Stopping a bleeding lump on your dog naturally requires a gentle approach. The first step is to apply a cold compress to the affected area to constrict the blood vessels and reduce bleeding.
A cold compress can be made by wrapping an ice pack in a towel and applying it to the lump for 10-15 minutes at a time, with 30-minute breaks in between. This can be repeated several times a day.
In some cases, a bleeding lump on your dog may be caused by a minor cut or scratch that has become infected. To prevent future outbreaks, it's essential to keep an eye on your dog's skin and monitor for any signs of infection, such as redness, swelling, or discharge.
By taking a proactive approach to your dog's skin health, you can help prevent bleeding lumps from occurring in the first place.

Causes and Types
A bleeding lump on your dog can be caused by a variety of factors, including trauma, infection, or a tumor.
Trauma, such as a cut or bite, can cause bleeding and swelling, which may lead to a lump forming on your dog's skin.
Infection, like pyoderma, can cause a painful lump on your dog's skin, which may bleed if scratched or irritated.
Tumors, such as mast cell tumors, can also cause a lump on your dog's skin, which may bleed if it ruptures or becomes infected.

Hemangiosarcoma –
Hemangiosarcoma is a type of cancer that affects the blood vessels. These tumors frequently cause the affected vessel(s) to rupture and bleed. Most commonly, hemangiosarcoma affects internal organs, with the spleen, liver, and heart being the most common sites.
The symptoms of hemangiosarcoma can be subtle, but they may include weakness, lethargy, and pale gum color due to internal bleeding.
Hemangiosarcoma can be diagnosed through a combination of physical examination, complete blood count, serum biochemical profile, urinalysis, coagulation profile, and diagnostic imaging such as chest radiography and abdominal radiography.
The treatment of hemangiosarcoma depends on the location of the tumor. Surgical removal of dermal hemangiosarcoma can be curative, but visceral hemangiosarcoma requires more aggressive therapies, including emergency surgery, chemotherapy, and radiation therapy.
Here are some common treatment options for hemangiosarcoma:
- Surgery: Surgical removal of the tumor is often the most effective treatment option, especially if the tumor is caught early.
- Chemotherapy: Chemotherapy may be recommended after surgery to help prevent the cancer from spreading.
- Radiation therapy: Radiation therapy may be used to treat tumors that cannot be removed surgically.
- Blood transfusions: Blood transfusions may be necessary to replace blood lost due to internal bleeding.
It's essential to work with a veterinarian to determine the best course of treatment for your dog's hemangiosarcoma. With prompt and proper treatment, some dogs can live for several months or even years after diagnosis.
Types
Sebaceous gland overgrowth or hyperplasia can be a common issue in pets, leading to skin problems.
There are several types of sebaceous gland abnormalities that can affect pets, including adenomas and epitheliomas.
A sebaceous gland adenoma is a benign tumor that can grow on the skin, causing discomfort and skin issues.
Sebaceous gland hamartomas are rare, non-cancerous growths that can also appear on the skin.
Sebaceous gland adenocarcinoma is a type of cancer that affects the sebaceous glands, requiring immediate veterinary attention.
Here are some common types of sebaceous gland issues:
- Sebaceous gland adenoma/epithelioma
- Sebaceous gland hamartoma
- Sebaceous gland adenocarcinoma
- Sebaceous gland overgrowth or hyperplasia
Sebaceous Cysts in Dogs
Sebaceous Cysts in Dogs are a common issue that can be caused by various factors, including Sebaceous gland overgrowth or hyperplasia, Sebaceous gland adenoma/epithelioma, Sebaceous gland hamartoma, and Sebaceous gland adenocarcinoma.
These cysts can appear as a raised area of skin or nodule, and their size can vary from less than ½ an inch to over 2 inches. Sometimes, you may see multiple growths.
Symptoms of Sebaceous Cysts in Dogs can be quite varied. There may be inflammation, a cyst may become infected, it may bleed, or it may ooze a yellow substance. Some cysts are slightly mobile under the skin.
If your dog has Sebaceous Cysts, it's essential to have a veterinarian check any type of growth that may appear on your dog. Pet Insurance can help cover the cost of many common pet health conditions, including the removal of Sebaceous Cysts.
If the cysts found on your dog are cancerous, the recovery and management will involve subsequent treatment with follow-up appointments to determine if the cancer is being eradicated. In some cases, the area where the cysts were located will eventually heal, but it's not uncommon for them to resurface, or for new cysts to appear.
Here are the types of Sebaceous Cysts that can affect dogs:
- Sebaceous gland overgrowth or hyperplasia
- Sebaceous gland adenoma/epithelioma
- Sebaceous gland hamartoma
- Sebaceous gland adenocarcinoma
It's crucial to keep the area clean and not bathe your dog until the veterinary caregiver gives permission. Your dog may also have to wear an Elizabethan collar to prevent him from licking or biting the area as it heals.
Stopping the Bleeding
Applying pressure is a cornerstone of stopping bleeding in dogs. A bandage is often necessary for a wound that is bleeding either heavily or persistently.
If your dog bleeds through a bandage, don't remove it! Add another layer and keep applying pressure. Dr. Nancy Reese, DVM, PhD, warns that applying too much pressure can damage the tissues.
To slow bleeding in the legs safely, apply pressure in the armpits and groin areas with your hand. This can often slow bleeding without cutting off circulation completely.

