Important Features To Consider For Picking Best Dog Dewormer

Important Features To Consider For Picking Best Dog DewormerDog dewormer should effectively remove your puppy’s worms. When selecting a dog dewormer, there are a few factors to consider:

Active ingredients

There are several ingredients that are used alone or in combination with others. Not all formulas work on every type of worm. For example, dewormers with fenbendazole don’t eliminate tapeworms that come from fleas, while piperazine only works on roundworms.

How to administer the dewormer

There are a number of ways to give your dog an anthelmintic, and which one you choose is a matter of preference. Many dewormers are offered in the form of a chewable pill that is often flavored to keep your dog’s taste buds happy. Others come in liquid form and are administered through a dropper, directly into the mouth or by adding it to your pup’s food or water. Some dewormers are available as granules to be added to food or water.

Targeted parasites

It makes no sense to give your dog granules or pills that don’t work. Most products list the eliminated worm species. It’s important to note that there are two types of tapeworms, and many treatments don’t offer both. The seven most common worms are tapeworms (Dipylidium caninum and Taenia pisiformis), roundworms (Toxocara cabins, and Toxascaris leonina), hookworms (Ancylostoma caninum, Ancylostoma Brazilians, and Uncinaria stenocephala) and whipworms (Trichuris vulpis).

The number of doses.

Most deworming treatments are one or 3-day dosages, although some natural dewormers for dogs are intended to be used daily.

Future prevention

You don’t have to rely on dewormers to prevent or treat worms. There are other things you can do to get your puppy healthy. A cooked or raw prey diet provides the most species-specific diet. Probiotics and digestive enzymes can also help build gut health. The stronger your dog’s immune system, the more likely it is to prevent parasites.

Types of Worms Affecting Dogs

Types of Worms Affecting DogsThere are five different types of worms known to affect dogs, and they are all parasites that can spread quickly in the system. Parasites come in a variety of forms, but most that affect dogs are intestinal parasites: heartworms are the only exception. Here are the five different types of worms that are known to affect dogs:

  • Roundworms: These are the most common intestinal parasites seen in dogs, and there are two types, one more common in puppies.
  • Tapeworms: Dogs often get this type of intestinal parasite from eating flies or wild animals infected with tapeworms or fleas they carry.
  • Whipworms: This type of worm lives in the caecum and transfers its eggs to the dog’s feces: the eggs can survive in the right environment for up to 5 years.
  • Hookworms: These worms can cause anemia in dogs, which can be very dangerous, even deadly, in puppies if left untreated
  • Heartworms: Transmitted by mosquitoes, heartworms are extremely dangerous but too prevent parasite that grows and multiplies in the dog’s heart.

If your dog has a parasitic infection, he will not always show outward symptoms. In some cases, the only sign you see is eggs or segments that have passed in his stool. Your job as a dog owner is to pay attention to your dog’s condition so that you can catch the early warning signs of a problem.

FAQs About Dog Dewormers

What is a dog dewormer, and how does it work?

Dog dewormers treat parasitic infections from a wide variety of insects, including hookworms, roundworms, whipworms, tapeworms, Giardia, and more. These drugs target the worm to paralyze or kill it, and then the body expels it through the feces.

What are the signs of a dog with worms?

There are several visible signs of dogs with worms, although the symptoms vary from animal to animal. Paying attention to your dog’s environment is a good start, but it’s almost impossible to keep young puppies from eating dirt or licking their fur during fleas. It is important to monitor your dog for worms and watch for signs all year round.

Dogs with worms rub their butts on the floor, may have a swollen belly or parasites in their feces or vomiting. Some dogs have no appetite, while others eat but don’t gain weight. Pet owners find that their dog’s general appearance suffers, with issues such as dry hair and excessive shedding. Tapeworms are easy to spot because they are visible to the human eye. Owners see lighter colored spots under their dog’s tail, commonly referred to as white rice grains or sesame seed droppings. Others report noticing these spots on furniture where their dog sleeps.

How often should you deworm your dogs?

Regular, annual visits to your vet include the stool test, which looks for abnormalities and parasites. You only need to deworm your dogs if they test positive or show parasites. If you suspect your dog has worms, contact your vet for confirmation. Dogs with worms may or may not have symptoms, which is why the stool test is important.

How long does it take to get worms out of a dog?

Wormers go right into your dog’s digestive system where the parasites live. Most dewormers work immediately to paralyze and remove pests. Reviewers saw results ranging from 24 hours to 1 week. The amount of time depends on using the right product, treating it multiple times for major infestations, and preventing reinfection.

As long as you are using a dewormer intended for the diagnosed parasite, you will notice results within hours. Since larvae grow at different stages, retreatment may be necessary several weeks later. Almost all reviewers reported that the problems had disappeared within a week. Cleaning dog beds and furniture help prevent reinfection.


Dogs explore most of their world through their mouth. Unfortunately, this also exposes them to the risks of swallowing eggs that can turn into intestinal worms.

While there are some effective medications that will help treat them, you should definitely choose one that is effective for the worms that infect your dog. Be sure to read the above information carefully and always keep your vet informed when treating your dog for worms.
