Dog Difficulty Breathing and Shaking: What to Know

6 min read

When a dog has trouble breathing and is also shaking or trembling, the combination can indicate several different conditions, some of which may require urgent veterinary attention.

Quick Answer

Difficulty breathing together with shaking or trembling in dogs can sometimes be associated with pain, fever, anxiety, toxin exposure, neurological issues, or low blood sugar. Because several of these causes can become serious quickly, prompt veterinary evaluation is generally advised.

Why Breathing Difficulty and Shaking May Occur Together

Shaking and trembling in dogs are non-specific signs that can accompany many different conditions. When paired with difficulty breathing, the two signs together narrow the list of possible explanations but still span a range of causes, from treatable infections to conditions that require immediate intervention. The key is to observe the full picture and seek professional assessment.

Possible Causes to Be Aware Of

Several conditions are sometimes associated with both breathing difficulty and shaking in dogs:

  • Pain: Dogs in significant pain may tremble or shake and may also breathe rapidly or shallowly. Pain from conditions such as pancreatitis, gastrointestinal obstruction, or orthopedic injury can produce this combination.
  • Fever: A high body temperature can cause shivering or shaking and may also increase respiratory rate as the body attempts to regulate its temperature. Infections, immune-mediated conditions, and certain inflammatory diseases can produce fever.
  • Anxiety or fear: Severe anxiety, panic, or a phobic response (such as to thunderstorms or fireworks) can cause rapid breathing, panting, and visible trembling. However, because serious medical conditions can produce similar signs, anxiety should only be considered after medical causes have been ruled out by a veterinarian.
  • Toxin exposure: Ingestion of certain toxic substances, including chocolate, xylitol, rodenticides, or certain plants, can cause neurological and respiratory symptoms that may include trembling and labored breathing. This is a time-sensitive situation that benefits from rapid veterinary intervention.
  • Neurological issues: Conditions affecting the brain or nervous system, such as seizures or vestibular disease, may cause trembling, changes in breathing pattern, and disorientation.
  • Low blood sugar (hypoglycemia): A drop in blood glucose levels can cause shaking, weakness, and in some cases altered breathing. This is more common in small-breed puppies, dogs with diabetes receiving insulin, or dogs that have not eaten for an extended period.

A veterinarian can evaluate your dog's vital signs, run diagnostic tests, and determine which of these or other causes may be responsible.

What to Monitor at Home

While preparing for a veterinary visit, the following observations can be valuable:

  • Type of shaking: Note whether the trembling is continuous or intermittent, whether it affects the whole body or specific limbs, and whether it worsens with movement or when the dog is at rest.
  • Breathing details: Count breaths per minute at rest and observe whether the breathing is shallow, deep, noisy, or accompanied by coughing or wheezing.
  • Context: Recall whether the signs began after a specific event, such as possible ingestion of a foreign substance, exposure to a stressful situation, or a change in environment.
  • Additional signs: Look for vomiting, diarrhea, drooling, pale or discolored gums, confusion, collapse, or any signs of injury.
  • Timeline: Record when each sign was first noticed and whether either sign has progressed or changed since onset.

This information can assist the veterinary team in prioritizing diagnostic steps.

When to Contact a Veterinarian

The combination of breathing difficulty and shaking should generally be evaluated by a veterinarian promptly. You should contact an emergency veterinary service without delay if you observe:

  • Gums that are pale, blue, white, or very dark red
  • Collapse, inability to stand, or severe disorientation
  • Active seizure activity lasting more than a few minutes or repeated seizures
  • Known or suspected ingestion of a toxic substance
  • Breathing that is severely labored, with visible effort from the chest or abdomen
  • Extreme lethargy or unresponsiveness

Even in the absence of these emergency indicators, a veterinary visit the same day is appropriate when a dog shows both respiratory changes and trembling. Some causes, such as toxin exposure or severe infection, benefit significantly from early treatment.

Frequently Asked Questions

Can anxiety cause my dog to shake and breathe heavily?

Anxiety can produce trembling, rapid breathing, and panting in dogs. However, because many serious medical conditions can cause the same signs, a veterinarian should evaluate the dog before assuming anxiety is the cause. Ruling out medical issues first ensures that a potentially dangerous condition is not overlooked.

Is shaking always a sign of something serious when combined with breathing difficulty?

Not necessarily. Mild trembling with slight changes in breathing can sometimes occur with minor issues. However, because it is difficult to distinguish between mild and serious causes at home, veterinary evaluation is the safest course of action whenever both signs are present.

What should I do if I think my dog may have eaten something toxic?

If you suspect toxin exposure and your dog is showing signs such as shaking and breathing difficulty, contact a veterinarian or a pet poison helpline immediately. Do not attempt to induce vomiting or administer any home remedy unless directed to do so by a veterinary professional, as some substances can cause additional harm if vomited.
