Before travelling
We have not visited the clinics or evaluated treatment. Prices, languages spoken and response times are not published in a comparable form, so we do not rank them.
- When calling, state the animal’s species, the problem and your arrival time, and confirm that a vet is on duty.
- Ask about emergency consultation, tests, admission and payment methods before authorising costs.
- Save the exact address and choose a clinic that can receive your animal in time.
