Here's why:
* Teeth chattering and loss of appetite can be signs of serious medical conditions. These could include dental problems, infections, poisoning, neurological issues, or even internal organ dysfunction.
* Delaying treatment can worsen the situation. It's crucial to get your dog seen by a veterinarian as soon as possible to determine the cause and get the appropriate treatment.
What to do next:
1. Contact your veterinarian immediately. Describe the symptoms and any other changes you've observed in your dog's behavior.
2. Follow your veterinarian's instructions. They may recommend an exam, bloodwork, or other tests to determine the cause of your dog's symptoms.
3. Do not attempt to treat your dog yourself. This could be dangerous and may delay proper diagnosis and treatment.
Remember, your veterinarian is the best resource for determining what's wrong with your dog. Don't hesitate to seek their expert advice.