Tools to Stop Dog
You can stop dog bleeding with tools you likely have at home. A clean cloth can be used in a pinch to bandage a wound.
Some methods for stopping dog bleeding are already in your house. You can use nonstick pads and gauze, which are ideal for bandaging a wound.
Applying pressure is a cornerstone of stopping bleeding, just like in human first aid. Cover the wound with a bandage and apply direct pressure.
If your dog bleeds through a bandage, don't remove it! Add another layer and keep applying pressure.
Covering the wound with a protective bandage can help prevent bleeding if your dog has a tumor. This can be especially helpful if your dog is prone to knocking against the tumor and making it bleed.
Applying too much pressure can damage the tissues, so be careful not to press too hard. If the skin around where you are pressing is turning white, you are probably pressing too hard.

Bleeding Dog Ear
A bleeding dog ear can be quite alarming, but in many cases, it's not an emergency. There are a lot of blood vessels in the ear, so they bleed a lot.
Applying pressure to the affected area can encourage the blood to clot. Keeping your dog still and avoiding any head shaking is also crucial.
It's amazing how a tiny cut can bleed so much, often at the tip of the ear. In many cases, once you get your dog cleaned up, you may find a small cut that's easily treatable.
Medical Treatments
Researchers are investigating novel interventions to treat hemangiosarcoma, a type of cancer that can cause bleeding lumps on dogs.
Antibody therapy, which targets the protein VEGF that stimulates angiogenesis, has shown promise in inhibiting the growth of new blood vessels associated with hemangiosarcoma.
Immunotherapy, specifically liposome-encapsulated muramyl tripeptide phosphatidylethanolamine (L-MTP-PE), has been used in combination with splenectomy and systemic chemotherapy to treat hemangiosarcoma, resulting in a significant survival benefit in dogs with splenic hemangiosarcoma.
Here are some new treatments being explored:
- I'm-Yunity, a compound derived from the mushroom Coriolus versicolor, has been shown to significantly improve survival times in dogs with splenic hemangiosarcoma.
- eBAT, a new drug, has improved the 6-month survival rate to approximately 70% in dogs with splenic hemangiosarcoma, with 21% living more than 450 days.
Hemangiosarcoma Diagnosis
If your furry friend develops a skin mass larger than a pea or one that has been present for more than a month, it's essential to have it evaluated by a veterinarian.
A veterinarian should aspirate some cells from the mass to determine the type of growth, as no one can simply look at a skin mass and know what it is.
Early identification and intervention for dermal and subcutaneous forms of hemangiosarcoma are crucial, and that's why Dr. Sue Cancer Vet advocates for #WhyWaitAspirate.
Patients with visceral hemangiosarcoma often don't show any clinical signs until a tumor ruptures to cause internal bleeding.
Some blood and urine tests, as well as diagnostic imaging, will be recommended to diagnose hemangiosarcoma, including:
- Complete blood count – a non-invasive blood test that measures red blood cells, white blood cells, and platelets
- Serum biochemical profile – a non-invasive blood test that assesses liver and kidney function, as well as electrolytes (i.e.: sodium and potassium) and certain gastrointestinal enzymes.
- Urinalysis – non-invasive urine test that helps to evaluate renal function and to screen for possible urinary tract inflammation and infection.
