Canine Hemangiosarcoma (HSA) is often called a “silent killer” because dogs with splenic forms of this disease usually do not show clinical signs until it is too late.
Hemangiosarcoma is an aggressive blood vessel cancer that causes tumours on the spleen, liver or heart. It can go unnoticed until the tumours rupture and cause internal bleeding. Some dogs may sporadically bleed internally, with the blood reabsorbed by the body.
A few causes of internal bleeding in dogs include rat bait poisoning, ruptured masses on the spleen, trauma, and sometimes in the case of immune-mediated disease. Internal bleeding in dogs can often be more dangerous because it occurs inside the body, and being less obvious, delays evaluation by your veterinarian.
Hemangiosarcoma most commonly occurs in the spleen, though it can originate in other organs such as the heart, liver, kidneys, skin, muscle, and bone. The cancer occurs most commonly in dogs older than 6 years of age. It is believed to arise from primitive endothelial cells that normally form blood vessels.
Pancreatic Cancer: The Silent Killer.
Golden Retriever Lifetime Study

Currently, hemangiosarcoma is the leading cause of cancer death in our cohort of 3,044 dogs.

A bleeding episode can cause weakness, lethargy, pale gums, decreased appetite and a painful abdomen. When these signs occur, it is important that a pet be examined by a veterinarian. If a tumor is bleeding very quickly, surgery may be necessary to try to remove the mass and stop the bleeding.
Even though cancers may be slow growing, they can sometimes cause sudden signs of illness.
Pale gums, unnaturally cool extremities, and signs of pain when you touch the pet`s belly can mean internal blood loss.
The German Shepherd is an amazing dog with tons of excellent qualities. They have a lifespan of 9-13 years which is average for most dogs. There are several factors that can affect how long they live. It is important to recognize these factors and hopefully extend their lives as much as possible.
High blood pressure is often called the “silent killer”

Most of the time, high blood pressure, or hypertension, has no obvious symptoms to indicate that something is wrong.

Ovarian cancer has long been called a “silent killer,” because symptoms are thought to develop only after the disease has reached an advanced stage and is largely incurable.
The Veterinary Cancer Society also reports that pesticides, herbicides, and insecticides can all increase the risk of various kinds of cancer in dogs.
These challenges are further compounded by the fact that the onset of pain in dogs with cancer can occur and escalate very gradually over a long period of time, or in some cases pain may be caused by cancer treatment rather than the cancer itself.
A terminal haemorrhage is also known as a massive bleed. It refers to bleeding that occurs at an advanced stage of cancer and that could lead to death. Bleeding can happen either internally and not be immediately obvious, or externally with a lot of blood visible.
Gastrointestinal conditions that may cause internal bleeding include gastroenteritis, ulcerative colitis, Crohn`s disease, celiac disease, inflammatory bowel disease, and irritable bowel syndrome.
Rupture can occur spontaneously, without any traumatic injury, and cause bleeding into the abdomen. Signs of internal bleeding include lethargy, weakness, collapse, decreased appetite, and a distended abdomen. If the bleeding is severe (and untreated), it can lead to death.
Hemangiosarcomas are malignant tumors derived from the cells lining blood vessels (hem = blood, angio = vessel, sarcoma = tumor). Hemangiosarcoma is a common cancer in dogs accounting for approximately 5% of cases. Since blood vessels run throughout the body, hemangiosarcomas can develop anywhere.
Persistent, non-healing wounds or sores can be a sign that your dog`s immune system isn`t functioning properly, or is busy combating another infection. Cancers can also look like non-healing sores. Loss of appetite or rapid weight loss is a sign that something isn`t right with your dog.
The true skin form looks like a rosy red or even black growth on the skin. This form is frequently associated with sun exposure and thus tends to form on non-haired or sparsely haired skin, such as on the abdomen, or on areas with white fur.
Remember, even the most minor slip and fall can result in internal bleeding, which is why it is crucial always to have a medical professional examine you following an accident. Even so, it can take days, weeks, and even months for internal bleeding to present itself.
Immune-mediated thrombocytopenia (IMT) is a condition in which the animal`s immune system attacks and destroys blood platelets. Without platelets, blood cannot clot effectively, leading to internal or external bleeding. This can cause anemia, and is dangerous in times of injury or surgery.
Stress Can Cause Tummy Trouble

“The increased activity of the nerves cause spasms of the intestines; the stress hormones can direct blood away from the intestines; this causes diarrhea and/or vomiting-sometimes immediately, but it can occur up to 48 hours after the stressful event.”

