It is best to deworm dogs before vaccination

Generally speaking, we believe that puppies can receive deworming starting from the fourth week. As long as the dosage is scientific, there will be no problems. Dogs that have been dewormed Not only will your appetite be better, but your body will develop more normally because the nutrients you eat will not be invaded by parasites. (It should be noted that if the mother dog is not dewormed before mating, or the food is not clean, the puppies will be more likely to carry parasites.)

Dogs are susceptible to infection Parasites

The vaccine injection time is in the sixth week. A milder vaccine can be administered earlier, but in terms of time, it should still be scheduled after deworming. Nowadays, due to the improvement of family dog-raising environment and breeding level, the proportion of deaths caused by infectious diseases in puppies has dropped significantly, but the proportion of deaths caused by diarrhea has increased significantly. Diarrhea will cause puppies to stop eating or drinking, and their blood sugar will drop, leading to death. Parasites are an important cause of diarrhea.

Deworming can ensure the smooth vaccination of dogs

The function of vaccination is to prevent infectious or spontaneous infectious diseases, but its important prerequisite is to ensure that Provided the puppy is in good health. Whether there are parasites in the stomach is an important reference standard for the health of puppies. Therefore, if you have not experienced deworming, you cannot guarantee that your puppy will be absolutely healthy. In this case, because the vaccine is a biological agent of a weak strain, it will cause the puppy's immunity to be low within a week. If there are parasites in the puppy's body, it may be infected by the parasite and cause disease due to its weak body.
So the conclusion drawn from the above is: deworming comes before vaccine