- Coagulation profile – a non-invasive blood test helps determine if a patient can properly form a proper blood clot
- Chest radiography (x-rays) – a non-invasive imaging test to screening for evidence of heart and lung changes, including metastasis (cancer spread)
- Abdominal radiography +/- sonography – non-invasive imaging of the abdomen can assess organ size and architecture, and identify tumors of internal organs
- Echocardiography – Sonographic examination of the heart can evaluate this organ’s function, identify tumors of the heart, and confirm the presence of abnormal fluid in the sac around the heart (called pericardial effusion) caused by a bleeding tumor
A definitive diagnosis of hemangiosarcoma is made by removal and biopsy of the tumor.
Hemangiosarcoma New Treatments
Hemangiosarcoma is a serious cancer that affects the blood vessels, and unfortunately, it's often diagnosed at a late stage when the cancer has already spread. The spleen, liver, and heart are the most common sites for hemangiosarcoma inside the body.
Researchers at the University of Pennsylvania's School of Veterinary Medicine are investigating the efficacy and safety of antibody therapy to inhibit the activity of vascular endothelial growth factor or VEGF, a protein that stimulates angiogenesis, the formation of new blood vessels.

A new compound derived from the mushroom Coriolus versicolor, called I'm-Yunity, has shown promise in improving survival times in dogs with splenic hemangiosarcoma. In a recent study, dogs who received I'm-Yunity had a significantly longer survival time compared to those who only underwent surgery to remove the spleen (199 days vs. 86 days).
A team of researchers at the University of Minnesota's College of Veterinary Medicine has published exciting results on a new drug called eBAT used in dogs with splenic hemangiosarcoma. This new drug improved the 6-month survival rate to approximately 70%.
Here are some new treatments being explored for hemangiosarcoma:
- Antibody therapy to inhibit VEGF
- Immunotherapy with L-MTP-PE
- I'm-Yunity, a compound derived from the mushroom Coriolus versicolor
- eBAT, a new drug that has shown promise in improving survival rates
These new treatments offer hope for dogs with hemangiosarcoma, and further research is needed to confirm their effectiveness and safety.
Yunnan Baiyao
Yunnan Baiyao is an herbal blend from the Yunnan province in China. The exact formula is a closely guarded secret.
It can be helpful for internal bleeding, though we don't fully understand how it works. It appears to activate platelets.
This remedy can be applied topically to a bleeding area. Stopping or slowing internal bleeding is especially useful for the cancer hemangiosarcoma.
It's essential to consult with your veterinarian before starting this supplement and to keep up with monitoring bloodwork. Yunnan baiyao can elevate liver values over time.
Hemablock
Hemablock is a product that's great at stopping bleeding, and it can cover wounds up to 30 square centimeters in size. It's a great addition to your first aid kit if you like to take your dog hiking or he has a talent for getting into trouble.
You can apply the powder directly to the wound and apply gentle pressure until the bleeding stops. It's usually available in powder form, but can come in syringes for easier application.
Hemablock can even be used inside the body, and your vet might use it during surgeries. This is especially useful if your dog has a tumor on her skin that's prone to bleeding, and surgery is the best option to resolve the issue long term.
It's available for purchase through veterinary pharmacies, making it easily accessible for pet owners.
