As a dog owner, it’s essential to keep an eye on your furry friend’s health.
Dogs can’t tell us how they feel, so we must be vigilant in looking for signs of illness.
In this article, we’ll explore seven common signs that your dog might be sick and what you can do about them.
7 Signs Your Dog Might Be Sick and What You Can Do About It

Lethargy

Lethargy is a state of sluggishness, fatigue, or lack of energy. Dogs may display lethargy when they’re feeling unwell, making it an essential sign to watch for.
- How to detect lethargy in your dog
It’s crucial to know your dog’s normal energy levels. Lethargy might manifest as your dog being less interested in playing, having difficulty getting up, or sleeping more than usual.
- When to consult a veterinarian
If your dog’s lethargy lasts more than 24 hours or is accompanied by other symptoms, contact your veterinarian immediately.
Loss of Appetite

Loss of appetite in dogs can result from various factors, including dental problems, gastrointestinal issues, and infections. A sudden change in diet or stress may also cause a temporary decrease in appetite.

If your dog hasn’t eaten for more than 24 hours or consistently eats less than usual, consult your veterinarian. Prolonged loss of appetite can lead to malnutrition and other complications.
Vomiting and Diarrhea

Vomiting and diarrhea are common symptoms of various health issues, including food intolerance, gastrointestinal infections, and ingestion of toxic substances.

Dogs may exhibit behavioral changes when they’re not feeling well, such as increased aggression, withdrawal, or signs of discomfort.
