Home › Guides › Bloat (GDV) in Deerhounds: Signs and What to Do
Gastric dilatation-volvulus (GDV), commonly called bloat, is a life-threatening emergency in dogs. Scottish Deerhounds, with their deep, narrow chests and large internal cavity, are at elevated risk. Recognising the signs and understanding how to respond can mean the difference between life and death.
Why Deep-Chested Giant Breeds Are at Risk
GDV occurs when the stomach fills with gas and air (dilatation) and may twist on itself (volvulus). Once twisted, the stomach cannot empty, and its blood supply becomes compromised. Tissues begin to die within hours. Without surgical intervention, GDV is fatal.
Certain dog types are predisposed. Deep-chested, large-framed breeds—including Scottish Deerhounds, Irish Wolfhounds, Great Danes, and German Shepherds—have proportionally larger stomachs within a narrower chest cavity. This anatomy creates conditions where gas can accumulate and the stomach is more likely to rotate. Age also matters: GDV becomes more common as dogs get older, though it can occur at any age.
The exact cause of GDV is not fully understood. Potential triggers include eating too quickly, eating large meals, vigorous exercise immediately after eating, drinking excessive water, or even stress. However, GDV can occur without an obvious precipitating factor.
Early Signs of Bloat
Recognising early signs is critical. GDV progresses rapidly—survival depends on reaching a veterinary surgeon within hours of onset.
Initial signs include:
- Unproductive retching or attempting to vomit without bringing anything up
- Obvious distension (swelling) of the abdomen
- Restlessness or pacing; inability to settle or find a comfortable position
- Drooling or excessive salivation
- Shallow, rapid breathing
- Whining or signs of pain (sensitivity when touched on the belly)
As the condition progresses, the dog may collapse, become unresponsive, or go into shock. Do not wait for severe symptoms to develop before seeking help.
This Is an Emergency
If your Deerhound displays any of the above signs, treat it as a medical emergency. Do not wait, do not monitor, do not assume it will pass. GDV can become fatal within a matter of hours without intervention, as the twisted stomach cuts off its own blood supply and that of surrounding organs. Even with immediate surgery, outcomes are worse the longer treatment is delayed and tissue damage has progressed.
Immediate action:
- Stop all activity and feeding. Do not attempt to induce vomiting or give anything by mouth.
- Contact your veterinary surgeon immediately. Call ahead to warn them of a suspected GDV case so they can prepare.
- If your regular surgery is closed, locate the nearest emergency veterinary clinic or out-of-hours service. Most areas of the UK have out-of-hours emergency clinics staffed with surgeons capable of managing GDV.
- Transport your dog carefully to the clinic. Handle gently to avoid exacerbating shock.
Out-of-Hours Emergency Care
Most veterinary surgeries operate standard hours. For emergencies outside those hours, UK veterinary practices are required to have arrangements in place for out-of-hours emergency care. Your regular vet’s voicemail should provide a number for out-of-hours referral. Many areas have dedicated emergency hospitals (staffed with emergency and surgical specialists) operating 24/7.
Identify your local out-of-hours clinic before an emergency occurs. Add the number to your phone contacts and leave information at home with any dog-sitter or dog-walker you use.
What the Veterinary Surgeon Will Do
On arrival, the vet will perform an initial assessment and often take radiographs (X-rays) to confirm the diagnosis. If GDV is present, surgery is needed urgently.
Surgical treatment involves:
- Decompression: A needle or tube may be passed into the stomach to relieve gas pressure and allow some relief before surgery.
- Surgery: An incision is made into the abdomen, and the surgeon repositions the stomach to its normal location. The stomach wall and spleen are examined for tissue death (necrosis). Any necrotic tissue is removed.
- Gastropexy (optional): To reduce recurrence risk, the surgeon may tack the stomach to the abdominal wall, anchoring it in position. This does not prevent all future GDV cases but reduces recurrence significantly.
Post-operative care includes antibiotics, pain management, fluid therapy (often needed due to shock), and careful monitoring in a hospital setting for several days. Recovery can be lengthy, and some dogs experience complications.
Risk Reduction Habits
While no strategy eliminates GDV risk in at-risk breeds, several habits reduce likelihood:
Feeding practices:
- Divide daily food into two smaller meals rather than one large meal
- Allow time to pass after feeding before vigorous exercise or running
- Feed in a calm environment, free from competition or stress
- Some owners use elevated food bowls; evidence on their benefit is mixed, and they are not recommended in all cases—consult your vet
Hydration:
- Provide access to fresh water throughout the day
- Discourage gulping or excessive water intake immediately after meals
General care:
- Maintain calm temperament and avoid stressful situations before or after meals
- Monitor older dogs more closely for any abdominal signs
- Keep your veterinary surgeon informed of any family history of GDV in your dog’s bloodline
What is not evidence-based:
- Raised food bowls do not prevent GDV; some research suggests they may increase risk
- Specific commercial foods or dietary approaches have not been proven to prevent GDV
- Slowing feeding (using anti-gulp bowls) may help with stress-related eating but does not prevent GDV
Post-Surgery and Recurrence
Dogs that survive GDV surgery can live many years beyond the incident. However, recurrence risk is real—even with gastropexy, some dogs experience a second episode. Close observation for any return of symptoms is necessary.
If your Deerhound has experienced GDV, discuss with your vet any breed-specific breeding implications (if you intended to breed) and long-term management strategies.
Important Distinction
Bloating and mild gastric distension are common in dogs and usually resolve on their own. Occasional belching or slight belly distension after meals is normal. True GDV—with a tense, painful abdomen and unproductive retching—is a different phenomenon and requires immediate emergency care. When in doubt, err on the side of caution and contact a veterinary surgeon.
Key points
- Deep-chested giant breeds like Deerhounds are predisposed to GDV; it is fatal without emergency surgery
- Early signs include unproductive retching, abdominal distension, restlessness, drooling, and rapid breathing
- GDV is a medical emergency; contact a vet immediately if any signs appear
- Surgery is the only effective treatment; outcomes improve with rapid intervention
- Risk reduction through feeding habits (smaller meals, rest after feeding, calm environment) helps but does not eliminate risk
- Gastropexy during surgery reduces (but does not prevent) recurrence
