Your pet may be lethargic if they seem off or have decreased interest in their usual activities. You know your pet, so trust your instincts if something just seems off. If you suspect lethargy, it is important to consult with your vet since it may indicate a more serious medical condition. Instead of focusing on the cause of your pet's lethargy, pay close attention to their behavior, especially the progression of their lethargy over time.
- Discontinue anti-inflammatory and pain medicines, until your pet is eating regularly. Consult with your vet about the need to stop other oral medications.
- If possible with a home scale, weigh your pet daily and look for any weight loss.
