Signs of Illness in Cats and Dogs You Should Never Ignore

Cats and dogs can’t speak, so it’s essential to pay close attention to changes in their behavior or health. According to Dr. Nancy Nasr, early detection of warning signs can make a significant difference in diagnosis and treatment—and may even save your pet's life.

1. Sudden Loss of Appetite

If your cat or dog stops eating for more than 24 hours, it could indicate issues such as dental problems, liver disease, or kidney disorders.

???? Tip from Dr. Nancy Nasr: Track your pet’s daily food intake and note any changes.

2. Lethargy or Lack of Energy

If your pet becomes less active or refuses to play, it could be due to internal pain or conditions affecting the heart or respiratory system.

3. Frequent Vomiting or Diarrhea

Ongoing vomiting or diarrhea may signal poisoning, internal parasites, or digestive tract issues.

???? Important Warning: Never give human medications without veterinary advice.

4. Difficulty Breathing or Persistent Cough

Abnormal breathing sounds, constant coughing, or excessive panting could indicate heart or lung disease and require immediate attention.

5. Changes in Gum or Tongue Color

Pale, bluish, or yellowish gums may point to blood disorders, liver issues, or low oxygen levels.

???? Tip from Dr. Nancy Nasr: Regularly check your pet’s gum color, especially if they’re unwell.

6. Excessive Scratching or Hair Loss

These symptoms may suggest allergies, fungal infections, or parasites like fleas or ticks.

7. Bad Breath or Unusual Discharge

Foul-smelling breath can be a sign of dental disease or gastrointestinal issues. Nasal or eye discharge may indicate infection.

8. Increased Thirst or Urination

Drinking and urinating more than usual can signal conditions like diabetes or kidney problems.
