Dog Dewormer Vs Wormer

Before I get into talking about anything else, let me clear the confusion about the naming.

Although both are used interchangeably, the wording is much more worrisome.

A dog dewormer is a medicine that you use to deworm your dog.

That is to say, clean worms off of him.

This is good, respected dog owner behavior.

However, “dog wormer” is the opposite.

If you ask your vet to give a dog wormer, I wouldn’t be surprised if they take your dog away.

So, please, try to stop yourself from getting a “dog wormer” and help your dog become healthier by purchasing a dog DEwormer.

How to Tell if Your Dog Has Worms

How Do Dogs Get Worms?

You may think knowing the answer to this question will help you stop your dog from ever getting worms.

However, it won’t.

There is almost nothing you can do about how your dog will get worms, except for one thing or two.

As a puppy, worms will be transmitted from the mother to the newborn dogs through the placenta.

These are intestinal worms that are transmitted before the puppy is even born.

Other worms will be transmitted through the mother’s milk in the first weeks.

As you may have guessed by now, pregnant dogs usually have worms.

Some vets may recommend deworming a pregnant dog, but it usually isn’t that big of a deal (depending on what type of worm we’re talking about).

Older dogs will likely catch these worms by unintentionally finding them.

If your dog likes to play catch will smaller pets such mice, there is a chance he will be infected.

Also, if he eats feces of other dead animals, some parasite eggs may be laying around, and he’ll probably eat them.

However, just playing in the dirt is a possible way for your dog to catch a few worms.

That’s why it is basically up to your dog to stop himself from the infestation.

In other words, you have no say in it before it happens, but you can easily solve the problem even before it is a problem.

Learn more about worms from these 10 facts that you probably didn’t know.

Types of Worms

There are mainly six types of worms that your dog is most likely to encounter in his lifetime.

As said before, there isn’t much you can do to stop the infestation from happening, but you can easily treat it.

However, we cannot emphasize enough on how fatal these worms can be on both your dogs and yourself if not treated.

Rather than diarrhea and coughing, these worms could kill your dog.

If they are passed onto any other human, they can do just the same.

That is why deworming your dog is important, whether symptoms are showing or not.


The only way your dog can get infected by heartworm is through a mosquito bite.

There is no way to know whether a mosquito is infected or not.

So, you just have to prevent the growth of this type of worms whether you think your dog is infected or not.

Heartworms can grow to be up to 14 inches long (are you scared now?) and will live in your dog’s heart.

They affect the functions of the heart and the clotting of the blood.

If left untreated, your dog may die within days of infestation.

Please never use over-the-counter dewormers to treat heartworms!

These parasites suck the blood of your dog to the point of killing him.

Usually, hookworms are transmitted through the mother’s milk as they are most common in newborn puppies.

If left untreated, they can be deadly.

Hookworms usually invade and inhabit your dog and start growing inside of him.

However, you can easily get rid of them after two or three rounds of deworming.

So, there is no need to be (too) worried. Chances are your dog will survive.

These worms also live in the intestines of your puppy and are transmitted mostly through his mother.

Fully grown, these parasites look like spaghetti and are noticed in your dog’s poop.

If you see them, please pick up your dog’s poop as carefully as possible and show it to your vet.

The roundworms can be fatal to puppies as they eat the food he receives from his mother.

They can also produce more than 80 thousand eggs a day.

However, getting rid of them is easy as soon as you notice them.

It is also good to think of prevention by always cleaning where your dog plays.

Your dog is most likely to get infected by tapeworms if he swallows fleas that carry them or licks himself too much.

They suck some nutrients from the intestine they are attached to and slowly cause your dog diarrhea.

They are relatively small in size, averaging at a length of a grain of rice.

The life cycle of a tapeworm keeps repeating itself as they break into segments.

These segments contain eggs that your dog (or another pet) will become the host for.

Just like the rest of the worms above, whipworms will live in your dog’s intestine and suck his blood.

They can live in the dirt for years until a dog comes and ingests them.

They can also be found in feces of animals and other pets.

You will know your dog is infected by a whipworm when he starts to have bloody diarrhea.

Usually, the vet will be able to prescribe dewormers for your dog that will kill the worms and their eggs, too.

Symptoms of Worm Infestation

Just like with all infestations, there are some apparent symptoms that can tell you that your dog may be sick.

Noticing these symptoms early on can be lifesaving for your dog.

However, it should be noted that not all worm infestations have apparent symptoms.

Some stay hidden until it’s too late to save your dog. So be careful.

No Symptoms

I would like to emphasize on this before moving on.

Your dog not having diarrhea or vomiting does not mean he doesn’t have any worm infestations.

Chances are he does no matter how clean your environment is.

Therefore, you should always work on a deworming schedule with your vet.

That will keep your dog clean and safe for the rest of his life.

You don’t have to worry about worms then as they are usually killed before growing inside your dog.

You should also know that they can mean more than that.

Therefore, if any of these symptoms can be seen, it is best to check with your veterinarian. They will have more answers for you.

Here are the symptoms:

How to Deworm Your Dog

It is relatively easy to deworm your dog when the worms haven’t yet grown inside of him.

However, the dewormers may not fix ALL worm infestations your dog may or may not have.

The medication is usually effective with several types but not all of them.

Therefore, for better care, you may find yourself using more than one medications. This is not recommended without prior consultation with your vet.

Watch the video down below to see how you can give your dog his deworming medication.

Basic Deworming Schedule

Puppies should be dewormed as soon as they are two weeks old; once every two weeks until they are 3 months old.

3-month-old puppies should be dewormed once each month until they are 6 months old.

After that, once every 3 months should be enough.

You should know that this schedule is only to keep your dog as safe as possible.

If you see signs of worm infestation, it is best to take your dog to the vet.
