Hygroma in Dogs
As dog owners, we want nothing but the best for our furry companions. Unfortunately, our canine friends are susceptible to various health issues, and one of them is hygroma. Hygroma in dogs is a condition that can affect their well-being, comfort, and mobility. In this article, we will delve into what hygroma is, its causes, symptoms, and treatment options to help you better understand and care for your four-legged friend.
What is a Dog Hygroma?
A hygroma, also known as a pressure sore or bursa, is a fluid-filled sac that forms beneath the skin of a dog, typically over bony areas like elbows and hocks. Hygromas are most commonly found in large and giant breed dogs, although they can occur in any breed.
What Are the Types of Dog Hygroma?
Hygromas in dogs are typically categorized based on their location and severity. The two main types of dog hygromas are:
1. Elbow Hygroma
Elbow hygromas are the most common type. They occur on the dog's elbows, which are prone to pressure sores when they rest on hard surfaces for extended periods. Elbow hygromas can develop when the dog's elbows repeatedly rub or press against a hard floor or surface. They often appear as fluid-filled sacs or swellings on the dog's elbows.
2. Hock Hygroma
Hock hygromas are less common but can still occur. They develop on the dog's hocks, which are the equivalent of the human ankle joint and are most often seen in large or heavy-breed dogs. Hock hygromas can also result from repeated pressure or friction on the hock joints, typically when a dog sits or lies on hard surfaces.
In addition to these two main types, hygromas can be classified by their severity or stage of development:
Early Stage Hygromas: In the early stages, a hygroma may appear as a soft, fluid-filled swelling under the skin. It may not be painful to the touch, and the dog might not exhibit any discomfort or lameness at this point.
Advanced Stage Hygromas: If left untreated, hygromas can progress to more advanced stages. In these stages, the hygroma may become larger, firmer, and more painful. It can lead to inflammation, infection, and lameness as it puts pressure on the underlying bone and tissue.
What Causes Hygroma in Dogs?
A hygroma, also known as a bursa, is caused by repeated trauma or pressure to the affected area. Here are some common causes and risk factors for hygromas in dogs:
- Repeated Pressure or Trauma: The most common cause of hygromas in dogs is repeated trauma or pressure to a specific area, often when a dog lies down on hard surfaces such as concrete or tile. Over time, the constant pressure on the joint can lead to the formation of a fluid-filled sac to protect the underlying tissues.
- Large Breed Dogs: Large and giant breed dogs are more prone to developing hygromas due to their heavier body weight and larger joints. Breeds like Great Danes, Mastiffs, and St. Bernards are often affected.
- Thin or Inadequate Padding: Dogs with thin fur or inadequate fat and muscle padding around their joints may be more susceptible to developing hygromas.
- Age: Older dogs may be at a higher risk of developing hygromas due to the cumulative effects of pressure and wear on their joints over time.
- Genetics: Some dogs may have a genetic predisposition to developing hygromas, but the primary trigger is still repeated pressure or trauma to the affected area.
- Hard Surfaces: Dogs that spend a lot of time lying on hard surfaces like concrete or tile floors are at greater risk, especially if they are not provided with soft bedding.
- Excessive Exercise: Dogs engaged in rigorous activities or those that jump and play on hard surfaces may also be at risk, as the repeated impact on their joints can lead to the development of hygromas.
- Obesity: Overweight dogs may experience increased pressure on their joints, making them more susceptible to developing hygromas.
Symptoms of Hygroma in Dogs
Hygromas typically present with the following symptoms:
- Swelling: The affected area will appear as a soft, fluctuant swelling beneath the skin. It is usually painless but can become sore and infected if left untreated.
- Hair Loss: Hair loss may occur over the affected area due to the constant pressure and friction.
- Discomfort: While hygromas may not cause immediate pain, they can become uncomfortable for the dog, especially if they grow in size or become infected.
- Limping or Lameness: If the hygroma is on a joint like an elbow or hock, it can lead to limping or lameness as the dog tries to avoid putting pressure on the affected area.
