Spain doesn't have one central pet-emergency phone number the way it does for human emergencies (112). Instead, most regular veterinary clinics (clínicas veterinarias) either run their own out-of-hours service or refer after-hours calls to a dedicated emergency clinic, and that referral number is usually on the practice's own answering message or website.

If you're staying somewhere for more than a day or two, save a local vet or emergency number as soon as you arrive rather than searching for one mid-emergency. Searching "veterinario urgencias" or "urgencias veterinarias" plus your city is the quickest way to find a nearby emergency clinic if you're starting from nothing.

Have a payment method ready for an unplanned, larger charge, since most Spanish practices expect payment at the time of treatment rather than billing afterward, which is the standard arrangement across most of Europe for pet care.
