Buying Guide for Best Dog Dewormer

Even if your pet looks healthy, there are good chances that it may suffer from worming. So it is important to know if your pet is suffering from worms. As we already mentioned the top worming medications for dogs in this section, we provide a clear view of dewormers and how to choose them.

What is Deworming for Dogs?

Deworming is a process of eliminating intestinal worms in dogs. These worms are mostly tapeworms, hookworms, roundworms, heartworms, and whipworms. It is generally done by feeding the dogs a chewable tablet or a liquid directly containing anthelmintic drugs, which further eliminates all the worms and parasites in their bodies.

How do Dogs Get Worms?

Dogs, being restless and playful animals, love running around in places that may be present with contaminated soil and mud. This contaminated soil and mud is the birthplace of these worms, their eggs, larvae, and worms themselves. Dogs ingest these eggs and worms, and they slowly build up in their stomach and move to their intestines, causing them pain, and prolonged infestation of worms could lead to serious body infections.

What are the Signs of Worms in Dogs?

Dogs are expressive animals, and they offer signs of distress through changes in their eating habits, energy levels, and excreta. Common signs of worm infestation in dogs include changes in their appetite, usually decreased eating. They may be lethargic and face diarrhea which may contain blood and worms. Presence of worms in their vomit and a low and sad demeanor caused due to irritability in their stomach.

How Does a Dog Dewormer Work?

Dewormers are highly effective because of their active ingredients being pyrantel pamoate and praziquantel. These not only kill the worms but also break them apart. Tablets or the liquid get digested in their bodies, work from their stomach, and kill the worms present. All worms then let out by the dogs in their excreta.

When to Deworm a Puppy?

Puppies are extremely prone to getting worms because of their playfulness and the lack of training to avoid consuming contaminated material that may contain worms. Therefore, puppies that reach 2 weeks or older should be dewormed. If they don’t have them, a deworming pill will also prevent their growth in their body by killing eggs and larvae.

Are Dog Worms Contagious?

Worms in dogs are contagious, and they can pass one person or dog to the other. The worms are present in their intestines. Their eggs, larvae, and small growing worms are passed out through their excreta. If you make your dog excrete in a harvesting garden or farm, these larvae and eggs get passed on to the soil and the product that children and other dogs can accidentally consume, in turn causing worms in their bodies well.
