The Gastrointestinal Tract

What Causes Stomach Cancer in Dogs?
The exact causes of stomach cancer in dogs are unknown. But factors like age, lifestyle, diet, poor nutrition, genetics, etc., can pre-dispose your furbaby into developing one.
Other dog breeds, too, are more prone than the others. These breeds include Staffordshire Bull Terriers, Chow-chows, and Belgian Shepherds. Senior dogs are also more at risk.
The Many Kinds of Dog Stomach Cancer
Lymphoma. This cancer begins in your dog's blood, in the white blood cells to be exact. Though lymphomas do not commonly affect the GI tract, in rare cases these can be in the form of a stomach tumor in dogs. The estimated incidence rate is 20–100 cases per 100,000 dogs for a stomach tumor in dogs.
Adenocarcinomas. This type of stomach cancer often begins in the glandular tissue (produces digestive juices to help breakdown food) and has the tendency to spread to other body parts like the liver and the lymph nodes. One study reported a male-to-female ratio of 17:7 for adenocarcinomas. Male dogs are more prone to this type of stomach cancer than female dogs.
Leiomyosarcomas. This type of cancer is in the form of tumors and often begins in the walls of the bladder, uterus, respiratory tract, and yes, the stomach. It only occurs in 35 out of 100,000 dogs, according to the National Canine Cancer Foundation (NCCF).
Mast Cell Tumors. For the record, mast cells are actually part of your furbaby's immune system. It functions whenever the body is inflamed or reacts to allergies. These cells are present in many different body parts like the nose, skin, lungs, and the GI tract. Cancer forms when these mast cells turn abnormal and create tumors.
These tumors actually release excessive amounts of the natural chemicals histamine and heparin (naturally produced by normal mast cells) and cause an overdose in your dog's body. Mast cell tumors are not unusual in dogs, about 90 dogs for every 100,000 dogs in any year, according to East Paulding Animal Hospital.
Primary Signs of Stomach Cancer in Dogs
What are the signs of stomach cancer in dogs? Stomach cancer in dogs is silent because signs and symptoms only begin to show by the time the cancer is already in its late stages. However, if you see these symptoms of stomach cancer in dogs, they should not be ignored. Look out for these signs:
Vomiting. Vomiting can be due to a dog upset stomach and one of the first symptoms of stomach cancer in dogs that you'll take note of. Sometimes, if your dog has stomach cancer, your dog's vomiting can even include blood and because the GI tract is out of control. With stomach cancer, your dog's body will be unable to digest food properly and absorb nutrients, leading to malnutrition, weight loss, and weakness.
Extreme pain. As expected, any type of cancer unfortunately brings pain, especially if there is a tumor on dogs stomach pressing or making eating uncomfortable. You will notice how uneasy your dog will become and may exhibit constant signs of discomfort like suddenly crying and whining with dog stomach cancer. If you notice that your furbaby is in pain, take them to the vet immediately where they can check for signs of stomach cancer in dogs or other illnesses.
Recurring sores. Sores can be normal for some dogs, especially for those who have skin allergies. But recurring sores that don't seem to get better are unusual. Stomach cancer in dogs can also be about wounds that don't seem to heal at all even with treatments.
Presence of unusual lumps and swellings. Lumps can be one of the signs of stomach cancer in dogs. One of the most recognizable signs of cancer in dogs is a mass, lump, or a bump that grows under the skin, particularly in the stomach area. If you notice that your dog has a mass on their stomach, it could be a symptom of stomach cancer in dogs and should be checked by a vet.
Appetite loss. Since your dog's GI tract functioning is a total mess with the presence of a stomach tumor in dogs, it will keep on pushing along the intestines that will make your dog feel unwell. This discomfort and pain will prevent your dog from having the urge to eat anything. So, a tumor on dogs stomach can quickly lead to appetite loss. For most dogs who love food, a loss of appetite can be one of the clear signs of stomach cancer in dogs for pet parents.
Energy loss. Cancer cells make use of glucose from carbs to form lactate. So, one of the symptoms of stomach cancer in dogs is a lack of energy. Lactate is difficult to absorb by the body that's why your dog will spend additional energy trying to turn lactate into a useful form. What a dramatic waste of energy.

A new diet can help a dog upset stomach or provide additional nutrients to help your dog feel better during this time.
