Generally speaking, a three-day interval between deworming and vaccination is sufficient, but for dogs that have a strong vaccine reaction, it is recommended that deworming drugs be used until the vaccine reaction disappears. The reason why it needs to be done at intervals is because after vaccination, the dog's resistance will decrease. If the dog is dewormed again, it will increase the dog's burden, which will lead to vomiting, allergies, diarrhea and other abnormalities in the dog.

Things to note when deworming dogs:

1. First of all, deworming can only be carried out when the puppy is about 3 months old, because deworming drugs have a certain degree of Toxic, too young can easily cause damage to the body.

2. In addition, it should be noted that dogs with severe skin diseases or during the vaccination period cannot be dewormed.

3. Finally, take measures to keep the puppy warm during the deworming period, and do not take a bath to avoid catching a cold.
