What Is Lymphangiectasia in Dogs?

Lymphangiectasia in dogs is a condition that involves the lymphatic system. The lymphatic system plays a crucial role in transporting lymph and fluid that are important components in helping to fight infections and maintain fluid balance in the body. When lymphangiectasia happens, the lymphatic vessels become enlarged, and pets can develop digestive problems. As it can affect the body’s overall well-being, understanding how this condition impacts the lymphatic system and the digestive system is crucial.

Symptoms & Causes

Knowing some of the symptoms is very important as you can help your little one and look for medical help sooner than later. For example:

Diarrhea: Instances may vary from mild to severe. It may be intermittent (stopping and returning in intervals).
• Weight Loss: Pets may lose body weight due to the malabsorption of nutrients.
• Swelling: Swelling may occur in the abdominal area, where fluid accumulates.

There are various causes that can lead to lymphangiectasia like genetic predisposition. For instance, certain breeds like Yorkshire Terriers and Basenjis may be more prone to have this condition. Evidence suggests that chronic inflammations, infectious diseases, and/or tumors also play a role on the development of lymphangiectasia in dogs.

Diagnosis

Prompt consultation with a veterinarian is required when lymphangiectasia in dogs is suspected. Several diagnostic laboratory tests may help confirm the diagnosis:

Blood Work: This helps to see if your fur baby has low protein levels for example.
• Imaging: Such as X-rays or ultrasounds can give a view of the organs in the abdomen and check for any anatomic abnormalities.
• Biopsy: In some cases, a tissue sample need to be collected and send to a pathologist to confirm lymphangiectasia and rule out other possible conditions such as lymphoma for example.

Note that having the correct diagnosis can help choosing the correct treatment plan and help improve the comfort and health outcomes of the pet.

Treatment Options for Lymphangiectasia in Dogs

Treating lymphangiectasia can include a combination of changes of many factors, such as changes in the diet, vet-prescribed medications, and supportive care such as supplements. Examples include:

• Changes in the diet: A diet low in fat content may help decrease the stress suffered by the lymphatic system. Some dogs also may benefit from a high quality digestible food that can support the absorption of nutrients
Medications: Vet-prescribed medication may help manage the symptoms and reduce inflammation caused by this condition
