2. Unexplained Weight Loss

Sudden or unexplained weight loss is a significant red flag for potential health issues, including cancer. If your dog is losing weight despite maintaining a healthy diet and exercise routine, it could indicate an underlying problem.

Key Points to Consider:

• Appetite Changes: Monitor your dog’s eating habits. A decrease in appetite or difficulty eating can be a symptom of oral tumors or gastrointestinal cancers.
• Muscle Wasting: Noticeable muscle loss, particularly around the hindquarters, can be indicative of systemic illness.
• Energy Levels: A dog with cancer may exhibit decreased energy levels and lethargy, which can accompany weight loss.

3. Persistent Coughing or Difficulty Breathing

Persistent coughing or difficulty breathing can be a sign of lung cancer or other respiratory issues. While occasional coughing can be due to benign causes like allergies or infections, chronic coughing requires veterinary evaluation.

Key Points to Consider:

• Cough Characteristics: Pay attention to the nature of the cough. A dry, hacking cough can be different from a moist, productive one.
• Breathing Patterns: Observe your dog’s breathing. Labored or rapid breathing, wheezing, or shortness of breath are concerning signs.
• Associated Symptoms: Look for other symptoms like nasal discharge, sneezing, or coughing up blood, which may indicate more severe issues.
