Neoplasms in dogs, that is, tumors, arise in the process of abnormal cell multiplication and pathological tissue growth.
Most often, the appearance of tumors is characteristic of dogs over the age of seven. There is a breed predisposition to the appearance of tumors. For example, neoplasms on the skin are most often found in dachshunds, boxers, German shepherds and schnauzers.
Bone tumors are more prone to Caucasian sheep dogs, mastiffs, rottweilers, divers and St. Bernards. Cocker spaniels, boxers and some terriers are most often leukemia. Neoplasms can be benign or malignant. Benign tumors in dogs grow as if in a capsule that separates them from surrounding tissues.
For malignantly, germination in surrounding tissues and their destruction is characteristic. Also, malignant tumors with blood and lymph flow are carried throughout the body, that is, metastasize. Dogs often meet:
- Tumors of the genital organs,
- Papillomas and lipomas.
Tumors of bones are characteristic for dogs of large breeds over the age of six. The front paws are more often affected.
Symptoms of neoplasm in dogs
The first symptoms of the disease are soreness and swelling on the paws, lameness. The dog reluctantly rises, especially in the morning. Tumors of the breast develop in the second half of the dog's life and quite often lead to death, as metastases affect vital organs .
The most common cases are:
- Cocker spaniels,
- Scottish and German Shepherds,
- Irish Setters,
Among the reasons called long-term hormonal disorders associated with an increase in the body level of estrogen. In the mammary gland, soft knots are first palpated, which eventually harden and grow. Often, this process begins after false sucking or estrus.
Later, the nearest lymph nodes increase, around the tumor ulcers appear and hair falls out. Not infrequently tumors affect several neighboring mammary glands. Aging males can develop a testicular tumor. Most often it occurs in collies, Airedale terriers, boxers and fox terriers.
With this disease the scrotum swells, and the testicle increases in size and becomes dense and uneven. Also in dogs there are tumors of the uterus and the vagina, there are papillomas and fibrosarcomas.
- The main treatment for neoplasms is radical surgical intervention. Although its effectiveness is high only in benign formations or in the initial stage of cancer.
- Chemotherapy and intra-tumoral injections with ASD-2 preparation, which promotes necrotizing the tumor tissue, are also used.
