SHe chewed on a cigarette butt earlier
Chewing on a cigarette butt can be quite dangerous for dogs, especially puppies, due to the nicotine and other harmful substances present in cigarettes. The symptoms are concerning and could be related to nicotine poisoning.
Given that your puppy is showing signs of lethargy and loss of appetite, it's crucial to seek immediate veterinary attention. Nicotine poisoning can progress quickly and can be life-threatening if not treated promptly.
In the meantime, avoid giving her any food or medications without consulting a veterinarian first.
Please take her to the nearest veterinary clinic or emergency animal hospital as soon as possible for a thorough examination and appropriate treatment.