Dogs can bleed to death within a few hours if the bleeding continues unchecked. They can be quite literally felled in their tracks. The bleeding is internal, and there is no evidence of bleeding that can be seen externally by the pet owner.

Relevant Questions and Answers :

the most relevant questions and answers related to your specific issue

Q. My 8 yo German Shepherdpassed away last night suddenly.(No noticeable symptoms) Blood was found in chest and stomach cavities. Cancer or poison?
ANSWER : A. It could have been rat poisoning ( to confirm that toxicological tests should be done). also other toxins and some trauma are possible.

Q. Which common foods are poisonous to pets?
ANSWER : A. That’s a great question. As responsible pet owners we need to be aware of food items that can be harmful to our canine or feline companions. Here are some of the most common foods proven to cause illness in our animals at home:

Chocolate: A favorite and irresistible treat amongst most humans, chocolate is considered toxic to dogs. In very small amounts it is usually not a huge issue, but with larger volumes and with darker chocolates pet owners should be concerned. Chocolate contains methylxanthine theobromine, which is similar to caffeine. Chocolate ingestion can cause vomiting, diarrhea, hyperactivity, issues with normal heartbeats, seizures, and in some severe cases, death. It is best to keep your favorite chocolate treats in a good hiding spot and out of reach of your dog or cat.

Grapes and raisins: Dogs should not consume grapes and raisins because of the risk of acute kidney failure. Most dogs experiencing grape or raisin toxicity will begin to have vomiting and/or diarrhea within 6-12 hours of ingestion. Other abnormal clinical signs include lethargy, abdominal pain, dehydration, and tremors. Kidney failure develops within 24-72 hours of the initial ingestion. There are some dogs that do not experience these devastating side effects. It is best to contact your veterinarian or veterinary emergency facility if you believe your pet has ingested grapes or raisins.

Garlic and onions: We often forget that our meals contain these two popular ingredients and will allow our furry companions a few bites or licks. Onion and garlic both can cause a type of poisoning that results in damage to red blood cells, making them more likely to rupture. They can also cause stomach upset and mouth irritation. Look for pale gums, increased breathing or drooling or any vomiting or diarrhea.

Bread dough: Unbaked bread dough is considered poisonous to our pets. The bread dough, when ingested, expands in the stomach because of the warm and moist environment. This can lead to a bloated or even twisted stomach. In addition yeast is often added to our baking products to help get bread to rise, and when this yeast is fermented it produces both carbon dioxide and alcohol. The alcohol produced can be absorbed into the bloodstream and causes dangerous drops in blood sugar, blood pressure and body temperature. Common clinical signs include vomiting or retching, distension of the stomach, weakness and collapse.

Macadamia nuts: Ingestion of these nuts are not proven to be fatal in dogs but can cause them to experience uncomfortable clinical sings, including fever, joint stiffness, vomiting, tremors and difficulty walking, especially in their hind legs. Often your pet will start to feel better after about 48 hours, but supportive veterinary care (such as pain medication) may help ease their discomfort.

Xylitol: The most common ingredient used in sugar-free gum is xylitol, which is a non-caloric sweetener. It is also found in some oral rinses, toothpastes and vitamins. Xylitol and dogs do not mix – it can cause a dangerous drop in blood sugars levels. Dogs will often display signs of disorientation, black tarry stool, tremors and seizures. If severe enough some dogs have developed liver failure. Keep your gum away from your canine companion.

Avocados: Avocados are not actually poisonous to dogs or cats but as many veterinarians can tell you the avocado pits can cause a foreign body obstruction. Avocados contain persin, which is actually toxic to the majority of pet birds. The abnormal clinical signs associated with avocado ingestion in birds include, respiratory distress, inability to perch, liver and kidney failure and sudden death.

Go forth and enjoy your favorite foods, but keep in mind which foods you should avoid sharing with your furry family members. Whenever in doubt, contact your veterinarian for healthy and safe food suggestions.

Q. Has not eaten in 2 days. Noticed a little blood on the fur on her butt. What can I do?
ANSWER : A. Blood near the rear can be caused by a number of things. Bright red blood in the stool or around the anus can indicate a problem with the colon or anal region such as constipation, tears, illness or problems with the anal glands.

