Swelling

Swelling is a common condition in dogs that can have various causes. In this article, you'll learn what swelling is, how to recognize it and what you can do to help your dog.

What is swelling?

Swelling is an accumulation of fluid or tissue in a body part or organ. It can be caused by inflammation, infection, injury, allergies or other factors. Swelling can be acute or chronic, depending on how long it lasts and how severe it is.

How do you recognize swelling in dogs?

Swelling can manifest itself in different ways depending on the part of the body affected. The most common signs are

  • Enlargement or deformation of the body part
  • Redness or warmth of the skin
  • Pain or tenderness to the touch
  • Itching or irritation of the skin
  • Restriction of movement or lameness
  • Loss of appetite or lethargy

Swelling can also affect internal organs such as the heart, lungs, liver or kidneys. In this case, other symptoms may occur, such as

  • Shortness of breath or coughing
  • Palpitations or cardiac arrhythmia
  • Vomiting or diarrhea
  • Weight loss or water retention
  • Blood in the urine or stool
  • Jaundice or paleness

What are the possible causes of swelling in dogs?

Swelling in dogs can have many different causes, ranging from harmless to life-threatening. Some of the most common are:

  • Insect bites or stings: These can trigger an allergic reaction that can lead to swelling on the face, ears, paws or all over the body. The swellings can be itchy, painful or hot to the touch. In severe cases, breathing difficulties, shock or anaphylaxis may also occur.
  • Abscesses: These are pus-filled inflammations under the skin, usually caused by bacteria. They can form anywhere on the body, but are particularly common in the mouth, head or anal area. Abscesses can burst and leave an open wound that can easily become infected.
  • Tumors: These are uncontrolled growths of cells that can be benign or malignant. They can form in any tissue or organ and cause swelling. Tumors can also affect other organs or form metastases that can spread throughout the body.
  • Trauma: These are injuries caused by accidents, falls, bites or other acts of violence. They can lead to bruising, contusions, bruises or fractures that can cause swelling. Trauma can also cause internal bleeding or organ damage, which can be life-threatening.
  • Autoimmune diseases: These are conditions in which the dog's immune system mistakenly attacks its own cells. They can lead to inflammation and swelling in various parts of the body. Some examples are lupus, rheumatoid arthritis or Addison's disease.

The authors assume that a veterinarian should be consulted if an animal is ill and that medication should only be taken after consultation with a doctor or pharmacist. Only an individual examination can lead to a diagnosis and treatment decision.
