Best Dog Dewormer Summary

What is a Dog Dewormer?

What is a Dog Dewormer

A dog dewormer is a medication used to kill worms in dogs. It can be used to prevent and treat worm infestations. Worms are internal parasites that live in the dog’s intestines. The most common types of worms are roundworms, tapeworms, hookworms, and whipworms.

Dog dewormers come in various forms, including oral tablets, flavored chewables, and liquid suspensions. Most dog dewormers are broad-spectrum, meaning they work against different worms simultaneously.

Some deworming products are over-the-counter, while others require a vet prescription. Anyway, we strongly recommend talking to your trusted veterinarian before using a dog dewormer.

What are the Benefits of Dog Dewormers?

The main benefit of dog dewormers is that they kill worms. This helps protect your dog’s health from all the potential complications that come with living with many worms in the gut. These complications include dehydration, low energy, and anemia.

Which is the Best Dewormer for Dogs?

Which is the Best Dewormer for Dogs

The best dog dewormer is the PetArmor 7 Way De-Wormer. It contains prescription-grade ingredients that make it very effective in eliminating worms with a single dose.

When selecting a dog dewormer, keep the following considerations in mind:

  • The Dog’s Age. Most dewormers have an age limit below which they can’t be used. You should therefore check if the dewormer you are choosing is suited for your dog’s age, especially if she is still a puppy.
  • Formulation. These days, most dewormers are chews or liquids for easy administration, but some tablet formulations still exist. Opt for the formulation that will be easiest for your dog to take without giving you a hard time.
  • Worm Type. Some dewormers are made to target one type of worm, while others target multiple types. Whichever one you choose, be sure to check that it works for the specific type of worm infection your dog has.
  • Efficacy and Efficiency. This refers to how well a dewormer works. Some dewormers work in as little as 24 hours while others work slowly, and some barely work at all. Choose the dewormer that suits your dog’s needs the best. For example, if your dog needs fast relief, a fast-acting dewormer is paramount.

How can I Deworm My Dog Naturally?

You can deworm your dog using certain foods, usually fruits, veggies, and seeds. Natural dewormers for dogs can be beneficial if used correctly. However, we recommend seeing the vet before using a natural or mainstream dog dewormer.

Natural dewormers that can help treat intestinal parasites and worms in your dog include:

  • Pumpkin Seeds
  • Food-grade Diatomaceous Earth
  • Cloves
  • Papaya
  • Turmeric
  • Wormwood

Home remedies for treating intestinal parasites and worms in your dog are effective but may take more time to kill worms than a dewormer medication. Also, in cases of heavy infestations, it is better to use a regular instead of a natural dog dewormer.

How do I know if My Dog Needs Deworming?

How do I know if My Dog Needs Deworming

Scooting and the presence of worms and eggs in the dog’s stool are the main signs your dog needs to be dewormed. However, ideally, you should not wait for these signs to appear – you must deworm your dog regularly, following a schedule suggested by the vet.

Let’s take a closer look at some of the signs indicating your dog needs to be dewormed.

  • Worms/Eggs in the Stool. The most obvious symptom of intestinal parasites in dogs is the visible presence of rice-like or spaghetti-like structures in the poop. In severe cases, they can be present in the dog’s vomit. If possible, capture the worm or take a picture of it and bring it with you to the vet’s office.
  • Scooting. If you notice your dog rubbing or scratching its rear on the ground, floor, or your furniture (medical term – scooting), your dog is probably infested with intestinal worms. Call your veterinarian and make an appointment.
  • Pot-Bellied Abdomen. Swelling of the abdomen is more common and easily visible in puppies with heavy worm infestations. Puppies can be born with worms, especially if the mother was not regularly dewormed during pregnancy.
  • Increased Appetite. Intestinal worms feed on the same food as the dog. Therefore, a dog with worms is likely to eat more than usual and still lose weight.
  • Weight loss. As noted, dogs with worms lose weight because the parasites are taking their nutrients. As the weight loss progresses, the dog may start feeling lethargic and lose interest in everyday activities.
  • Bloody Diarrhea. Diarrhea is a very common sign of intestinal worms – simply put, the presence of worms in the intestines affects the dog’s gut health and overall wellness. However, bloody diarrhea can indicate other issues, which is why you need to call the vet if your dog has bloody diarrhea.
  • Poor Coat Quality. Over time, as the worms feed on the dog’s nutrients, the dog will experience a deterioration in its skin and coat health. If your dog’s skin is dry and its coat seems dull and unkempt, chances are it is dealing with intestinal parasites.

Can I Deworm My Dog Myself?

Yes, you can deworm your dog yourself. However, you still need a vet’s help to diagnose and maybe even select the best treatment for your dog.

It is nearly impossible to know what specific type of worm is affecting your dog without a diagnostic test.

Some worms may be visible, but others are so small you can’t see them in fecal matter. You should therefore see a vet as soon you know your dog has worms for an official diagnosis and prescription.

How Often Should I Deworm My Dog?

You should deworm your dog every three months. However, the exact deworming frequency depends on the dog’s age and lifestyle.

For example, if your dog develops symptoms of a worm infection between doses, you should deworm it with the guidance of your vet.

Also, in puppies, you may need to deworm more often. Most puppies need a dose every two weeks until twelve weeks of age and then every month until six months of age.

Talk to your veterinarian about the right deworming protocol for your dog. The vet will take into consideration many factors and create an individually tailored deworming schedule.

How do I Give My Dog a Dewormer?

how di I give my dog a dewormer

You can put the dewormer directly into your dog’s mouth or mix it with food. If giving the pill with the dog’s food, mix it in a small amount and make sure your dog eats it entirely.

This applies to standard dewormers in the form of pills or tablets. Today, there are some new dewormer options, such as chewable treats or even liquids (which can be oral or topical spot-on treatments).

Make sure you read the instructions carefully before giving your dog the dewormer.

How Long Does it Take to Get Rid of Worms in Dogs?

In general, it takes around four weeks for the worms to get eliminated from the dog’s body. However, the exact timeframe depends on the type of worm and the dewormer’s efficacy. The severity of the infestation plays an important role, too – weaker infestations tend to clear faster than strong ones.
