Can cancer be cured in dogs?

50% of dogs over 10 years old get cancer. Uncontrolled cell growth in your pet's body can begin in any organ (bones, muscles, skin, liver, or spleen).

No one knows what causes cancer, but it is known that the tendency to its development is inherited. Bad nutrition, infections, fleas, ticks in dogs, tobacco smoke, asbestos and even some vaccinations play a big role. Golden retrievers, German shepherds, poodles, boxers, rottweilers and shelties are more likely to develop cancer than other breeds.

And the least inclined to cancer are the Airedale Terriers, Dachshunds, Irish Setters, Jack Russell Terriers, Collies, and Yorkshire Terriers.

Types of cancer in dogs

Dogs have the same forms of cancer as humans. The only difference is in the rate of spread of the disease. For example, people develop high rates of cancer of the lung, stomach, and intestines, and in dogs, skin, breast, bones, and blood (leukemia) are in first place in time.

Skin cancer

This is the most common cancer in dogs. Older dogs aged over 10 years are especially prone to it. Therefore, it is important to regularly check the condition of their skin. If you notice wounds in dogs that are very difficult to heal, lethargy and unusual changes in the behavior of the dog, then you should visit the vet. Signs of skin cancer can be determined while the dog is bathing, carefully examining its head, neck and shoulders.

The development of basal tumor cells is most often susceptible to poodles and cocker spaniels. There is squamous cell skin cancer. It can appear as a result of the harmful effects of the sun and looks like warts on the stomach and near the genitals.

The easiest way to notice melanoma. In most cases, it is benign, but if pigment spots spread along the gumline or on the dog's paws, this is an alarming sign. Benign melanoma is an abnormal cells that germinate in one place and do not spread throughout the body. But they can also cause serious harm to the body.

Bladder cancer

It develops most often in dogs in those families where they smoke a lot. Its occurrence is also affected by some mite and flea shampoos, which contain ingredients made from petroleum (benzene, toluene, xylene). Scottish terrier is the most susceptible to this type of cancer. He suffers from bladder cancer 20 times more often than other breeds.

Osteosarcoma (bone cancer)

This type of cancer is most common among large dogs. For example, in dogs weighing more than 40 kg, the front legs and the upper part of the hind legs are often affected. Animals begin to limp. Recent studies show that if the dog is not neutered, the risk of bone cancer is sharply reduced.

Amputation of the limbs in osteosarcoma helps relieve pain, but does not cure cancer, which usually causes metastases in the lungs. In cats, bone cancer is rare.

Breast cancer

A small area is usually affected, but then metastasis spreads throughout the body. To reduce the risk, ovaries are removed from cats and dogs. In the case of illness, the entire breast line is usually removed.

Another common form of cancer in dogs is lymphosarcoma. Since the lymph nodes are located throughout the body, it is necessary to treat the entire body.
Occurs oral cancer. Its signs are nosebleeds, difficulty in eating and swelling along the jaw or cheeks.

Prostate cancer in dogs is a fast-growing tumor, unlike humans. This type of cancer quickly goes to the lungs, bones and lymph nodes. The owners often notice that their dog is beginning to experience difficulty defecating. The prostate gland compresses the lower part of the colon. Sometimes there is blood in the urine (hematuria).

If testicular cancer is found in a dog, then after complete removal of them by surgery, most animals recover quickly. Most of all, testicular cancer is affected by domestic dogs that have been exposed to herbicides and drugs used to kill parasites.

The main signs of cancer in dogs are:

  • abnormal swelling,
  • wounds that do not heal for a long time,
  • weight loss
  • loss of appetite
  • blood from the nose, mouth or rectum,
  • fetid odor
  • eating problems
  • loss of interest in games or walks,
  • difficulty defecation,
  • unusual limp.

Canine Cancer Treatment

In some forms of cancer, therapeutic treatment is carried out, slowing down the development of a tumor in a dog. Sometimes only surgery is indicated. All veterinarians agree that in any case it is necessary to strengthen the immune system of the animal.

1. Irradiation
X-rays can kill cancer cells in areas that are difficult to access for surgery. For example, irradiation is done only in the area of ​​the brain that is affected, not touching the surrounding cells. But radiation is not always effective, as some cells, such as melanoma, are immune to normal doses.

Radiation can lead to hair loss, discoloration of the skin and hair regrowth in unusual places. Sheepdogs and poodles especially lose their wool.

2. Chemotherapy
Chemotherapy uses highly toxic chemicals to kill cancer cells. It is important for a dog to determine the correct dose. Therefore, a veterinarian measures the surface area of ​​a dog, not its weight. Chemotherapy drugs include vincristine, vinblastine, 5-fluorouracil, and doxorubicin. For cats, many of them are not suitable, as they are fatal.

Chemotherapy can cause loss of appetite, nausea, vomiting, weakness and hair loss.

3. Cryotherapy
Freezing with liquid nitrogen is mainly used for small tumors on the skin.

4. Synthetic retinoids
These are vitamin compounds (eg, acitretin). They are used to treat precancerous conditions in dogs. Often used fish oil, in which a high content of vitamins A and D.

Good work of the immune system increases the likelihood that natural killer cells will destroy small cancer cells. To do this, herbs, vitamins, minerals, medicinal mushrooms, selenium, turmeric and homeopathic preparations (Hepar, Carcinosum and Lymphomyosat) are introduced into the dog's diet.

Carbohydrates should be excluded from the diet - this increases the life expectancy of animals with cancer. Studies have shown that wheat, corn and sugar contribute to the growth of cancer cells, therefore it is better to introduce fish, broccoli and linseed oil into the pet's diet. Veterinarians recommend feeding the animal often and in small heated portions to stimulate the sense of smell.

If you notice any warning signs, take the dog to the vet. Visiting the veterinarian twice a year increases the likelihood of a cure for cancer, since in the early stages it is most easily treatable, as in humans.
