As a pet owner, it is not always easy to know whether a change in your dog or cat can wait or needs veterinary attention right away. Pets often hide pain and illness, so even subtle changes in behavior, appetite, breathing, or activity can be important.

At Petvise Animal Hospital in McKinney, Texas, we provide veterinary care for dogs and cats, including wellness visits, same-day sick appointments, urgent care, diagnostics, surgery, dentistry, and ongoing medical treatment.

Knowing a few warning signs can help you decide when it is time to call your veterinarian.

1. Repeated Vomiting or Diarrhea

An isolated episode of vomiting or soft stool may sometimes resolve on its own. However, veterinary evaluation is recommended when vomiting or diarrhea:

  • Happens repeatedly

  • Contains blood

  • Is accompanied by weakness or lethargy

  • Occurs in a puppy, kitten, senior pet, or pet with chronic disease

  • Prevents your pet from keeping water down

  • Continues for more than a short period

Vomiting and diarrhea can be associated with dietary problems, intestinal parasites, pancreatitis, infections, foreign bodies, toxins, and many other conditions.

Your veterinarian may recommend bloodwork, fecal testing, X-rays, ultrasound, medications, or fluid therapy depending on your pet's condition.

2. Difficulty Breathing

Breathing problems should always be taken seriously.

Contact a veterinarian promptly if your dog or cat has:

  • Rapid or labored breathing

  • Open-mouth breathing, especially in cats

  • Blue, gray, or very pale gums

  • Persistent coughing

  • Wheezing

  • Collapse or severe weakness

Respiratory problems may be associated with heart disease, lung disease, airway obstruction, allergic reactions, trauma, or other serious conditions.

Severe difficulty breathing is an emergency.

3. Your Pet Stops Eating

Skipping a single meal does not always indicate a serious problem, but a noticeable loss of appetite can be an early sign of illness.

Dogs or cats that refuse food may be experiencing:

  • Dental pain

  • Gastrointestinal disease

  • Kidney or liver problems

  • Fever or infection

  • Pancreatitis

  • Pain

  • Stress

  • Foreign-body obstruction

  • Other systemic illnesses

Cats deserve particular attention because prolonged lack of food can lead to additional medical problems.

If your pet is refusing food and also vomiting, acting weak, hiding, or showing other abnormal signs, contact your veterinarian.

4. Trouble Urinating

Urinary problems can become emergencies, particularly in male cats.

Warning signs include:

  • Repeatedly entering the litter box

  • Straining to urinate

  • Producing only a few drops of urine

  • Crying or showing pain while urinating

  • Blood in the urine

  • Urinating in unusual locations

  • Excessive licking of the genital area

A completely blocked urinary tract can become life-threatening quickly.

If your cat is repeatedly straining but not producing urine, seek veterinary care immediately.

5. Sudden Weakness, Collapse, or Loss of Balance

Sudden neurological or physical changes should be evaluated promptly.

These may include:

  • Collapse

  • Difficulty standing

  • Walking in circles

  • Head tilt

  • Sudden loss of balance

  • Tremors

  • Seizures

  • Extreme weakness

  • Sudden inability to use one or more legs

The underlying cause can range from metabolic abnormalities and toxin exposure to neurological, cardiovascular, or orthopedic disease.

6. Signs of Pain

Dogs and cats do not always cry when they are hurting.

Signs of pain can include:

  • Shaking or trembling

  • Panting when not hot

  • Hiding

  • Restlessness

  • Reluctance to jump or climb stairs

  • Limping

  • Difficulty getting comfortable

  • Growling when touched

  • Reduced appetite

  • Changes in posture

Persistent or severe pain deserves veterinary evaluation.

Never give your pet human pain medication unless specifically directed by a veterinarian. Medications such as ibuprofen and acetaminophen can be dangerous or even fatal to pets.

7. Eye Problems

Eye problems can worsen quickly and should not be ignored.

Schedule an examination if you notice:

  • Squinting

  • Redness

  • Cloudiness

  • Excessive tearing

  • Yellow or green discharge

  • Swelling

  • Pawing or rubbing at the eye

  • Sudden changes in vision

Corneal ulcers, glaucoma, trauma, infection, and other eye conditions may require prompt treatment to protect your pet's vision.

8. Persistent Ear Problems

Head shaking, scratching, redness, odor, or ear discharge can indicate an ear infection.

Veterinarians commonly perform ear cytology, which involves examining material from the ear under a microscope to identify yeast, bacteria, inflammatory cells, or other abnormalities.

Treating the underlying cause is important because chronic ear infections can become painful and difficult to manage.

9. A Swollen or Painful Abdomen

A suddenly enlarged or painful abdomen can indicate a serious medical problem.

Contact a veterinarian immediately if abdominal swelling is accompanied by:

  • Repeated unsuccessful attempts to vomit

  • Restlessness

  • Excessive drooling

  • Difficulty breathing

  • Weakness

  • Collapse

In large and deep-chested dogs, these symptoms can be associated with gastric dilatation-volvulus (GDV or bloat), which requires emergency treatment.

10. Your Pet Is Simply “Not Acting Normal”

Pet owners know their animals better than anyone.

Sometimes there is no dramatic symptom. Your pet may simply be:

  • Sleeping more than normal

  • Hiding

  • Less interested in playing

  • Drinking more water

  • Losing weight

  • Acting restless

  • Becoming unusually clingy

  • Showing changes in bathroom habits

These changes can provide valuable clues.

When something seems unusual, contacting your veterinarian early is often better than waiting for the problem to become more severe.

When Is It an Emergency?

Seek immediate veterinary attention for problems such as:

  • Severe difficulty breathing

  • Collapse or loss of consciousness

  • Uncontrolled bleeding

  • Major trauma

  • Repeated seizures

  • Suspected poisoning

  • Inability to urinate

  • Severe abdominal swelling

  • Heatstroke

  • Severe allergic reaction

  • Persistent vomiting with weakness

  • Pale, blue, or gray gums

If you are uncertain whether your pet's condition is urgent, call a veterinary hospital and describe the symptoms.
