* Stress: Bathing can be stressful for some dogs, and being stressed right before a vaccination could make them more sensitive to the shot.
* Absorption: While bathing itself shouldn't directly interfere with the vaccine, the stress response and potential skin irritation could affect how the vaccine is absorbed.
* Open wounds: If your dog has any cuts or scrapes, bathing could irritate them and make them more susceptible to infection.
Here's what you can do:
* Bath beforehand: If your dog needs a bath, do it a few days before their vaccination appointment.
* Cleanliness: If your dog is particularly dirty, you can try to spot clean them before the appointment.
* Talk to your vet: If you're unsure, always consult with your veterinarian. They can advise you based on your dog's individual needs and health history.
Remember, the most important thing is to make sure your dog is as comfortable and relaxed as possible during the vaccination process.
