While parvovirus vaccines are generally safe and effective, some dogs may experience mild side effects, such as:
* Lethargy: A temporary decrease in energy levels.
* Loss of appetite: Reduced interest in food.
* Swelling or soreness at the injection site: This is common with any vaccine.
* Fever: A slight increase in body temperature.
These side effects are typically mild and resolve on their own within a day or two.
If you notice any of the following, contact your vet immediately:
* Severe lethargy or weakness: Your dog is unable to stand or walk.
* Vomiting or diarrhea: Especially if it's bloody or persistent.
* Seizures: Any unusual neurological signs.
* Difficulty breathing: Rapid or labored breathing.
