Dog Shaking Like Cold — Why It Happens
Dogs may shake as if cold due to anxiety, pain, internal illness, low blood sugar, or toxins. While mild trembling can be harmless or short-lived, persistent or intense shaking warrants closer attention.
Common Causes of Dog Shaking Like Cold
Pain or Discomfort
Dogs often shake in response to pain—whether it’s from arthritis, injury, or an internal issue.
Shaking from pain may be accompanied by restlessness, crying, or guarding a specific area.
Look for signs like limping, reluctance to move, or changes in posture.
Pain relief and prompt diagnosis can help your dog feel more comfortable quickly.
Fear, Stress, or Anxiety
Dogs may shake when they feel nervous, such as during thunderstorms, car rides, or separation from their owner.
This shaking is not from cold but from adrenaline and emotional stress.
They may also pace, pant, or try to hide.
Behavioral support, calming tools, and anti-anxiety training can reduce this response.

Low Blood Sugar (Hypoglycemia)
Especially common in small breeds and puppies, low blood sugar can cause shivering, weakness, and even collapse.
Dogs may act confused, seem wobbly, or lose consciousness if not treated.
Feeding small frequent meals and having glucose on hand can help prevent episodes.
Severe or recurring cases should be evaluated by a vet.
Toxin Ingestion
Some toxins like chocolate, xylitol, or pesticides cause shaking that resembles being cold.
Dogs may tremble violently, become agitated, or vomit.
Symptoms can escalate quickly depending on the substance and amount ingested.
Call your vet or pet poison control immediately if you suspect poisoning.
Fever or Illness
When a dog has a fever, their body may shake as it tries to regulate temperature—similar to how humans experience chills.
Infections, inflammation, or immune responses can all cause this.
You may also notice lethargy, appetite changes, or hot ears and paws.
A vet checkup can help identify the root cause and offer treatment.
What to Do If Your Dog Is Shaking Like Cold
Observe when and how the shaking occurs—is it after exercise, during rest, or in specific environments?
Check your dog’s temperature (normal range is around 101–102.5°F) and assess for other symptoms.
Create a calm, warm space for them to rest and avoid unnecessary stimulation.
Avoid giving any medications without veterinary approval.
If shaking continues or is paired with other symptoms, call your vet.
When to Call or Visit Your Vet
Seek veterinary attention if your dog:
Shakes continuously or violently
Shows signs of pain or distress
Has vomiting, diarrhea, or a fever
Acts weak, confused, or lethargic
May have ingested a toxic substance
Prompt care can help resolve the cause and bring your dog relief sooner.
