Here's why:
* Seriousness: The symptoms you described (vomiting, diarrhea, and shaking) could indicate a range of conditions, some of which are very serious and require urgent medical attention.
* Underlying Causes: These symptoms can be caused by things like:
* Food poisoning
* Parvovirus
* Pancreatitis
* Gastrointestinal blockages
* Infections
* Other medical conditions
* Risk of Worsening: Delaying treatment can lead to dehydration, malnutrition, and other complications.
What you should do:
1. Call your veterinarian immediately. Explain the symptoms and your dog's history.
2. Follow their instructions. They may advise you to bring your dog in for an exam or provide emergency care instructions over the phone.
Please remember, your dog's health is a priority. Don't hesitate to seek professional help.
