Why Would A Dog Dry Heave: Causes, Symptoms & What To Do

When a dog dry heaves, it means they are making the motions of vomiting without actually expelling anything from their stomach. What is dry heaving in dogs? It’s a concerning symptom that can point to a range of issues, from minor stomach upset to serious medical emergencies. This comprehensive guide will explore the common reasons behind this behavior, the signs to watch for, and how you should respond if your dog is experiencing it.

Deciphering Dog Retching and Gagging

Dry heaving is often described as dog retching or dog gagging. While these terms are sometimes used interchangeably, there’s a subtle difference. Retching is the forceful, involuntary spasm of the abdominal muscles that mimics vomiting. Gagging is a sound or sensation of choking or difficulty breathing. In the context of dry heaving, the dog is experiencing retching, which can sometimes be accompanied by gagging sounds. It’s important to differentiate this from actual dog vomiting, where contents are expelled.

Common Culprits Behind Dog Nausea and Dry Heaving

Several factors can lead to a dog dry heaving. Some are relatively minor, while others require immediate veterinary attention.

Canine Indigestion and Upset Stomach

Just like humans, dogs can suffer from indigestion. This can be caused by eating too quickly, consuming something that doesn’t agree with them, or a sudden change in diet. When the stomach is irritated, it can lead to spasms and the feeling of nausea, prompting the dog to try and vomit.

Eating Too Fast: Some dogs gulp their food, swallowing air along with their kibble. This can lead to stomach distension and discomfort, resulting in dry heaving.
Dietary Indiscretion: Eating garbage, spoiled food, or even non-food items can upset a dog’s digestive system.
Sudden Diet Changes: Introducing a new food too quickly can cause digestive upset, leading to nausea and retching.

Gastric Dilatation-Volvulus (GDV) or Bloating

This is a life-threatening condition, especially in deep-chested breeds like Great Danes, German Shepherds, and Standard Poodles. GDV occurs when the stomach fills with gas, fluid, or food, and then twists (volvulus) around on itself. This twists cuts off blood supply to the stomach and can rapidly become fatal.

Key signs of GDV include:

Restlessness and pacing
Distended abdomen (bloating)
Unproductive retching (dry heaving)
Excessive drooling
Weakness and collapse

If you suspect your dog has GDV, it’s a CANINE EMERGENCY. Seek veterinary care immediately.

Esophageal Issues

Problems with the esophagus, the tube that carries food from the mouth to the stomach, can also cause dry heaving.

Esophagitis: Inflammation of the esophagus can make swallowing painful and trigger retching. This can be caused by vomiting, acid reflux, or ingesting irritating substances.
Megaesophagus: In this condition, the esophagus is enlarged and doesn’t move food down to the stomach properly. Food can sit in the esophagus, leading to regurgitation and sometimes retching.

Foreign Body Obstruction

If your dog swallows something they shouldn’t have, it can get lodged in their digestive tract. This dog foreign body can cause irritation and blockages, leading to various symptoms, including dry heaving.

Symptoms of a foreign body: Vomiting (often after eating or drinking), lethargy, abdominal pain, loss of appetite, and dry heaving.
Common culprits: Toys, bones, socks, fabric, and even rocks.

If you suspect your dog has swallowed something, contact your veterinarian.

Pancreatitis

Dog pancreatitis is an inflammation of the pancreas. This organ produces enzymes that help with digestion. When it becomes inflamed, these enzymes can leak out and damage the pancreas itself and surrounding tissues.

Causes: Often idiopathic (unknown), but can be triggered by fatty meals, certain medications, or underlying health conditions.
Symptoms: Severe abdominal pain, vomiting, diarrhea, lethargy, loss of appetite, and often, dry heaving due to nausea.

Kennel Cough and Respiratory Issues

While primarily a respiratory illness, dog kennel cough (infectious tracheobronchitis) can sometimes manifest with gagging and dry heaving. The characteristic symptom is a harsh, honking cough, but severe coughing fits can trigger the gag reflex.

Other causes of respiratory distress:
- Collapsed trachea
- Heart disease (leading to fluid in the lungs)
- Pneumonia

If breathing difficulties accompany dry heaving, it’s a serious concern.

Other Potential Causes

Parasites: Severe intestinal parasite infestations can cause nausea and vomiting.
Kidney or Liver Disease: These can lead to a buildup of toxins in the body, causing generalized illness, including nausea and retching.
Motion Sickness: Some dogs experience nausea during car rides, which can result in dry heaving.
Stress or Anxiety: In some cases, extreme stress or anxiety can manifest physically, leading to stomach upset and retching.

Recognizing the Signs: What to Look For

When your dog is dry heaving, it’s not just the act of retching itself. Several other symptoms can accompany it, providing clues to the underlying cause.

Visual Cues and Sounds

Repeated Gagging or Retching: The most obvious sign is the repeated attempt to vomit without bringing anything up.
Abdominal Contractions: You might see the dog’s belly muscles contracting forcefully during the retching attempts.
Drooling: Excessive salivation is common, as the dog’s body is preparing to vomit.
Restlessness: The dog may seem uncomfortable, pacing, or shifting positions.
Whining or Vocalizing: Some dogs will whine or cry due to discomfort or pain.
Lethargy: The dog may appear unusually tired or depressed.
Loss of Appetite: A dog that is feeling unwell will likely refuse food or treats.

