Here's why:
* Lethargy and worms are serious symptoms. They could indicate a severe underlying health condition, like intestinal parasites, bacterial infection, or even a more complex illness.
* Self-treating can be dangerous. Giving your dog medication without professional guidance can be harmful and might mask the true cause of the problem.
Here's what you should do:
1. Contact your veterinarian right away. Describe the symptoms and any other unusual behavior your dog is exhibiting.
2. Follow their instructions carefully. They may advise you to bring your dog in for an immediate examination or recommend specific steps to take before your appointment.
3. Do not attempt to remove the worms yourself. This can cause pain and further complications.
Remember, your dog's health is paramount. Prompt veterinary attention is essential for a proper diagnosis and treatment plan.
