Reading the signs: eight symptoms every dog and cat owner should recognize

DJDr. James Okafor, DVM · May 30, 2026 · 7 min read

Pets cannot tell you where it hurts, so they tell you in behavior. Learning to read a few common signals turns a vague sense that something is off into information you can act on, and share with your vet.

Changes in eating and drinking

A single skipped meal is usually nothing. A pattern is information. Drinking much more than usual can point to kidney or hormone issues; a sudden stop, especially in cats, is worth a same-day call.

Energy and posture

Lethargy is one of the most honest signals a pet gives. A dog that will not get up for a walk, or a cat that hides in a way it never does, is telling you something. Note it, time it, and watch whether it deepens.

Breathing and coughing

Count the breaths of a resting pet: more than 35 to 40 a minute at rest deserves attention. Effort matters more than speed. A belly that heaves, or an open mouth in a cat, is an emergency signal.

Gut signs: vomiting and diarrhea

  • One episode, otherwise bright: usually watch and wait.
  • Repeated, or with blood, or with a bloated belly: go now.
  • Ongoing past a day, or a quiet and off pet: call your vet.

Movement: limping and stiffness

Whether a pet will bear weight on a limb is the fastest triage signal you have. Favoring a leg is usually a wait. Holding it up entirely, or a limp that arrived with a yelp, means a hands-on exam.

The skin, eyes, and gums

Gum color is a quiet vital sign: healthy pink is good, pale or bluish is not. Eyes that are suddenly squinting, cloudy, or weeping change fast and are worth a prompt call.

None of this replaces an exam. The goal is to notice earlier, describe better, and get to a vet at the right time, not to diagnose at home.

Keep a running note of what you see and when. In Vetta, that note becomes part of the record and rides along to your next visit, so the vet starts with the full picture instead of a retelling.
