Internal deworming is as important as external deworming for the health of our dogs. However, many owners are still unaware of the importance of antiparasitics. Owners who do not deworm their dogs leave their animals exposed to infestations that can lead to: malaise, illness, and even death in the worst case. It is essential to become aware that dogs must be dewormed internally and externally several times a year (depending on the risks of each territory).
Internal deworming is usually the great forgotten, that is why in this article we have decided to inform you about why it is necessary to internally deworm dogs.
Common internal parasites in dogs
The main objective of deworming treatments is to prevent and treat the appearance of parasites in our dogs. Double deworming is the most effective and recommended by veterinarians. This is because there are parasites that can lodge in the body of animals, seriously affecting their health if they are not treated.
Generally, the most common internal parasites in dogs are intestinal worms, lungworms, and heartworms. All this can cause serious damage to a host animal and, therefore, it is important to carry out an adequate deworming of your dogs. Therefore, do not hesitate to ask your veterinarian for a double deworming plan to take care of your pet internally and externally.
Deworming: intestinal parasites in dogs
Most internal parasites can keep their eggs alive in the environment for long periods. These parasites are contagious and a dog can become infected by licking or simply smelling this infected area. Mothers with these types of infections can also pass the parasites to their puppies. Unlike what happens with external antiparasites, which maintain their effect for weeks, internal ones eliminate only the parasites that are present at the moment, and eliminate the parasites through the digestive system. This explains why it is necessary to deworm our dog on a regular basis, especially puppies.
Symptoms of such infections are generally not very apparent in healthy animals. However, in the case of puppies or immunosuppressed animals, they will show symptoms of: diarrhea, weight loss or anemia. A veterinarian, by examining a stool sample under a microscope, can identify the type of worm and prescribe an appropriate dewormer.
Symptoms of lung parasites in dogs
Lungworms affect the respiratory system of dogs. These lungworms can affect a dog that ingests snails or slugs that are infected with the larvae of this parasite. From that point on, the dog may begin to show signs of coughing and difficulty exercising. The parasites can also be observed in the animal’s feces.
Filariasis in dogs
Filariasis in dogs is another of the parasitic diseases that we have already talked to you about at length previously on our blog, and it is also known as heartworm. The filaria is a worm that lives in the pulmonary arteries and, as the disease grows, it travels towards the heart, and can cause thromboembolism and pulmonary hypertension and / or vena cava syndrome.
This disease appears through symptoms of dyspnea (difficulty breathing) and heart murmurs, which can cause the possible death of any animal that suffers from it.
A filaria reaches dogs through a mosquito. When the dog is bitten, the parasites enter the body, where they undergo different maturations that end with their migration towards the pulmonary arteries and the right side of the heart. Female filariae release microfilariae into the bloodstream. If a mosquito bites an already infected dog, it can transmit the parasite by biting another dog.
Generally speaking, symptoms include: coughing, exercise intolerance and even syncope (loss of consciousness). Due to the location of these parasites, being so close to the heart, it can end in the death of the animal. Treatment also carries risks, as dead parasites can cause blockages in vital organs. The serious consequences of canine filariasis perfectly explain why we have to deworm our dogs internally regularly, since prevention is the best weapon against this type of health problem.
How to deworm a dog?
Prevention is the best option we can choose against internal parasites. Consulting a veterinarian will allow you to analyze your dog and his environment, ensuring that your dog receives the best protection he needs for his particular lifestyle. For external deworming, you can easily find products, such as the famous pipettes, certain sprays or necklaces. For internal deworming, you may have to ask your trusted veterinarian for treatment: there are pills that you can add to your dog’s food and that will help to expel the most common possible intestinal parasites. In more serious cases such as filariasis, the vet will prescribe the most appropriate medication to start a treatment.
Once the vet establishes the deworming treatment (of whatever type), it is important to follow it scrupulously to keep your dog free of parasites. The damage that parasites can cause is very severe, so deworming our dogs on a regular basis is something that we must incorporate into the regular care of their health.
