What pet symptoms require emergency vet care?

Take your pet to an emergency vet immediately for: difficulty breathing or blue gums, collapse, suspected poisoning, seizures, a distended hard abdomen (dogs — possible bloat), sudden paralysis, uncontrolled bleeding, urinary blockage in cats (straining with no urine output), severe trauma, or sudden vision loss. Do not wait for morning.

When should I call the vet urgently (within 24 hours)?

Call your vet same-day for: persistent vomiting or diarrhea (3+ episodes), complete appetite loss for 24-48 hours, limping that doesn't improve with rest, eye cloudiness or discharge, a new lump that appeared suddenly, significant change in thirst or urination, an infected wound, or a painful abdomen.

Is a urinary blockage in a cat an emergency?

Yes — a urinary blockage in a cat is a life-threatening emergency. If your cat is straining in the litter box but producing little or no urine, go to an emergency vet immediately. Without treatment, a complete blockage can be fatal within 24-48 hours.

When should senior pets see the vet sooner?

For pets over 10, err on the side of calling your vet sooner rather than later. Age-related conditions progress quickly, and what appears to be 'just slowing down' may be a treatable condition. When in doubt, call your vet — most practices will help you triage symptoms over the phone.

When Should You Take Your Pet to the Vet?

Not every symptom is an emergency — but some are. This guide helps you decide between "go now," "call tomorrow," and "watch and wait."

Emergency: Go to the Vet NOW

These symptoms require immediate emergency care. Do not wait for morning. Call ahead so they can prepare.

Difficulty breathing, gasping, blue gums
Collapse or inability to stand
Suspected poisoning or toxin ingestion
Seizures (first seizure or multiple in 24 hrs)
Distended, hard abdomen (dogs — possible bloat)

Sudden paralysis or inability to use limbs
Profuse or uncontrolled bleeding
Urinary blockage (cats — straining with no output)
Severe trauma (hit by car, fall from height)
Sudden loss of vision

Persistent limping in older pets often signals joint issues — our pet joint health guide explains what's treatable and when it warrants urgent attention.

A Note on Senior Pets

For pets over 10, err on the side of calling your vet sooner rather than later. Age-related conditions can progress quickly, and what looks like "just slowing down" may be a treatable condition caught early enough to make a real difference. For detailed home monitoring guidance, see our senior dog care guide and our senior cat care guide for age-specific warning signs.

When in doubt, call your vet and describe the symptoms. Most practices are happy to help you triage over the phone.
