  1. Distemper

Distemper is a highly contagious disease due to a human measles-like virus. The treatment consists of the administration of antibiotics and liquids to avoid dehydration . The vaccination of your dog will protect almost 100%

  1. Canine hepatitis

It is a highly contagious disease caused by adenovirus type I. The virus is released in body secretions. The acute cases should be hospitalized for intensive treatment. The vaccination is very effective in preventing this disease.

  1. Leptospirosis

A disease caused by a bacteria called spirochete that spreads through urine. The bacteria enters the dog’s body through a skin wound or by coming in contact with infected urine . Most infections are mild . In case of seriousness, the dog must be hospitalized. The disease is treated with antibiotics , mainly penicillin and streptomycin.

  1. Parvovirus

Parvovirus is a highly contagious viral disease . The virus attacks cells that are reproducing, such as those in the intestinal tract, and spreads through the stool . The disease requires veterinary attention. The accination prevents most cases of infection .

  1. Rage

Rabies is a deadly disease that occurs in most warm-blooded animals. The main focus of infection is the bite of an infected animal . The vaccine is highly effective , so we recommend you vaccinate your dog against this dangerous disease. You can see everything related to its prevention, symptoms, phases and action in our post about rabies in dogs .

  1. Brucellosis

Caused by the Brucella Canis bacteria, it causes sterility and miscarriage in dogs. It is a difficult disease to eradicate. In 80% of cases, it is eliminated by administration of antibiotics .

  1. Canine Borreliosis or Lyme Disease

Disease caused by the spirochete bacteria Borrelia Burgdorferi . It is a disease transmitted through the bite of an infected tick . A blood test will test if your dog suffers from the disease. Treatment consists of the administration of antibiotics . Anti- tick collars are highly effective against these parasites . It is also convenient to check your dog’s hair to see if it has a tick and be able to remove it.

  1. Infectious tracheobronchitis or kennel cough

Dogs can suffer from highly contagious respiratory diseases. Kennel cough is caused by various viruses and bacteria, generally the canine parainfluenza virus and the Bordetella Bronchiseptic bacteria . The most characteristic symptom is a dry , rough , unproductive cough . It is usually a mild disease that heals on its own . In some cases, it can be complicated by pneumonia or bronchitis. Find out in depth everything about kennel cough in this article .

  1. Coronavirus

It is generally a mild but highly contagious disease . Coronavirus is transmitted by contact with infected oral and faecal secretions . Treatment consists of avoiding dehydration and controlling vomiting and diarrhea. Antibiotics are generally not administered , since it is a minor disease.

  1. Toxoplasmosis

Toxoplasmosis is caused by a protozoan called Toxoplasma Gondii. Most infected dogs have no symptoms . To diagnose the disease, it is necessary to do a serology. Treatment of acute toxoplasmosis involves the administration of antibiotics.

  1. Otitis

It is an infection of the ear canal that occurs frequently in long-eared and fallen breeds . Otitis is painful. The treatment involves cleaning and drying of the ear canal and should perform veterinarian. In some cases, antibiotics or antifungals are administered. If the otitis is severe, it may require surgical intervention .

  1. Conjunctivitis

It is an inflammation of the connective membrane and is a very common problem in dogs. The most frequent symptoms are eye redness, often accompanied by secretions . In mild cases, it can be treated at home by administering an eye drop . However, it is advisable to consult the veterinarian in case you need any more intensive treatment.

  1. Skin allergies

Currently, many dogs have allergic symptoms of some kind . Generally, the symptoms that a dog presents when the allergy is triggered are cutaneous . Consult your vet, who will examine the dog and administer an antihistamine if necessary.

  1. Acute gastritis (acute vomiting)

Acute gastritis is an inflammation of the stomach wall that results in severe and continuous vomiting . It usually goes away on its own in 24-48 hours. If vomiting persists , vomits blood or foreign substances, or has diarrhea, see your vet .

  1. Diarrhea

Diarrhea is the deposition of liquid stools or reports , generally in large volumes and with an increase in the usual number of secretions. It is usually due to changes in diet or the presence of intestinal parasites. Depending on its duration, it can be acute or chronic . Chronic diarrhea requires veterinary attention, as it may be due to the presence of parasites, fungi, bacteria or syndromes of poor digestion and malabsorption.

If the diarrhea does not cause dehydration, it can be treated at home, by fasting to rest the intestinal tract and administering fluids to keep the dog hydrated . Consult your vet if you have any questions.

  1. Leishmaniosis

Leishmaniasis is a serious, even fatal , parasitic disease caused by a protozoan. This disease is transmitted through the bite of a mosquito called Phlebotomus.

If the dog does not receive treatment, the disease can be fatal , so if you think that it may suffer from the disease, you should immediately go to your vet. Leishmaniosis can be treated but not cured , since the parasite remains in the dog’s body and symptoms will recur periodically.

The disease can be prevented by vaccination . If your dog is well immunized, even if it is infected with the parasite, it will be able to live with it without causing major complications. Mosquito repellent deworming collars are also an effective method of prevention.

  1. Demodectic mange

Caused by a mite, which almost all dogs contract from their mothers in the first days of life. In a reduced number, they are considered habitual fauna of the skin . The problem is when their number gets out of control due to a failure of the dog’s immune system. You should go to your vet, who will administer the appropriate treatment.

  1. Mastitis

Mastitis can be of two types: galactostasis or breast hardening and acute septic mastitis. The galactostasis , or hardening of the mammary glands, occurs when the accumulation of milk during pregnancy and lactation is increased to the point that the breasts dilate, increase temperature and symptoms of pain.

The acute septic mastitis is an infection or abscess of one or more mammary glands, caused by bacteria. It must be treated by a veterinarian.

  1. Torsion / Dilation (Gastric Volvulus)

Gastric torsion is an emergency with fatal consequences, which can be fatal for your dog .

First, gastric dilation occurs, in which the stomach is distended with gas and liquid. Next, the volvulus is produced, which consists of torsion, that is, the stomach rotates on its longitudinal axis, displacing the pylorus from its position .

It is very important that you go to your vet so that he can remedy the situation. Surgery is often necessary .

  1. Cancer

Cancer is a condition in which rapid cell division occurs. The cells reproduce at an excessive rate and can metastasize to other areas of the body , even causing the death of the dog.

The effectiveness of treatments depends on early diagnosis. See your vet to carry out the most appropriate treatment for your dog. Most cancers are detectable by physical examination , so an annual physical examination can help prevent them effectively.
