What should I do if my dog got an overdose of the Bordetella vaccine?

Yesterday, my dog received his routine Bordetella vaccine, but I was informed this morning that there might have been a mistake in the dosage and he got more than recommended. He seems a bit more lethargic than usual, though he’s still drinking water and eating a little. Should I be watching for specific symptoms of an overdose, or is there anything I should do to ensure he’s okay?

Answer

Your dog received an increased dosage of the Bordetella vaccine, and you're understandably concerned about his current lethargy and well-being. Monitoring him closely for any changes is important.

  • Monitor for unusual symptoms.
  • Keep him hydrated and comfortable.
  • Consult a vet if symptoms worsen.

Increased lethargy can sometimes occur after vaccinations, but it's good to keep an eye on other symptoms. It's reassuring that your dog is still eating and drinking; however, watch for vomiting, diarrhea, swelling, or difficulty breathing, which could indicate a more serious reaction. Ensuring he stays comfortable and quiet can help during this recovery phase. If symptoms worsen or you're worried, consulting with a veterinarian can provide peace of mind.

Book a consultation with a licensed vet at Dial A Vet for just $49 AUD if you're unsure or symptoms are getting worse.
