* Shaking: Shaking in dogs can be a sign of a wide range of issues, including pain, fever, fear, hypothermia, and neurological problems.
* Not eating treats: Loss of appetite is a major red flag, especially when coupled with other symptoms. It suggests an underlying illness.
* Cold ears: This could indicate hypothermia (low body temperature), which is a serious medical condition.
What to do immediately:
1. Contact your veterinarian or an emergency animal clinic immediately. Explain the symptoms and get guidance on what to do next. They might be able to provide initial advice over the phone.
2. Keep your dog warm. Wrap him in a blanket or towel to help raise his body temperature. If you have a heating pad, use it on a low setting with a layer of towels between the pad and your dog.
3. Don't force your dog to eat or drink. This could be harmful if they have a serious medical issue.
4. Monitor your dog closely. Note any changes in behavior, breathing, or condition.
Possible underlying causes:
* Hypothermia: This is a serious condition that needs immediate medical attention.
* Infection: Infections can cause fever, shivering, and loss of appetite.
* Pain: Your dog may be shaking due to pain from an injury or illness.
* Poisoning: Some poisons can cause tremors and loss of appetite.
* Neurological issues: Certain neurological conditions can cause shaking and other symptoms.
Remember: It's better to err on the side of caution. Seek immediate veterinary care if your dog is exhibiting these symptoms to ensure they receive the proper treatment.
