Abdominal emergencies: bloat, blockages and blocked cats

These are the surgeries nobody plans for: the great dane with a twisting stomach, the labrador that ate a corn cob, the cat straining in the litter tray at midnight. The decisions come fast, the invoices come faster, and the difference between good and bad outcomes is usually measured in hours. This guide is best read before you need it.

GDV: the one where minutes count

Gastric dilatation volvulus, bloat with a twist, is the deep chested breed nightmare: the stomach fills with gas and rotates, sealing itself shut and choking its own blood supply. A dane, shepherd, weimaraner or any big dog retching without producing anything, with a swelling belly and sudden distress, is not a wait until morning situation; it is the fastest genuine emergency in this guide. Treated promptly, most dogs survive; every hour of delay moves the odds and the invoice the wrong way.

Blockages and blocked cats: the other two regulars

Swallowed objects, toys, corn cobs, socks, fruit pits, sit anywhere from harmless to intestine killing, and imaging decides which. Caught early, some are retrieved by endoscopy without a single cut, at a fraction of surgical cost. The blocked cat is its own emergency: a male cat straining and producing nothing is in danger within a day, and while unblocking is routine, the repeat offender eventually faces the PU surgery conversation.

Common questions

How do I tell bloat from an upset stomach?

The GDV signature is unproductive retching, trying hard, producing nothing, plus a tightening or swelling belly, restlessness and drooling in a large deep chested dog. Any of that combination is an immediate emergency trip, and ringing ahead lets the hospital set up before you arrive.

My dog swallowed something an hour ago. Wait and see?

Ring a vet now rather than watching: for many recent swallows, making the dog vomit safely within a couple of hours solves it for a consultation fee, and for dangerous objects, batteries, needles, string, waiting forfeits options. The wait and see approach belongs to the vet's plan, not the kitchen table.

Is preventive gastropexy worth it for my dane?

Tacking the stomach at desexing is cheap insurance in the highest risk breeds: it largely prevents the fatal twist. If you own a dane, a giant breed or a dog whose relative had GDV, it is a conversation worth having before, rather than after.
