
  • Dull, thinning, or greasy haircoat

Which Deworming Medications are Best?

When deciding which dewormer will be best for your dog, looking at the ingredients is a step that can’t be skipped. Inspecting the ingredients list is the best way to determine if a product will be effective against intestinal worms, and it is vital in saving you from wasting money and your dog from suffering a prolonged infestation. Products that contain the same active ingredients that can be found in prescription dewormers will provide more efficient parasite management.

Praziquantel is one of the best treatments found in prescription products and is effective against tapeworms and other parasites. Its efficiency against parasite infestations comes from its targeting of newly-hatched larvae which results in the worms not being able to reproduce and multiply in the GI tract. It can also be used to treat certain blood worms and liver worms when prescribed by a veterinarian at an appropriate dose.

Roundworms, hookworms, and pinworms are treated with pyrantel pamoate, an antiparasitic medication found in many over-the-counter as well as prescription remedies. This medication causes a paralysis of the worm that causes it to lose its painful grip on the lining of the intestines, allowing the worms to then pass out of the digestive system quickly. Pyrantel is poorly absorbed by the lining of the digestive system, making it safe to use in animals.