Blood that is dark or black in the stool can indicate a problem with the upper intestines such as the stomach or small intestine. This is usually considered more serious than bright red stool, however any blood seen is cause for concern. If the blood is seen more than once or twice, making a vet appointment is a must.

If your dog is not eating and is having blood in either her stool or vomit, making an appointment with your local vet is best. Illness, digestive upset or problems with internal organs can all cause these symptoms. In the mean time, a bland diet of plain boiled chicken and plain white rice may help to soothe minor digestive upset until you can get into the vet.

Q. My 12 year old Border Collie/healer mix has a baseball size hematoma under her chest. I am wondering if she would survive the surgery.
ANSWER : A. My first question (if you could answer me back) would be how does anyone know it’s a hematoma, and not a hemangiosarcoma or a hemangioma? Hematomas usually resolve (eventually) on their own – they’re essentially bruises. So they don’t need to be surgically removed, typically. It could also be a hemangioma, which is a benign growth arising from a blood vessel. Typically no one can tell on cytology alone (that’s a needle sample taken from the mass and examined under a microscope) whether a growth like this is cancerous (hemangiosarcoma, or HSA) or benign (hemangioma, or HA). If a biopsy has been done and a diagnosis of HSA has been made, or it’s a HA and it’s causing your dog pain or discomfort, then I would agree that surgery is necessary.

As to whether she would survive the surgery, if your vet is competent in anesthesia (preoperative blood work and chest x-rays have been done to ensure that your dog is healthy otherwise, anesthetic monitoring on blood pressure, heart rate, EKG, oxygenation, etc will be done) and the mass is in a spot that is amenable to removal (i.e. There is plenty of skin in the area to close over the defect created by the excision) then I would say her chances of survival are very good. All this is assuming that the mass is subcutaneous (under the skin) and not actually inside the chest. If it’s in the chest, that’s a much more serious procedure. You can select “consult” if you want to talk about this further.

Q. My cavachon threw up red blood tonight, it also smelled like blood, he was coughing last night and pacing tonight until he vomited blood very red
ANSWER : A. This is very concerning. Vomiting frank blood means something within the stomach or esophagus is causing bleeding which could indicate an ulcer or injury. Have him seen by a veterinarian right away.

Q. My cats ate a small amount of chives, how worried shoul I be?
ANSWER : A. Chives are toxic to cats. Please call your veterinarian as soon as possible or the pet poison helpline:

24/7 Animal Poison Control Center

855-764-7661

Onions, garlic, chives, and leeks are of the Allium family, and are poisonous to both dogs and cats. Onion and garlic poisoning results in oxidative damage to the red blood cells (making the red blood cells more likely to rupture) and gastroenteritis (e.g., nausea, oral irritation, drooling, abdominal pain, vomiting, diarrhea). Other clinical signs of anemia may be seen, and include lethargy, pale gums, an elevated heart rate, an increased respiratory rate, weakness, exercise intolerance, and collapse. Onion and garlic poisoning may have a delayed onset, and clinical signs may not be apparent for several days.

Q. Hi my dog breast is swollen what i do
ANSWER : A. If your pet is not spayed or was spayed after 1-2 years of age there is a chance that this swelling could be mammary cancer. Mammary cancer in pets is common and the chances of cancer are decreased an the risk of getting cancer is only 0.5% if spayed before the 1st heat cycle, 8% if spayed before the 2nd heat cycle, 26% if spayed by the 3rd heat cycle. After the 3rd heat cycle spaying a pet will not decreased chances of mammary cancer.
I would highly advise that you take your pet tot he vet to have this area examined. Typically mammary cancer lumps are firm and can be on multiple breasts.
Without seeing the lump myself, another possibility here is a lipoma (soft fatty tumor) or an abscess.

Q. Cat is over 13 years old, blood test show anemia, weight loss, increase appetite, thick nails, very vocal, blood test did not show thyroid disease,tre
ANSWER : A. It is possible another metabolic issue could be causing the anemia and weight loss, or a more in-depth thyroid test is needed beyond the basic panel. Anemia can be caused by a number of things including blood loss from internal or external bleeding, failure to produce enough blood cells, or destruction of the blood cells by the immune system. Looking for causes of anemia may help you to find the underlying cause causing your cat’s symptoms. Additional tests such as ultrasound, further blood work and more may be beneficial.
