The whole process of deworming emphasizes removing the harmful parasites from the body of the puppy. After the vet confirms the worms, then the dosage would start for the puppy’s deworming process. The puppies may have tapeworms, roundworms, hookworms, and whipworms. Basically, these worms live inside the intestine (wall) of the puppies.

The vet would recommend the owner to give the required dosage to the puppies according to the type of worms present inside the puppy’s body. Anemia can be a repercussion of worm infection in puppies. The worms such as hookworms will soak (or drain) the blood from the intestine’s wall of the puppy. This will call for more blood requirements for the puppies.

The worms will not hatch at the same time and therefore, the puppy has to take a few dosages of deworming. The first stage (of deworming) would act effectively in killing and clearing out the present worms in the intestine’s wall. In the second round, all the newly hatched worms would be paralyzed or dissolved by the dosage.

The dosage of deworming is mainly taken in the form of tablets or shots (through injection).


Some of the symptoms of worm infestation in puppies are weakness, inflammation (bloating), weight loss, and food craving. Some puppies are asymptomatic and would not show any symptoms of worm infestation. The medications for worms infestation come with a broader scope and works effectively against many kinds of worms.

The puppies are supposed to go through the deworming medications for three months. The vet may ask for more dosages of deworming medicines if the puppy is infected with the worms after 3 months.
