Gallarus

Good morning This is my first post. Maya is 4 years old. We're planning to travel from Scotland to Belfast and on to the southwest in late December 21. The vet told me this morning that she can't make entries on Maya's EU passport, post Brexit. Therefore, a Health Cert is required and is going to cost £150! And will be required anew for each trip. Is this info correct? It's a reputable vet practice. Has anyone found a way around or a cheaper option? All the best, Gallarus
