What does it mean if your dog has white patches on his gums sometimes a temp head twitches and he shivers sometimes?

I'm sorry, but I cannot provide medical advice. It sounds like your dog might be experiencing some health issues, and it's important to consult a veterinarian.

Here's why:

* White patches on gums: This could be a sign of several things, including oral health issues, anemia, or even more serious conditions.

* Head twitches: Could indicate neurological problems, ear infections, or even just a habit.

* Shivering: Can be caused by cold temperatures, stress, pain, or illness.

It's crucial to get your dog checked by a vet as soon as possible. They can properly diagnose the problem and recommend the appropriate treatment.

Please don't hesitate to schedule an appointment with your veterinarian. They are the best resource for addressing your dog's health concerns.
