Shivering in dogs, particularly in small breeds like Chihuahuas, can stem from various causes. It might be due to feeling cold, experiencing anxiety, excitement, or even pain. Given that your dog is shivering along with an elevated heartbeat and bad breath, it's crucial to consider these symptoms collectively.

The fact that the shivering occurs episodically suggests it might be triggered by specific situations or stimuli. Try to observe if there's a pattern or specific trigger, such as loud noises, new environments, or interactions with other animals or people.

At home, you can help by ensuring your dog is warm and comfortable, especially if the weather is chilly. Providing a cozy blanket or a warm spot to rest can be quite helpful. If anxiety seems to be a trigger, creating a calm environment and offering gentle reassurance can be beneficial.

The bad breath might indicate dental issues, which are common in older dogs and can sometimes cause discomfort or pain, potentially leading to shivering. Regular dental care, such as brushing your dog's teeth or providing dental chews, can help manage this.

While these symptoms are not immediately alarming, it's important to keep an eye on your dog's condition. If the shivering becomes more frequent, or if you notice any additional symptoms like changes in appetite, lethargy, or a persistently elevated heart rate, it would be wise to consult a veterinarian to rule out any underlying health issues.

If you have any further questions, please feel free to ask. Thank you.
