Best Dewormers for Dogs: Aspects to Consider About Products

Does Your Dog Have Worms?

As a dog owner, it is necessary to be aware of the different signs and symptoms that your pet might be infected.

Does your dog have diarrhea? Have you caught your pet scratching or rubbing its hindquarters? Are there visible red marks or sores on your dog’s skin?

If your dog shows any of these symptoms, he or she might have worms. As with any other health problem, you should pay attention to anything that is out of the ordinary.

All these signs are very noticeable, but keep in mind that sometimes there would be no explicit signs and symptoms.

Before you freak out, this isn’t unusual or uncommon. It happens with most dogs one or more times during their lifetime. Even if your dog isn’t infected, like most pets, dogs should be dewormed once a year as a precaution.

Some of the ways in which worms spread are through fleas, from contaminated foods, contact with feces or even from a pregnant dog to her unborn pups. The different worms and parasites have different effects on your pet’s health. The more severe and extensive an infestation becomes the more adverse its effects. Some parasitic infections like heartworms could even be fatal.

Even less serious infections can still make your pet very uncomfortable. Other important reasons to treat and prevent worms in your dog is to prevent the parasites from infecting other pets as well as humans who interact with your pet.

How to Deworm Your Dog?

Usually, your vet will treat your pet for these parasites at their annual checkup. However, there are other options available. As worms are the most common health problems in dogs, it’s lucky that there are many ways to deworm your pet at home too.

You will be able to find over the counter dewormers at pet stores, department stores, and veterinary stores. Nowadays they can also be bought online.

With so many products available it is difficult to choose one to buy for your dog. It can be tempting to grab the first and cheapest product that you see. However, not all products are the same, and not all of those available are effective.

What Do You Need to Think About When Buying a Dewormer for Your Dog?

Choosing a dewormer isn’t as simple as we might want it to be. There are a lot of things to consider when you buy a deworming treatment. Let’s look at the essential criteria by which a product should be measured.

1. Safety

Whenever you buy something for your pet it’s your responsibility to make sure that it is safe to use. Make sure that the brand or source of the treatment can be trusted. When you browse for products, check whether they have been approved by the appropriate government bodies.

Part of this is making sure that you give your pet the correct dose of the medication. You should also buy a treatment that isn’t ideal for your pet’s species and breed. Dewormer for other pets aren’t suitable for dogs. In addition to this, see whether the medicine is for large, medium or small breed dogs.

The treatment should not make them sick and should not have too many side effects.

2. Effectiveness

Besides safety, the second most important aspect to think about is whether it will work. Not all products are of the same quality.You should do some research beforehand to find out whether the remedy will get rid of the pests. A handy way to gauge its effectiveness is to look at other reviews. The closer the stories are related to yours and the more positive experiences other customers had, the better.

3. What Parasites Does It Target?

The effectiveness of the treatment is impacted by the specific parasites that it targets. Your pet might only be infected with one type of worm or with more than one. They aren’t all killed by the same remedy.

Some of the most common worms are hookworms, roundworms, tapeworms, and whipworms. 

Parasites on a pet’s skin are more straightforward to identify than intestinal worms. With severe infestations, worms can sometimes be visible in their feces. You might want to take your pet to the vet to find out what parasites they are infected with.

4. What Form Is the Medication in?

Many of the dewormers that are available are in the form of chewable tablets. These tablets are usually flavored so that your dog will enjoy eating them.

This is probably the easiest way to administer the treatment. Other forms like pastes etc. can be tricky to use with pets that aren’t accustomed to them.

I will use all these features to review 5 of the top dewormers that are available on the market.
