The dog can be vaccinated just after taking a bath, but it must be dried in time to prevent the dog from catching a cold. Before injecting the dog with the vaccine, you can check whether the dog is in good health. If everything is normal, the vaccine can be injected. It is best not to bathe your dog for a few days before and after injecting the vaccine, so as not to affect the efficacy of the drug and reduce the dog's immunity.
