It’s not uncommon for puppies to experience lethargy and a decrease in appetite after vaccinations. While mild side effects are normal, continued symptoms should be monitored closely.
- Monitor your puppy's symptoms over the next 24–48 hours
- Ensure she stays hydrated—encourage water intake
- Consider a follow-up with the vet if no improvement is seen
Vaccinations can sometimes make puppies feel a little under the weather as their immune system is responding to the vaccine. Common side effects include tiredness and loss of appetite, which typically resolve in a day or two. However, if your puppy is extremely lethargic, not drinking water, or if her condition worsens, it’s important to consult your veterinarian for further advice.
