If you’ve ever searched “why is my dog shaking?”—you’re not alone. Trembling, shivering, or shaking in dogs is a common concern among Arizona pet owners, especially given the region’s unique environmental risks.
While some causes of shaking are harmless—like excitement or a sudden chill—others may signal a medical emergency. From heat stress to desert wildlife encounters, knowing when to call your vet can make all the difference.
At 1st Pet Veterinary Centers, we see thousands of dogs each year—and many for this exact concern. Let’s walk through seven common reasons dogs shake, when to be concerned, and how we can help.
7 Common Reasons Why Arizona Dogs Shake
1. Pain or Injury
Pain is one of the most frequent causes of shaking. Dogs may tremble due to muscle sprains, broken bones, or internal injuries—even if the injury isn’t immediately visible. If your dog was recently active or in an accident (even minor), shaking could be their way of expressing discomfort.
2. Anxiety or Fear
Fireworks, thunderstorms, car rides, or vet visits can trigger intense fear responses. In anxious dogs, shaking is often accompanied by hiding, whining, or restlessness.
3. Heat Stress or Dehydration
Arizona’s heat can take a serious toll. If your dog has been active in the sun, shaking may signal overheating or dehydration—both urgent issues in desert climates.
4. Rattlesnake Bite
This is one of the most serious causes of sudden shaking in Arizona. A rattlesnake bite often results in trembling, swelling, weakness, or collapse. Immediate emergency care is critical—antivenom may be required.
5. Scorpion Bite
Though often less severe than snake bites, a scorpion sting can cause localized pain, twitching, trembling, or paw shaking. Small dogs are more vulnerable and may react more intensely.
6. Nausea or Upset Stomach
Dogs may shake before vomiting or while experiencing nausea. This can be caused by food intolerance, toxins, or illness.
7. Neurological Issues
In some cases, shaking stems from seizures, tremors, or age-related neurological degeneration. These conditions require veterinary diagnosis and ongoing management.
When to Call the Vet
Not all shaking is an emergency—but in Arizona, you can’t afford to take chances. If your dog is shaking and showing any of the following symptoms, call a veterinarian immediately:
- Swelling, bleeding, or visible bite marks
- Difficulty walking or disorientation
- Shaking with vomiting, diarrhea, or collapse
- Exposure to heat, snakes, or scorpions
Even mild cases of shaking—especially in smaller dogs or seniors—should be evaluated if they persist. When in doubt, it’s always safest to err on the side of caution.

Final Thoughts: Know What’s Normal—And What’s Not
Some shaking is normal. Dogs may tremble when excited, cold, or nervous. But in Arizona—where desert dangers are real—it’s important to recognize when that shaking could be a symptom of something more serious.
- Don’t ignore sudden or intense trembling
- Stay alert to desert-specific risks, like rattlesnakes or scorpions
- Heat stress and dehydration can become emergencies quickly
- And always—when in doubt, call your vet
