On-call vets in Belgium: how it works, who to call, when to worry

In the evening, at the weekend or on a public holiday, how to find an on-call vet in Belgium, what an emergency consultation costs and the signs that cannot wait.

A dog vomiting at 11 pm, a cat that will not get up on a Sunday: the veterinary on-call service exists for this. Here is how it works in Belgium.

How the on-call service is organised

Vets in an area share on-call duties on a rota. Most often:

  1. Call your usual vet first: their answering machine gives the number of the colleague on duty or of the regional central service.
  2. Phone before travelling: the on-call vet may be on a call-out, and will tell you what to do in the meantime.
  3. 24/7 emergency clinics: in large cities, some facilities accept patients at any hour without appointment.

What an on-call consultation costs

An on-call visit carries a surcharge (night, weekend, public holiday) on top of the care. Amounts vary between practices; ask for an estimate on the phone.

Signs that cannot wait

  • Breathing difficulties, blue or white gums.
  • Repeated vomiting or diarrhoea with lethargy, especially in a puppy or kitten.
  • Swollen, hard abdomen, unproductive retching in a large dog (risk of gastric torsion).
  • Male cat unable to urinate.
  • Seizures, loss of consciousness, trauma (car, fall).
  • Ingestion of chocolate, grapes, xylitol, medication, antifreeze, toxic plants.

When in doubt, call: describing the symptoms on the phone lets the vet decide.

Preparing the call

Have the animal's age, weight, current treatments and vaccines to hand, plus its chip number. With Zoolinko, the full health record is on your phone, and you can give the on-call vet temporary 72-hour access to the file, which you revoke afterwards.
