When does my dog need the tapeworm treatment?

Between 24 and 120 hours before arriving in Great Britain. Less than 24 hours is too soon, more than 5 days is too late.

Do I need tapeworm treatment to take my dog to Spain?

No. It applies only to dogs entering Great Britain, so it affects the journey home.

Can my UK vet do it before we leave?

No. The window is measured against arrival in Great Britain, so the treatment happens in Spain shortly before the return journey.

Can I give a worming tablet myself?

No. It has to be given by a vet, contain praziquantel or a proven equivalent, and be recorded in the travel document with the date, time, product, stamp and signature.

Tapeworm treatment for the journey home

Dogs entering Great Britain need a tapeworm treatment given by a vet no less than 24 hours and no more than 120 hours before they arrive. Five days at the outside, one day at the minimum.

Cats and ferrets do not need it. Neither does any animal travelling in the other direction, so nothing is required for the outbound trip to Spain.

The timing is the difficult part

Look at that window against a road journey from the Costa Blanca to the UK and the problem is obvious. The treatment has to happen in Spain, at a Spanish vet, in the days immediately before your dog gets on the road.

It cannot be done at home in the UK before you set off, because the window is measured against the moment you arrive back, and a trip to Spain never fits inside 120 hours. It cannot be done after arrival either. The treatment sits inside the journey.

So it has to be booked before you leave. When we plan a return trip we tell you the exact date range for the appointment, worked back from the arrival time in the UK, and we ask for a copy of the completed page before departure. If you have a regular vet in Spain, book it with them as soon as your return date is fixed. In August, appointments go quickly.

What the vet has to record

The treatment must contain praziquantel, or an equivalent proven to work against the Echinococcus multilocularis tapeworm. A general worming tablet from a pet shop does not count and will not be accepted.

The vet records four things in the Echinococcus section of the travel document:

the name and manufacturer of the product
the date and the time of treatment
their stamp
their signature

The time matters as much as the date. The window is measured in hours, and a missing time makes it impossible for an official to confirm the treatment falls inside it. Check that the time is written down before you leave the practice.

Which countries are exempt

There is no tapeworm requirement for a dog coming directly to Great Britain from Finland, Ireland, Northern Ireland, Malta or Norway. Spain is not on that list, so your dog needs the treatment.

What happens if the window is missed

Your dog can be refused entry or put into quarantine. On a ferry route that in practice means the dog stays on the French side while a fresh treatment is given and another 24 hours are waited out, at your cost.

It is the most avoidable failure on this whole checklist, and it is avoidable in one step: book the Spanish appointment at the same time as you book the transport.
