Generally speaking, dogs must be dewormed externally once a month, while internally dewormed internally once every three months. Dogs must carry out external deworming when they reach the next month's age. At this time, they are more sensitive and are very prone to parasites. In addition to the body, the possibility of infection with parasites is smaller, so it does not need to be as frequent as external deworming.

The frequency of deworming dogs

Generally speaking, when dogs are older than the next month, they must complete external deworming once every month, while internal deworming is recommended once every three months. Dogs are in a more sensitive link when they are one month old and are more likely to be infected with parasites. Therefore, they must be dewormed when they reach one month of age.

The chances of infection with parasites outside the dog's body are higher because the skin on its face is exposed to the air at all times. The chance of infection with parasites in the body is much smaller. As long as the breeder ensures the reliability of the food and environmental sanitation, dogs will not be easily infected with parasites in the body, so don’t be as frequent as external deworming.

External deworming is generally used to use a burette to drip the deworming medicine on the skin of the dog. In order to better use the medicine power, it is recommended that you not take a bath within the next three days. If injections are carried out, it is not recommended to take a bath for the next week to prevent infection at the pinhole.
