When Should You Take Your Pet to the Vet? A Guide to Common Symptoms 

Pet owners often notice small changes before anyone else would. Maybe your dog skips breakfast, your cat spends more time hiding, or your normally energetic pet suddenly seems a little off. 

The difficult part is knowing what that change means. Is it something you can watch for a day, something that deserves a call to your veterinarian, or something that needs attention right away? 

There is no single rule that applies to every pet or every situation. Age, medical history, how long a symptom has been happening, and whether other symptoms are present can all affect how concerned you should be. Knowing a few common warning signs can help you make a more informed decision. 

Changes in Eating or Drinking 

A change in appetite for a single meal does not necessarily mean something is wrong. Pets may occasionally eat less because of stress, a change in routine, mild stomach upset, or even simply being less active than usual. 

What matters is how significant the change is, how long it lasts, and what else you are noticing. 

Consider contacting your veterinarian if your pet: 

  • Refuses food or continues eating significantly less than usual 
  • Suddenly begins drinking much more or less than normal 
  • Seems interested in food but has difficulty chewing, swallowing, or picking it up 
  • Vomits repeatedly after eating or drinking 
  • Suddenly loses interest in foods or treats they normally enjoy 
  • Has an appetite change along with weight loss, lethargy, vomiting, diarrhea, or another change in behavior 

Increased thirst can be particularly important to mention to your veterinarian. It can occur with a number of medical conditions, including kidney disease, diabetes, and hormonal disorders. Your veterinarian may recommend an examination or diagnostic testing based on your pet’s age, history, and other symptoms. 

Vomiting or Diarrhea 

Dogs and cats occasionally have digestive upset, and a single episode of vomiting or loose stool in an otherwise bright, comfortable pet may not require an immediate visit. 

Repeated or severe symptoms are different. 

Contact your veterinarian if vomiting or diarrhea continues, happens frequently, or is accompanied by symptoms such as lethargy, loss of appetite, abdominal discomfort, weakness, or blood in the vomit or stool. 

Repeated vomiting can also make it difficult for a pet to stay hydrated. If your pet cannot keep water down, that deserves prompt attention. 

Puppies, kittens, senior pets, and animals with existing medical conditions can become dehydrated or seriously ill more quickly, so your veterinarian may recommend evaluating them sooner. 

Sudden Changes in Behavior 

Not every sign of illness looks like an illness. 

Dogs and cats cannot tell us that something hurts or that they feel nauseated. Instead, they may communicate discomfort through changes in their normal behavior. 

You might notice that your pet: 

  • Hides or withdraws from the family 
  • Becomes unusually irritable or sensitive to touch 
  • Seems restless and cannot get comfortable 
  • Sleeps considerably more than usual 
  • Stops greeting you or participating in normal activities 
  • Suddenly has accidents in the house 
  • Vocalizes more or less than usual 

The important word here is change. You know what is normal for your pet. A noticeable change from normal behavior can provide useful information, even when there are no obvious physical symptoms. 

Difficulty Breathing 

Changes in breathing should be taken seriously. 

A pet who is struggling to breathe, breathing with significant effort, or showing signs of respiratory distress needs immediate veterinary attention. 

Watch for signs such as open-mouth breathing in a cat, increased abdominal effort while breathing, an inability to settle comfortably, pale or bluish gums, or obvious difficulty getting enough air. 

Heavy panting after exercise or on a hot day is different from respiratory distress, but if your pet’s breathing seems abnormal for the circumstances or does not return to normal with rest, contact a veterinary professional. 

Pain or Difficulty Moving 

Pain in pets is not always obvious. Many dogs and cats instinctively hide discomfort, so you may never hear them cry or see an obvious reaction. 

Instead, pain may look like: 

  • Limping or favoring a leg 
  • Stiffness, particularly after resting 
  • Difficulty standing up or lying down 
  • Reluctance to use stairs or jump onto furniture 
  • Moving more slowly than usual 
  • Avoiding walks, play, or other favorite activities 
  • Flinching or moving away when touched 
  • Repeatedly licking one area of the body 

A sudden inability to stand, walk normally, or use a limb warrants immediate attention. More gradual changes should also be discussed with your veterinarian, particularly if they persist or begin interfering with your pet’s normal activities. 

Changes in Urination 

Changes in bathroom habits can provide important clues about your pet’s health. 

Pay attention to how frequently your pet urinates, whether the amount has changed, and whether they appear comfortable doing it. 

Contact your veterinarian if you notice blood in the urine, frequent accidents, straining, unusually frequent urination, or a significant increase or decrease in urine production. 

Repeatedly attempting to urinate while producing little or no urine can be an emergency, particularly in male cats. If you see this behavior, seek veterinary care promptly rather than waiting to see if it improves. 

Eye Problems 

Eye problems can change quickly, and some conditions are painful even when a pet does not show obvious signs of discomfort. 

Squinting, keeping an eye closed, significant redness, cloudiness, swelling, excessive tearing, discharge, or a sudden change in the appearance of the eye are all reasons to contact your veterinarian. 

Eye injuries and certain eye conditions can become more difficult to treat if care is delayed, so this is one area where it is generally better to ask sooner rather than later. 

When Is It an Emergency? 

Some symptoms should not be monitored at home while you wait to see what happens. 

Seek immediate veterinary care if your pet is experiencing significant difficulty breathing, collapse or loss of consciousness, uncontrolled bleeding, repeated seizures, severe trauma, a severely swollen or painful abdomen, suspected poisoning, inability to urinate, or another sudden and severe change in condition. 

If you are unsure whether a situation is urgent, call a veterinary professional and describe exactly what you are seeing. They can help you determine the appropriate next step. 

You Don’t Have to Diagnose the Problem Yourself 

One of the hardest parts of caring for a pet is that they cannot tell you exactly how they feel. 

Your job is not to figure out the diagnosis before calling the veterinarian. Your observations are enough. When did the change start? Is it getting better or worse? Is your pet eating and drinking? Are they behaving normally? Are there any other symptoms? 

Those details can help your veterinary team understand what is happening and determine whether your pet should be seen. 

At Mauldin Station Vet, we believe good veterinary care includes helping you understand the why behind our recommendations. If your pet needs an examination, diagnostic testing, treatment, or simply careful monitoring at home, our goal is to explain what we know, what we are looking for, and what your options are. 

Because knowing what is happening is an important part of knowing how to care for your pet.