Hygromas are often bilateral. If the hygroma has been present for a significant length of time, severe inflammation may occur, along with:
- Ulceration
- Infection
- Abscesses
- Granulomas
- Fistulas
- Tissue erosion
Will Dog Hygroma Go Away?
Whether a hygroma will go away on its own depends on the severity of the condition and how well it is managed. In some cases, if you address the underlying cause of the pressure or friction (such as providing a soft bedding surface or adjusting your dog's environment), the hygroma may gradually reduce in size or resolve without any further intervention.
However, in many cases, hygromas may persist or even worsen over time if not properly managed.
Is Hygroma in Dogs Dangerous?
Hygromas are typically not life-threatening, but they can be uncomfortable and, if left untreated, can become infected or lead to more serious complications.
How to Treat Hygroma in Dogs?
A hygroma is a fluid-filled swelling or lump that can develop over a bony area, often on a dog's elbow. It is usually caused by repeated trauma or pressure on that area. Here are some steps you can take if you suspect your dog has a hygroma:
The first and most important step is to consult your veterinarian. They can properly diagnose the hygroma and recommend the best treatment plan for your dog based on its size, severity, and overall health.
Provide Padding
Hygromas are often caused by your dog lying on hard surfaces, which puts pressure on the elbow joints. Provide soft bedding or padding to cushion your dog's joints when they lie down. Make sure your dog has comfortable resting spots to minimize further trauma to the affected area. If your dog spends a lot of time on hard surfaces like concrete or tile, try to limit their exposure to these surfaces. Provide rugs or mats in areas where they frequently lie down.
There are specialized elbow protectors available for dogs that can help cushion and protect the hygroma. These are typically made of soft materials and can be worn on the affected elbow.
Medications
In some cases, your veterinarian may prescribe medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain associated with the hygroma. In the case of infection leading to the formation of a skin ulcer, it's necessary to use supplementary ointments and sprays alongside antibiotics to facilitate the healing process.
Some commonly used NSAIDs for dogs include:
- Carprofen
- Meloxicam
- Deracoxib
- Firocoxib
- Etodolac
- Robenacoxib

Aspiration or Drainage
In certain situations, a veterinarian may recommend draining the fluid from the hygroma through a procedure known as aspiration. This can help reduce the size of the swelling, but it may need to be repeated.
Surgical Intervention
In severe cases or if other treatments are ineffective, your veterinarian may recommend surgical removal of the hygroma. This is typically a last resort and involves excising the swollen tissue and addressing any underlying issues.
How to Prevent Dog Hygromas?
Fortunately, you can take measures to prevent hygromas in your dog by safeguarding their bony areas from injury. This typically involves providing a padded bed for them to rest on instead of a hard floor. This precaution is particularly crucial for dogs with sedentary lifestyles, as prolonged pressure on their elbows and other bony protrusions can increase the risk of hygromas.
Consider this as a great reason to invest in a soft, luxuriously cushioned bed for your furry friend.
If changing your dog's bedding isn't compatible with their lifestyle, you can also explore cushioned sleeves as an alternative to protect their elbows from impacts. This option is especially suitable for active dogs who are frequently on the move. For guidance on using a sleeve and where to purchase one, don't hesitate to consult your veterinarian for recommendations.
Also, make sure that large or giant breed dogs are not overweight or obese. Extra weight can greatly increase the risk of injury to the tissues where the bones protrude.
Hygroma vs Hematoma
The key differences between hygromas and hematomas lie in their causes, characteristics, and treatments. Hygromas are fluid-filled swellings resulting from repeated pressure on bony areas and are typically non-painful, while hematomas are collections of blood due to trauma and are often painful. Treatment involves relieving pressure for hygromas and draining blood for hematomas.
Conclusion
Hygroma in dogs is a condition that can affect their quality of life if left untreated. It is essential for dog owners to be aware of the causes, symptoms, and treatment options for hygromas to ensure the well-being and comfort of their canine companions. If you suspect your dog has a hygroma or notice any unusual swelling or discomfort, consult your veterinarian for a proper diagnosis and guidance on the best course of action to address this condition. With the right care and attention, hygromas can be managed effectively, allowing your dog to live a comfortable and active life.
