It's understandable to be concerned when your normally energetic dog feels more tired after flea medication. Mild lethargy is a common reaction to flea treatments and usually resolves within 24-48 hours.
- Mild lethargy can be a normal side effect of flea medications.
- Watch for any new or severe symptoms.
- Monitor your dog, ensuring they're comfortable and hydrated.
Flea treatments sometimes contain ingredients that can make dogs feel a little more tired. This effect is usually temporary and should improve on its own. If your dog is eating, drinking, and behaving normally otherwise, there's likely no cause for alarm. If the lethargy persists beyond 48 hours or is accompanied by other symptoms, a vet check would be a good idea.
