It's common for puppies to be a bit quieter than usual after receiving vaccines. This is usually a normal reaction as their immune system responds to the shots.
- Mild lethargy and decreased activity are typical post-vaccine reactions.
- Symptoms usually resolve within one to two days.
- If symptoms persist or worsen, consult a veterinarian.
After vaccinations, it's not uncommon for puppies to feel a little worn out as their body adjusts. This can mean being more tired or less playful than usual. Just like humans, some puppies may have mild side effects from vaccinations such as slight soreness at the injection site or lethargy. Observe your puppy, ensure he has a restful environment, and monitor any changes. If the calmness seems prolonged or there are troubling symptoms like vomiting or swelling, reach out to a vet for advice.
