Best Overall Dog Dewormer

5/5 Product Rating

Excel 8-in-1 Safeguard is an effective dewormer that takes care of all four types of worms that dogs can contract. 

Safeguard is easy to give your dog and comes in easy to feed granules that can be easily mixed in with the dog’s feed.  The dosage schedule of this effective dewormer is one of the most popular aspects of this quality product.

You give the granules to your dog for three days in a row every six months and that is it. It can be given to pregnant and nursing dogs and puppies that are at least 6 weeks of age. 

Packaging is simple and comes in three packages that are very easy to open and dump in your dog’s food, one each day.  The important thing is to make sure that you give it for the three consecutive days or it will not have the same effectiveness.  

A tip for ensuring that your dog will eat the granules is to put them in the fridge for an hour or two before feeding it to your dog.  Doing this will ensure that it is odorless and tasteless so they won’t even know it’s there. 

The active ingredient in this dewormer is fenbendazole which is a broad spectrum ingredient against all types of dog worms.  If you notice your dog’s appetite is suddenly increased, they are losing weight despite wanting to eat everything in site or they seem lethargic your dog may have worms. This product works well as a preventative as well as treatment to eliminate worms and prevent re-infestation.

2. Sentry

Best Overall Dog Dewormer – Runner Up

4.9/5 Product Rating

Sentry is a well-known name in dog and cat wellness products. This dewormer for dogs takes care of 7 strains of tapeworms, hookworms, and roundworms; two strains each of roundworms and tapeworms and three strains of hookworms.

The two active ingredients in this product include praziquantel and pyrantel pamoate.  These chewable tablets make it very easy to give you dog since they think they are getting a treat.

This dewormer is meant for dogs and puppies that weigh between 6 and 25 pounds.  The one drawback to this product is that is does not work against whipworms. This is one of the reasons it is so important to know what type of worms your dog has. If it is whipworms you will need to get a medicine that eliminates them as well.

Puppies under 12 weeks old and pregnant or nursing dogs should not take this dewormer so if your pet falls into one of those categories they will need to use another dewormer like Safeguard above.  Your dog should experience no side effects from this dewormer.

The active ingredient in this product is praziquantel which eliminates all types of worms so you don’t have to worry about certain types still being there.  This dog dewormer has been FDA approved and comes with a dosage chart to get rid of the guesswork. 

Keep in mind that the length of time you treat your dog will be determined by the type of worms the dog has.  Tapeworm infestations involve two weeks of treatment whereas hookworms only require 2 tablets. This particular product is well-suited for large dogs and should not be given to small dogs.

Dog Dewormer Buying Guide

Dog Dewormer Buying Guide

Part of being a good, responsible dog owner is taking care of all aspects of your dog’s health. Making sure your dog doesn’t have worms and treating them if they do is one of the most important things you can do for your dog’s health. Since untreated worm infestations can cause a lot of potentially serious health problems this is something that you will need to do throughout your dog’s life.

Dogs can get a lot of parasitic infestations from fleas to mites to worms. Some of the parasites are external and reside in the dog’s fur or on their skin; others, like worms, reside in the intestinal tract and can cause bigger problems. Worms can affect your dog’s colon.

Dogs can get worms from ingesting the eggs that are present on the dog’s outdoor surroundings. Worm eggs can survive for as long as two years after the feces have been left. Most of the worms are taken in from eating but hookworms can enter the dog’s system through its paws. Puppies are often born with worms that they get from the mother and from her milk.
However your dog has gotten worms, the most important thing is to get rid of them in a timely manner to reduce the ill effects that worms can cause.

Types of Worms

There are many different types of worms that a puppy or dog can have. Below we have provided you with a list of the different worms along with some valuable information about each including the symptoms that the dog may exhibit with that particular type of parasitic worm.

  1. Tapeworms – Tapeworms are one of the most common worms a dog can get. Most of the dewormers on the market include tapeworms in the list of worms eliminated but be sure to look in the description of the dewormer to make sure. Some products are only for tapeworms so if that is the only worms your dog has, you could opt for a dewormer that focuses on those. Some of the symptoms you will see if your dog has tapeworms include pieces of tapeworm segments in the dog’s feces; your dog will scoot its rear end along the floor, excessive biting or licking of the anal area, seeing tapeworms under the tail or on the dog’s anus.

  3. Hookworms – These small, thin worms hook inside the intestinal wall. You can’t always see hookworms so the stool may need to be tested by a vet. Many offices will do fecal checks for a reasonable amount and not charge an office visit. Symptoms that may be present when your dog has hookworms include bloody stools, itchy feet, anemia, poor appetite, coughing if the dog’s lungs have hookworms, overall malaise, diarrhea, and other similar symptoms.
  4. Roundworms – roundworms can live inside your dog’s intestines for a very long time. Some, when left untreated, can grow as long as 6 inches. Round worms resemble noodles and can cause bloating and swelling of the stomach. Some of the symptoms of roundworm infestation include vomiting, potbelly, visible worms in the dog’s stool, diarrhea, lethargy, weight loss, poor nursing of puppies, and more.
  5. Whipworms – Whipworms are very hard to get rid of and impossible to see in the dog’s feces. The only way to diagnose whipworms is through a vet. Treatment for whipworms is possible and they may be easier to prevent than eliminate but if you get a broad spectrum dewormer, you can cover these worms too.

Things to Look for in a Dewormer

There are several different types of dewormers on the market to choose from. When you are looking for the right one for your needs, there are things you want to look for. We have listed these things below.

  • Price – Budget is important but you should not choose a dewormer based on price alone. Never look for the cheapest dewormer you can find. You want to focus on brand reputation and reliability more than price. If you’re only looking for cheap, you’ll get substandard results that won’t necessarily take care of the worms your dog has.

  • Safety – It is important to choose the safest dewormer you can get for your dog. If your pup has a lot of allergies you don’t want to give them a dewormer that can cause a problem for them.
  • Mode of Administration – There is several different ways a dog can take a dewormer. Some are tablets, some are granules, liquid-based and more. Think about which way is easiest for your dog to take his or her wormer and choose a dewormer that offers that type of application.
  • Type of worms – We can’t stress enough the importance of knowing what kind of worms your dog is dealing with. This information is crucial to choosing the right dewormer. If you just are not sure or can’t get a definitive answer, choose a general dewormer that takes care of all types of worms to be safe.
  • Size and weight – You also need to know the size and weight of your dog before you purchase a dewormer. Some dewormers are not suitable for dogs under or over a certain weight or age and you can make them sick if they are given this dewormer. If you are dealing with young puppies that have worms you will be better off taking the litter to the vet and letting the vet treat them unless they are over the minimum age requirement that the dewormer states on the package.
  • Pregnant or nursing dogs – If your dog is pregnant or nursing puppies it is important that you choose a dewormer that is possible for them to take safely. There are many dewormers on the market that are safe for pregnant and nursing dogs including a couple of the selections we have reviewed above.
