At Manor Veterinary Hospital, we care for pets from Manor and Elgin, TX with everything from routine checkups to urgent care. And one of the most important things we teach our clients is how to recognize the early signs of illness in pets. Your dog or cat can’t tell you what’s wrong, but they will show you—if you know what to look for.

If you’ve ever wondered how to know if your pet is sick, this guide is for you. Catching symptoms early can lead to faster treatment, lower costs, and better outcomes for your four-legged friend.

Behavior Changes Are Often the First Clue

Trust Your Gut—You Know Your Pet Best

If your normally energetic pup seems tired, or your feline friend starts hiding more than usual, take notice. Many early symptoms of illness in dogs and cats begin as slight shifts in behavior.

Watch for:

• Lethargy or unusual restlessness
  
• Hiding, withdrawal, or clinginess
  
• Irritability or sudden aggression
  
• Changes in sleep patterns or vocalizations
  

These changes can indicate anything from pain to infection—and they’re one of the top reasons we recommend regular exams at our veterinary clinic near Elgin.

Eating, Drinking, and Bathroom Changes

Appetite and Elimination Tell a Big Story

Any sudden changes in how much your pet eats, drinks, or uses the bathroom may mean it’s time to call your vet.

Look out for:

• Loss of appetite or refusal to eat
  
• Increased thirst or urination
  
• Vomiting or diarrhea
  
• Straining, scooting, or missing the litter box
  

Don’t wait days to see if it resolves on its own. These symptoms can escalate quickly, and early intervention from our Manor vet clinic can prevent complications.

Breathing Issues and Nasal Discharge

If It Sounds Off, It Probably Is

Coughing, sneezing, or heavy breathing may point to infections, allergies, or heart and lung problems. Even indoor cats can develop respiratory issues.

Common signs include:

• Persistent coughing or sneezing
  
• Wheezing or labored breathing
  
• Runny or crusty nose
  
• Unusual snoring or gagging
  

Let our vets near Elgin examine your pet to determine what’s behind the noise—and how to treat it safely.

Skin, Eyes, and Coat Clues

What You Can See Often Reflects What You Can’t

Skin and coat changes are visible signs that something inside your pet might be off.

Check for:

• Excessive itching or licking
  
• Red or inflamed skin
  
• Eye discharge or swelling
  
• Dull coat or hair loss
  

If you’re noticing these symptoms, we can run diagnostic tests at Manor Veterinary Hospital to pinpoint the cause—be it parasites, infection, or allergies.

Unexplained Weight Changes

Don’t Ignore Subtle Shifts

Rapid weight gain or loss without a clear reason is always a red flag. It can point to metabolic issues, thyroid problems, digestive trouble, or more serious diseases.

Call us if you notice:

• Weight loss despite normal eating
  
• Increased appetite but poor energy
  
• Bloating or a pot-bellied appearance
  
• Visible bones or a tight belly
  

When to call the vet for your pet? If you’re asking yourself that question more than once—just give us a ring. We’d rather catch something early than too late.

Emergencies vs. Wait-and-See

Know When to Act Fast

Some signs mean you should bring your pet in immediately. These include:

• Difficulty breathing
  
• Collapsing or sudden weakness
  
• Seizures or uncontrolled shaking
  
• Swollen or hard abdomen
  
• Bleeding that won’t stop
  

In these cases, skip the guesswork and call Manor Veterinary Hospital or head straight to an emergency veterinary clinic near you.