Other Symptoms to Note

Distended Abdomen: A swollen or firm belly is a critical sign, particularly if associated with dry heaving, as it can indicate GDV.
Pain: Your dog may react if you touch their abdomen or show other signs of pain, such as guarding their belly.
Diarrhea or Constipation: Changes in bowel movements can accompany digestive upset.
Changes in Water Intake: Some dogs may drink excessively, while others may refuse water.
Difficulty Breathing: This is a serious sign that requires immediate veterinary attention.

What to Do When Your Dog Dry Heaves

Your first step should always be to remain calm and assess the situation. Prompt action can make a significant difference, especially in emergency cases.

Immediate Actions

Observe Your Dog Closely: Note the frequency and duration of the dry heaving, as well as any other symptoms you observe. Is your dog acting normally otherwise? Are they distressed?
Check for Bloating: Gently feel your dog’s abdomen. Is it hard or distended? If you suspect bloating, especially in a deep-chested breed, contact your veterinarian immediately.
Prevent Further Eating or Drinking: If your dog is actively retching, it’s best to withhold food and water temporarily to prevent aspiration (inhaling vomit into the lungs) or further irritation. However, if the dry heaving is infrequent and your dog is otherwise bright, this may not be necessary.

When to Seek Veterinary Care

Contact your veterinarian immediately if:

Your dog is lethargic, weak, or collapsed.
Their abdomen is distended or appears painful.
They are having difficulty breathing.
The dry heaving is frequent, persistent, or worsening.
You suspect they have ingested a foreign object.
Your dog has a known pre-existing condition, like heart disease or kidney issues.
The dry heaving is accompanied by severe vomiting or diarrhea.

Veterinary Diagnosis and Treatment

When you bring your dog to the vet, they will perform a thorough physical examination. They may also recommend diagnostic tests to determine the cause of the dry heaving:

Bloodwork: To check for infection, inflammation, organ function, and electrolyte imbalances.
X-rays: To visualize the stomach, intestines, and other internal organs for foreign bodies, obstructions, or signs of bloating.
Ultrasound: To get a more detailed view of abdominal organs and detect issues like pancreatitis.
Endoscopy: A procedure where a flexible camera is inserted into the esophagus and stomach to visualize the lining and retrieve foreign objects.

Treatment will depend entirely on the diagnosis:

For GDV: Emergency surgery is required.
For foreign bodies: Surgery may be necessary to remove the object.
For pancreatitis: Supportive care including IV fluids, pain management, and anti-nausea medications.
For indigestion: Dietary adjustments, antacids, or probiotic supplements.
For respiratory issues: Medications to treat the underlying cause, such as antibiotics for kennel cough.

Preventing Dry Heaving in Dogs

While not all instances of dry heaving can be prevented, certain measures can reduce the risk.

Dietary Management

Feed High-Quality Food: Choose a diet that is appropriate for your dog’s age, breed, and activity level.
Avoid Sudden Diet Changes: Transition to new foods gradually over 7-10 days.
Don’t Overfeed: Feed your dog the appropriate amount of food to maintain a healthy weight.
Consider Slow Feeders: If your dog eats too quickly, use a slow feeder bowl to encourage more mindful eating.
Limit Fatty Treats: High-fat foods can be a trigger for digestive upset and pancreatitis.

Environmental and Behavioral Factors

Supervise Your Dog: Prevent your dog from eating garbage, unknown plants, or other potentially harmful items.
Secure Your Trash: Ensure your garbage cans are well-sealed to prevent access.
Manage Stress: Minimize stressors in your dog’s environment, especially for travel. Consider anti-anxiety aids if motion sickness is an issue.
Regular Exercise: Keep your dog physically active, but avoid vigorous exercise immediately after eating, especially for breeds prone to GDV.

Regular Veterinary Check-ups

Preventative Care: Regular check-ups allow your vet to catch potential health issues early, before they become serious.
Deworming: Keeping your dog on a regular deworming schedule can prevent severe parasite infestations.
Vaccinations: Staying up-to-date on vaccinations can protect your dog from infectious diseases like kennel cough.

Frequently Asked Questions (FAQ)

Q1: Can a dog dry heave from stress?
A: Yes, in some cases, extreme stress or anxiety can cause a dog to experience physical symptoms like nausea and dry heaving.

Q2: My dog dry heaved once, should I worry?
A: A single episode of dry heaving without other symptoms might not be a cause for major concern, especially if your dog then eats or drinks normally. However, if it happens again, or if your dog shows any other signs of illness, it’s best to consult your veterinarian.

Q3: How long does it take for a dog to recover from mild indigestion?
A: For mild indigestion, a dog might recover within a few hours to a day once the offending food or overeating is out of their system. However, if symptoms persist or worsen, veterinary attention is crucial.

Q4: Can my dog drink water after dry heaving?
A: If the dry heaving was a single, isolated event and your dog seems otherwise normal, you can offer a small amount of water. If they continue to retch, withhold water and seek veterinary advice.

Q5: What are the most common causes of dry heaving in puppies?
A: Puppies are prone to gastrointestinal upset due to their developing digestive systems. Common causes include eating too fast, dietary indiscretion, and intestinal parasites. Foreign body ingestion is also a risk as puppies explore the world with their mouths.

Conclusion

Dry heaving in dogs is a symptom that should never be ignored. While it can sometimes be a sign of mild indigestion, it can also indicate serious and life-threatening conditions like GDV or foreign body obstruction. By familiarizing yourself with the potential causes, recognizing the associated symptoms, and knowing when to seek veterinary care, you can best protect your canine companion’s health and well-being.
