Pets can’t explain when something feels wrong, so small changes in their routine may be important clues. A skipped meal, lower energy, unusual behavior, or signs of discomfort can have many causes, and one change alone does not always mean an emergency. Pay attention to what is different, how long it lasts, and whether symptoms are getting worse. Knowing when to call your veterinarian can help you respond promptly and give your pet the right care.
Watch appetite and drinking
A sudden loss of interest in food, eating much less than usual, or refusing favorite treats may signal that your pet is unwell. So can a noticeable increase in appetite. Consider whether a recent change in food, routine, or environment might explain the difference, but don’t assume that is the cause if the change persists or comes with other symptoms.
Changes in thirst or urination matter, too. Drinking much more or less than usual, having accidents indoors, or making repeated trips to the litter box are worth discussing with a veterinarian. Contact your clinic for guidance if your pet stops eating, especially if they are very young, elderly, or have a known health condition. Seek prompt advice if appetite changes occur alongside vomiting, diarrhea, weakness, or pain.
Notice energy and breathing
A pet who sleeps more, avoids play, struggles to climb stairs, or tires quickly may be feeling unwell or uncomfortable. Compare their activity with their normal pattern rather than with another animal. Note when the change began and whether it is steady, improving, or worsening.
Breathing problems need urgent attention. Get veterinary help right away for labored or unusually rapid breathing, blue or pale gums, collapse, or difficulty waking your pet. If energy is lower but your pet is breathing comfortably and can move around, call your veterinarian to describe the change and ask how soon they should be seen.
Look for behavior changes
Hiding, irritability, restlessness, clinginess, or avoiding touch can be signs of stress or discomfort. A normally social pet who withdraws, or a calm pet who becomes unusually reactive, may be telling you that something has changed. Avoid scolding or forcing contact; give them a quiet place and observe what triggers the behavior.
Keep track of new habits such as excessive licking, scratching, pacing, vocalizing, or confusion. Mention any recent changes in the home, diet, medication, or routine when you call the clinic. Sudden behavior changes accompanied by weakness, disorientation, seizures, or possible exposure to a toxin call for immediate veterinary advice.
Check comfort and act promptly
Watch for limping, stiffness, a hunched posture, flinching, trembling, or reluctance to jump or be picked up. Other clues include repeated vomiting, diarrhea, coughing, unusual discharge, or a swollen belly. Your pet may hide pain, so a change in movement or daily habits can be more noticeable than crying or whining.
Call a veterinarian when a symptom persists, returns, worsens, or affects eating, drinking, walking, or resting. Seek urgent care for severe pain, heavy bleeding, repeated retching without bringing anything up, inability to urinate, suspected poisoning, or trouble breathing. Don’t give human medication unless a veterinarian specifically tells you to; some common medicines can harm pets.
You know your pet’s usual routines best. Write down what changed, when it started, and any related symptoms, then share those details with your veterinarian. If you’re unsure whether a change can wait, call a clinic for guidance. Austin Care Vet can help you decide on an appropriate next step.
