Understanding Abnormal Growths in the Lower Intestines of Dogs

Abnormal growths in a dog’s lower intestines can cause significant health concerns, ranging from discomfort to life-threatening conditions. These growths, often located in the rectum or colon, can be benign or malignant. Understanding their causes, symptoms, and treatment options is crucial for timely intervention.

Common Types of Growths

1. Polypen
   • Polyps are benign growths that develop in the lining of the intestines.
   • They may cause minor bleeding, diarrhea, or constipation.
   • If untreated, polyps can sometimes transform into malignant tumors.
2. Adenokarzinom
   • A malignant tumor affecting the glandular cells lining the intestine.
   • This is one of the most aggressive types of lower intestinal cancers.
   • Early detection is critical for effective treatment.
3. Leiomyosarkom
   • A rare type of cancer that originates in the smooth muscle of the intestines.
   • It can cause obstruction and severe digestive issues.
4. Hemangiomas and Hemangiosarcomas
   • These vascular tumors can either be benign (hemangiomas) or malignant (hemangiosarcomas).
   • They often lead to bleeding and anemia.

Symptoms of Abnormal Growths

Dogs with abnormal growths in the lower intestines may exhibit the following symptoms:

• Blood in Stool: Bright red or tar-like black stool.
• Straining to Defecate: Difficulty or pain during bowel movements.
• Changes in Stool Shape: Narrow or ribbon-like stool due to obstruction.
• Diarrhea or Constipation: Persistent changes in bowel habits.
• Weight Loss: Unexplained loss of weight and appetite.
• Vomiting or Lethargy: Indications of gastrointestinal distress.

Ursachen und Risikofaktoren

While the exact cause of abnormal growths varies, some contributing factors include:

• Diet: Poor-quality or processed diets may contribute to inflammation and tumor development.
• Age and Genetics: Older dogs and certain breeds like Boxers and German Shepherds are more prone to intestinal tumors.
• Chronische Entzündung: Conditions like colitis may predispose dogs to growths.
• Exposure to Toxins: Environmental toxins and carcinogens can increase cancer risk.

Diagnose

Veterinarians use a combination of methods to diagnose intestinal growths:

• Körperliche Untersuchung: Palpation to identify masses.
• Bildgebung: X-rays, ultrasounds, or CT scans to visualize growths.
• Endoskopie: Insertion of a camera to examine the intestines and collect tissue samples.
• Biopsie: Lab analysis of tissue to determine if the growth is benign or malignant.

Behandlungsmöglichkeiten

The treatment approach depends on the type and severity of the growth:

1. Operative Entfernung: Polyps and localized tumors can often be removed surgically.
2. Chemotherapie oder Strahlentherapie: Used for malignant growths, particularly adenocarcinoma.
3. Dietary Management: High-fiber or prescription diets to manage symptoms.
4. Palliativpflege: Pain relief and quality-of-life management for advanced cases.

Prävention und Überwachung

• Regelmäßige Kontrolluntersuchungen: Routine veterinary visits can help detect growths early.
• Healthy Diet: A diet rich in natural, high-quality ingredients can reduce inflammation.
• Screening in At-Risk Breeds: Periodic screenings for breeds prone to intestinal issues.

Wann Sie einen Tierarzt aufsuchen sollten

If your dog shows signs of rectal bleeding, chronic digestive problems, or significant changes in stool, it’s essential to consult a veterinarian promptly. Early diagnosis and treatment can dramatically improve outcomes.

By staying informed and proactive, pet owners can better safeguard their dogs’ health and address potential problems before they escalate.
