Vaccines are a routine part of pet care. Most cats and dogs get them at least once a year and it’s good to have a sense of what potential side effects may be.

If your pet is going to experience adverse effects from vaccines it will most likely happen within hours of the appointment. If any of the following listed side effects persist beyond 24 hours please call us at 510-549-1252.

  • Swelling at the vaccination site
  • Mild fever
  • Inappetance and lethargy
  • Sneezing or mild coughing (with nasal vaccines)

In rare instances, allergic reactions may occur which can be life-threatening.  These will also happen soon after the vaccines are given. If you see any of the following get in touch with us at the clinic (or P.E.T.S. if we are closed at 510-548-6684).

  • Persistant vomiting or diarrhea
  • Itchy, bumpy skin (“hives”)
  • Swelling around the muzzle, face, neck and eyes
  • Severe coughing or difficulty breathing
  • Collapse

If you are aware of your pet having had reactions to vaccines in the past, let your veterinarian know about it. It’s always better to be safe than sorry!
