Your veterinarian will provide some medicines that, even though, are harmful to pests; will keep your dog healthy. These medicines are also called ‘broad-spectrum’ due to their ability to kill numerous parasites together.  
    Worms are very common in dogs. Therefore, deworming for pets is necessary before the mother starts nursing or else the worm might pass onto the baby. The first dose of this process would kill any existing worm and the second dose would kill the ones that have newly hatched from their eggs. 
  1. Getting rid of heartworms: In case, your pet (dog) has heartworms in its blood, immediate treatment should be done. These tests are costlier ($1000) but highly effective than other deworming tests.  
    The pet is given a total of three shots within 2 months. While dying, these heartworms break into smaller pieces and block the blood flowing from the heart to the lungs. Thus, it requires the pet to stay calm during this period. With more activity, the heart might need to pump more blood which in turn can cause kill the animal.

How often should deworming for pets be done?

In general, pets should be dewormed every two weeks till they reach the age of twelve. Once they complete this course, they should be dewormed monthly till six months of age. However, there are several other guidelines proposed by different parasite councils regarding the process.

According to the Companion Animal Parasite Council (CAPC), deworming should be done every month depending on the duration of the activity of the drug used. This way the treatment becomes user-friendly and easy for owners to remember. 

On the other hand, the European Scientific Council Companion Animal Parasites (ESCCAP) provides a different approach. According to them, deworming for pets should be done four times a year. They believe that this process does not allow the increase of parasite levels in pets. 

Finally, the Canadian Parasite Expert Panel believes that this treatment should be done based on fecal examination results. For houses that are at a lower risk for parasites, exposure need not opt for deworming. In case, the fecal examination results are not well, one can perform this test once or twice a year. 

What are the common mistakes that people make while deworming?

Common mistakes people make while deworming

Owners can sometimes make mistakes regarding the process of deworming. Missing out steps can have adverse effects on the pet. Some of the common mistakes while deworming for pets are:

  • Forgetting that the second dose for deworming should be administered within 15 days of the first dose. In case one is careless about this factor, the first shot will become ineffective
  • The dose of the medicine is determined by the weight of the pet. Thus, using an anti-parasitic without realising the actual weight can lead to an underdose or overdose of your pet.
  • Owners might think that using anti-parasitics, eliminates all kinds of parasites present in the body of the pet. This is not the picture in many cases. Different processes are suggested by veterinarians to treat different parasites. Thus, it is a big misconception when people think that one parasitic is enough to kill all worms.
  • Owners often administer the medicine orally to their pets without ensuring that they have swallowed it. Thus, pets can easily spit out the medicine in their owner’s absence.

These worms can get highly infectious to people, especially children, pregnant women and diabetic patients.
