A kind of core of any organism – the central nervous system. From the state in which it is located, it depends on the vital activity of humans, animals.It is for this reason that any pathology of the central nervous system is deadly.
brain tumor, regardless of origin, can lead to the dog’s disability, in severe cases – death. Fortunately, compared to tumors of other organs, brain tumors are diagnosed less frequently.
The causes of the disease
brain tumors (OGM) are classified as benign or malignant. The first are slow-growing tumors with a clear localization and highly visible boundary between diseased and healthy tissue. Tumor metastasis is not given, but if left untreated, may transform into cancer.
The second type – malignant tumors. These tumors differ rapid growth, the lack of boundaries between healthy and diseased tissue, the presence of metastases. Almost always lead to death of the dog.
Primary tumors develop directly in the area of the brain where DNA mutations occur in normal cellular structures. The mutated cells begin to actively share, disrupting and displacing healthy. This leads to the formation of the OGM.
Under secondary brain tumors is understood as tumors that develop in various organs, and trapped in the brain via metastasis.
The main reasons contributing to the development OGM, include:
- brain injury;
- radiation, radioactive radiation;
- birth defects;
- parasitic, viral diseases;
- bad ecology;
- autoimmune diseases;
- exposure to chemicals, toxic substances.
Tumors can occur in absolutely any dog, but at risk of fall, as a rule, the animals after 5-7 years, in which tumors were influenced by certain negative factors.
The results of the study found that the most common brain tumors in dogs – is astrocytoma, meningioma, oligodendroglioma, glioma, ependymoma.
What breeds are more susceptible to
brain tumors, in particular glioma, the most common in dogs dolichocephalic breeds (Scottish and German Shepherds, Shelties). The representatives of the brachycephalic breeds (Boxers, Boston Terriers, Pekingese, mastiffs) are more likely than other dogs diagnosed pituitary tumor and glioma.
The main symptoms
To determine that the dog has a brain tumor, it is difficult. Pathologies have greased the clinical picture, the symptoms often resemble other diseases of the CNS, such as epilepsy .
Suspect OGM possible by the following features:
- glazed eyes;
- swinging gait (pendulum);
- uncontrollable vomiting;
- Rotation on the spot;
- tilting the head down;
- sagging lips and eyelids;
- blurred vision, nystagmus;
- impaired hearing and smell;
- increased thirst;
- frequent urination;
- labored breathing.
And changing the behavior of the dog. It becomes aggressive or too gentle, it may refuse to eat or, conversely, to absorb all the way up packages.
Unfortunately, most dogs get to the vet at the time when the tumor reaches a considerable size.
To be able to make an accurate diagnosis, the vet is necessary, in addition to a visual inspection of the animal, to hold a series of diagnostic measures.
The important point is considered to tumor differentiation from other diseases with similar symptoms (Aujeszky’s disease, distemper and so on. D.), Which carried out the relevant studies.
The physical, neurological, laboratory diagnostic methods allow to find out the aetiology, the size and location of tumors. The most complete information gives an ultrasound, stereotactic needle biopsy, computed tomography, magnetic resonance imaging.
If the doctor suspects a secondary tumor, carried out procedures to ascertain the place of cancer localization.
Methods of treatment and prognosis
You need to start treatment as early as possible. It is important to understand that the bill is not even for months, and days. Effective drug therapy does not exist, no one drug may not contribute to the resorption of the tumor. To date, the only way to slow down the development of tumors is surgical intervention, followed by chemical and radiation therapy.
When it comes to cancer, the chemotherapeutic methods give good results only in the early stages of the disease.
Radical surgery is performed under ultrasound scanner control, and gives the maximum positive result. The procedure involves complete removal of the affected tissue (a tumor), ensuring reduction of intracranial pressure and the elimination of perifocal edema.
Sometimes the location of the tumor such that it is not possible to completely remove it. In such cases held palliative surgery – partial removal of the neoplasm. The main objective of the operation – to facilitate the dog’s condition and reduce the number of cancer cells.
After surgical partial or complete tumor removal dog undergoing chemotherapy or radiotherapy. These treatments are very effective but cause serious side effects such as severe intoxication.
In order to improve the health and quality of life of the dog is assigned to symptomatic treatment, which includes the reception:
- diuretics (Mannitol) removing intracranial pressure;
- steroids, slowing the growth of certain types of tumors;
- anticonvulsants (phenobarbital, bromide) that eliminate cramps.
It is mandatory held infusion therapy, is appointed a special diet.
As for the outlook, the doctors give them very carefully. Favorable outcome depends on age and individual dog features, size and location of the tumor, the quality and timeliness of treatment.
A better chance in dogs with benign tumors. However, it so happens that in the case of remission of the operated and treated dog can live to a ripe old age, and sometimes the dog dies, not having lived a year.
That is why it is so important at the first warning signs immediately show an animal technician.
What to do at home
After surgery, the dog must be monitored by a veterinarian. Every 3-5 months, it is necessary to transport to the clinic for neurological and control tests to monitor the result of the impact of drugs and the rehabilitation of the animal.
The first time the dog will feel malaise, weakness, pain. To facilitate such states the doctor prescribes the appropriate drugs, dosage sets.
From owner required to fulfill all the veterinary requirements, ensuring your pet a good environment, good nutrition, complete rest. It is advisable to protect it from contact with other dogs and children. It is possible that physical activity limitations have to put the dog for a little while in a cage.
Brain surgery is associated with risk. Even with the complete removal of tumors there is no guarantee that after some time not come relapse.
The danger inherent in the surgical procedure, is the possible damage to blood vessels, nerve trunks, irreversible phenomena in functional areas of the body, nerve tissues.
Prevent the appearance of brain tumors is not possible, since the mechanism of development of this disease process is not completely understood. Even with the known factors can not cope not always. However, to prevent certain pathological conditions can be.
Before buying a puppy future owner it is advisable to look at his pedigree. If the ancestors recorded growths and their causes are not installed, then you may want to refrain from buying. However, this recommendation is in most cases does not work – you can not use cold calculation when choosing a future member of the family.
