Vaccine Reactions

Vaccine reactions are uncommon in dogs and rare in cats. Any pet may experience a reaction but some breeds of dogs can be predisposed to vaccine reactions. ;Breeds such as dachshunds, Cocker spaniels, poodles, Weimaraner, Scottish terrier, Shetland sheepdog, Great Dane, German shepherd, Golden retriever, Irish setter, Shih Tzu, Vizsla, Akita, and Old English sheepdog should always be monitored closely for any signs of a reaction after receiving vaccinations.


If your pet has a history of vaccine reactions please notify our staff and the doctor before vaccines are given. Precautions can be taken to reduce the risk of a reaction.

Symptoms of a reaction can include but are not limited to:

  • Muscle soreness, fever, reduced appetite, and lethargy which can last for a few days following vaccination.
  • Localized swelling, inflammation and pain at the injection site
  • Vomiting, diarrhea, facial swelling, itching, and hives
  • Vary rarely more serious complications such as anaphylaxis, autoimmune hemolytic anemia, vaccine site sarcoma, or death can occur.

Our vaccine clinic carries medication to address a reaction should one occur.
