Dogs can get many different diseases. Heartworm is the most common, and the most dangerous. Dog diseases such as heartworm worms live in the heart and pulmonary arteries of infected animals. The worms travel through the bloodstream until they reach the vessels of the heart chamber and lung. Your dog can have several hundred heartworms inside of it, and it may take up to five years for them to die. Another common disease is kennel cough, which is a group of respiratory infections that causes inflammation of the voice box. It is very similar to a human chest cold. Another virus that can cause a life-threatening illness in dogs is canine parvovirus. This virus can be spread from dog to dog by infected people and can cause a variety of illnesses.
Periodontal dog diseases and oral infections are among the most common health problems for dogs today. In fact, 70% of pets have some degree of dental disease by the time they’re two years old. Periodontal disease is the result of an accumulation of tartar and dental plaque on the gums and teeth. These dog diseases cause a variety of problems including bad breath, discolored teeth, and bone and tissue loss. Severe dental disease can lead to even more serious issues such as pathological fractures of the lower jaw bones or an oronasal fistula.
Dog skin infections may be bacterial or fungal. There are several bacterial species that can invade the skin barrier, which can increase the likelihood of these organisms taking over. These infections are often associated with inflammation, skin flaking, and generalized redness and erythema. In severe cases, your dog may even emit a pungent smell. Treatment for this condition depends on the type of infection, and your vet will determine the best treatment plan for your dog.
The symptoms of heartworm disease in dogs depend on the number and length of the parasites in the dog’s body. Heartworm disease affects the heart, so symptoms will vary from dog to dog. A dog may show only mild or moderate signs of heartworm disease, or it may experience severe signs, including chest pain, weakness, and listlessness. Chest radiographs can be helpful to determine the severity of an infection.
Infection by Leptospira occurs when a dog comes into contact with urine or abraded skin from an infected reservoir host. In addition to contact with the reservoir host, dogs can also become infected through ingestion and through broken skin and mucous membranes. Leptospira serovars can cause mild illnesses in dogs or severe ones in puppies and older dogs.
Infected dogs may cough up blood. There are several symptoms of parainfluenza. Coughing may be dry or wet and productive or inactive. Your dog may also develop fever and have a decreased appetite or show no interest in usual activities. Nasal discharge may also be present, but a cough will not be indicative of a bacterial infection. In some cases, your dog may be asymptomatic dogs may be the primary vectors of disease.
One of the most common dog diseases is Giardia, a parasite found in drinking water and in the feces of infected animals. Dogs can contract Giardia by drinking from puddles, eating infected feces, and even by digging in the litter box. People can also become infected with Giardia by licking an infected dog or stepping on its face.
While many dogs are susceptible to the symptoms of orchitis, a number of conditions can trigger the inflammation of the testicles. Among these are mumps, which is a viral infection in children, and pyrogenic orchitis, which results from an inflammatory process of the epididymis. Other conditions that can cause orchitis include infection with certain bacteria, as well as systemic granulomatous disease.
Dogs are at risk for developing cancer of different types, and melanoma is the most common type. This cancer arises from cells called melanocytes, which produce pigments that give our skin and coat its color. Although many types of dog cancer are treatable, some are incurable and spread to distant organs. Unfortunately, surgery is not always successful. Because cancer is a serious and disabling disease, early detection is vital to help minimize your dog’s risk of developing a malignant tumor.
