Tumors in dogs: types, symptoms and treatment

A tumor is a pathological growth of body tissues that occurs as a result of the abnormal reproduction of its cells. More often tumors are observed in adult dogs older than 7 years, there is a breed predisposition.

For example, in German shepherds, boxers, dachshunds, terriers and schnauzers, skin tumors are more common than in other breeds. Caucasian Shepherd Dogs, Great Danes, St. Bernards, Rottweilers and Newfoundlands are prone to bone tumors, and Cocker Spaniels, boxers and some terriers most often show leukemia. Most often in dogs, there is a tumor of the mammary gland, as well as lymphomas, tumors on the abdomen, paw, spleen, skin, under the tail, genitals, papillomas and lipomas.

Tumors of the mammary gland in dogs

These tumors are the most dangerous, since they are malignant in 50% of cases. They develop in adult animals and often lead to death due to metastases in the vital organs. Cocker spaniels, terriers, boxers, poodles, dachshunds, pointers and Irish setters, German and Scottish shepherd dogs are most susceptible to this disease. One of the reasons is considered long-term hormonal disorders.

Symptoms appear as soft nodules in the mammary gland, which grow and harden over time. Often this process is noted after a false mind or heat. Often tumors affect more than one gland. The main method of treatment is radical surgery, but it is effective only at the initial stage of cancer.

Papillomas in dogs (warts) are quite common, especially in the oral cavity. Often they dot the mucous membrane of the cheeks, gums, lips, tongue and throat in a huge amount. In appearance, warts sometimes resemble cauliflower and, as a rule, first appear on the lips and then spread to the throat and oral cavity.

After 1-6 months they disappear. These are benign tumors that are usually caused by the dog papillomatosis virus, which is transmitted through contact with a sick animal. Not everyone gets sick, and dogs with a weakened body. Sick dogs get resistant immunity to the disease.

Previously, the papillomas were only removed, they are now being treated with local injections of fosprenil with novocaine, injecting papillomas. Fibrosarcomas occur on the mucous membranes of the gums and cheeks. These tumors are dense in consistency, often recurrent, and may be ulcerated. Their treatment is only surgical.

Symptoms, treatment and removal of tumors in dogs

Bone tumors are more common at the age of 6-7 years in large breed dogs (divers, St. Bernards, Great Danes, etc.) and more often affect the long tubular bones of the forelimbs.

Symptoms include

  • lameness,
  • swelling and tenderness in the affected area,
  • the dog does not want to get up, especially in the morning

The outcome depends on the speed of diagnosis and the ability to cut a tumor.

Testicular tumors in males are usually detected in older dogs over 10 years old. Every fourth case is found in dogs with cryptorchidism, most often in collie, boxers, Airedale Terriers and Fox Terriers.

Symptoms are manifested by an increase and compaction of the testicle, it becomes an uneven shape, and the scrotum swells.
The uterus tumor is rarely found in dogs. It is diagnosed only by palpation, since it is more often asymptomatic. Treatment is possible only operative - ovariohysterectomy.

Tumors of internal organs are not visible at all, therefore they are diagnosed rather late. Their symptoms are quite diverse and can be in a state of the animal a variety of changes. These are respiratory problems (cough in dogs, wheezing, shortness of breath), disorders of the gastrointestinal tract (vomiting, diarrhea in dogs and constipation), metabolic disorders, changes in blood composition, neurological symptoms. According to these signs, and they can be suspected.

Tumors in dogs are benign and malignant or cancerous. Benign grows like a capsule, which separates the tumor from the surrounding tissues. Therefore, it is removed without consequences. Malignant tumors germinate, penetrating into the surrounding tissue and destroying them. They also metastasize - with the flow of lymph and blood spread throughout the body. Such tumors are not always possible to remove and the prognosis of the disease, especially with late diagnosis, when metastases are already detected, is disappointing.
