There comes the point in the life of pets when they experience discomfort caused by parasites, ticks, fleas, and similar other worms. At times identifying fleas and ticks is easy for dog parents. But sometimes they may develop internal parasites which can be challenging to identify. The dogs keep growing parasites without your knowledge, and it becomes worrisome when the situation gets out of control. 

The parasites, once developed, are highly irritating to pets, and they may cause some health-related severe issues in dogs. The advent of science and modern medicines has made it easier for dog owners to treat, prevent, and control parasites than before.  

What are Parasites in Dogs? 

The disease control center has defined parasites as organisms that live inside or on the host organism. They feed on the host and get their food at the expense of the host’s health. They develop in dogs very quickly, and hence, you should take care of your dog to make sure that it doesn’t develop parasites. 

As a pet parent, you should be aware of two significant parasites usually found in dogs; external parasites and internal parasites. Internal parasites live inside the body of animals, such as hookworms, tapeworms, roundworms, and heartworms. On the other hand, external parasites are found on the host’s body and develop an infestation, such as ticks, fleas, etc. 

When your pet develops parasites, either internal or external anemia, secondary infections can occur in severe cases. You should consult your vet, and they will prescribe the required treatments and medications that will help you and your pet get rid of parasites. 

There are certain preventive medicines that can be administered regularly. For example, medicines like Heartgard Plus for dogs come as chewable tablets, and they are very effective in preventing and controlling the infection of certain worms in dogs. You can use and see results within just a few days of starting the course of the medicine.
