Colic

Colic in dogs refers to painful cramps in the abdominal cavity, which can range from harmless food intolerance to life-threatening gastric torsion (bloat). Unlike in horses, where the term is clearly defined, colic in dogs describes a symptom picture with very different causes.

When does colic in dogs become an emergency?

A dog with a distended, hard abdomen and unsuccessful retching behaviour, which indicates gastric torsion (bloat), needs to go to the vet within 30 minutes. Other emergency signs are pale mucous membranes, weak pulse and tendency to collapse.

In a six-month-old Labrador puppy, an owner observed after eating: The dog paced restlessly, arched its back and could not vomit despite retching movements. The abdomen felt drum-tight. Emergency surgery took place two hours later; the stomach had already twisted 180 degrees.

What causes trigger colic?

The range extends from trivial gas formation to surgical emergencies. Foreign bodies such as chestnuts or tennis balls mechanically block the intestine, while bacterial infections cause inflammatory paralysis of the gut.

In large dog breeds weighing over 30 kg, gastric torsion (bloat) occurs more frequently, especially after hastily gulping down large amounts of food. Stress increases the risk: A move, new family members or New Year’s Eve fireworks can trigger digestive cramps in sensitive dogs.

Parasites such as giardia or roundworms irritate the intestinal wall and lead to recurring colic. Intolerances to food ingredients develop gradually; sudden changes of food within 2-3 days exacerbate the problem.

How do I recognise the symptoms correctly?

The dog shows typical “prayer position” behaviour: front end low, rear end high. It constantly switches between lying down and standing up, turns in circles and cannot find a comfortable resting position.

Abdominal pain manifests as a tucked-up abdomen, tense abdominal wall and sensitivity to touch. Some dogs groan softly when breathing or show strained breathing.

In a Border Collie, the owner initially noticed only increased yawning and licking of the lips, early signs of stress. Within an hour, this developed into classic colic behaviour with restlessness and refusal of its favourite treat.

What immediate measures help?

Withhold food and water immediately. For mild symptoms without emergency signs, you can gently massage the abdomen clockwise for a maximum of 5 minutes.

Give the dog rest, but monitor it continuously. Note the time of the first symptoms, last food and faecal intake as well as all behavioural changes for the vet’s diagnosis.

Warmth from blankets can relax stress-related cramps, but never if gastric torsion (bloat) is suspected; here, warmth further worsens blood circulation.

How does the vet’s diagnosis proceed?

X-rays show within minutes whether the stomach or intestines are abnormally filled. With foreign bodies made of metal or bone, the diagnosis is clear-cut; plastic or fabric often remain invisible.

Ultrasound reveals thickening of the intestinal wall, fluid accumulation and motility disorders. Blood tests show inflammation levels and organ function; in gastric torsion (bloat), certain enzymes rise characteristically.

The faecal examination for parasites usually takes 24-48 hours, but helps identify the cause of chronic complaints.

What treatment options are available?

In emergencies, the vet first stabilises circulation via intravenous infusions. Antispasmodic medications relax the intestinal muscles; painkillers reduce suffering.

Gastric torsion (bloat) requires immediate surgery; the longer you wait, the worse the chances of survival. Foreign bodies are removed endoscopically or surgically.

In bacterial infections, specific antibiotics are effective; modern deworming treatments usually eliminate parasites within 24 hours. Stress-related colic responds to calming medications and environmental adjustments.

How do I prevent colic?

Anti-gulping bowls slow down hasty eaters; several small portions daily put less strain on the stomach than one large meal. After eating, large dogs should rest for at least two hours.

Changing food over 7-10 days prevents digestive disorders. Give treats and chew items only in dog-appropriate sizes; puppies frequently choke on pieces that are too large.

Regular walks promote intestinal movement; stress reduction through fixed routines stabilises sensitive dog stomachs. Quarterly deworming keeps parasites under control without unnecessarily burdening the gut flora.
