why do dogs have health problems

There are numerous reasons why dogs may have health problems. Some of them include genetics, skin conditions, ear infections, and gastrointestinal diseases. It is important to be aware of these issues so you can help your dog get healthy again.


Arthritis is a cause of many health problems in dogs. It’s a progressive disease that causes pain, stiffness and decreased mobility.

The most common type of dog arthritis is osteoarthritis. This is caused by the destruction of the cartilage, which acts as a cushion for the bone. When the cartilage wears away, the friction between the bones becomes greater, and new bone forms around the joint.

There are a variety of treatments available for canine arthritis. Most commonly, medications are administered to reduce the pain. Other treatment options include injectable medications and surgery.

A natural dietary supplement called chondroitin may help with the inflammation associated with canine arthritis. Diets that contain the proper ratio of calcium and phosphorous can also help with the condition.

Gastrointestinal disease

Dogs with gastrointestinal disease have health problems, including diarrhea, abdominal pain, and dehydration. In severe cases, dehydration can be so severe that a dog may require intravenous fluids. The severity of the illness depends on the nature and location of the problem.

Depending on the cause, a dog’s diet may need to change or a veterinarian may recommend a prescription diet. Dietary changes and prescription diets may be needed for a long period of time. A dog with gastroenteritis may receive antibiotics and rehydration therapy to control the symptoms.

Malabsorption of nutrients in the feces can occur for a number of reasons. Usually, it is a result of problems with the small intestine or exocrine pancreatic insufficiency. However, other conditions such as kidney or liver disease may cause malabsorption.

Ear infections

Dog ear infections are one of the most common health problems in canines. These are caused by many different infectious agents. They may also be a result of tumors or foreign objects in the ear canal. The best way to diagnose and treat ear infections is to visit a veterinarian.

A healthy ear is pink and has an unobtrusive odor. Infected ears are red and irritated. There may be a discharge from the ear that can range from a yellow pustular to a brown crusty substance.

If your pet is showing signs of an ear infection, you should schedule a vet visit immediately. Ear infections in dogs can cause damage to the ear canal, leading to scarring and deafness.

Skin conditions

Dog skin is an important part of a dog’s health. It helps maintain the temperature of the body, stores vitamins, and acts as a protective barrier. The skin also contains sensitive nerve endings. When problems arise, it can impact the dog’s quality of life.

There are a number of diseases that can affect a dog’s skin. Some of these include allergies, parasites, and endocrine disturbances. These conditions can cause redness and inflammation. If your pet experiences these symptoms, it’s best to seek the advice of a vet.

One of the more common skin diseases is mange. Mange is caused by parasitic mange mites. Symptoms of early mange include itching and redness. A vet can help with the treatment of mange.

Kennel cough

Kennel cough is a type of upper respiratory infection in dogs that usually lasts for about two weeks. This disease is commonly caused by bacteria and viruses. Dogs can contract the condition if they come into contact with contaminated items or surfaces.

Kennel cough can be prevented by vaccination. If your dog is attending a daycare or kennel facility, your vet may recommend getting a kennel cough vaccine. These are available in oral or intranasal forms.

Symptoms of kennel cough include dry hacking cough, wheezing, and a white, foamy discharge. In addition, your dog may experience a loss of appetite. Other signs include discharge from the eyes, retching, and lethargy.


Dogs have many inherited disorders. Some are minor flaws that affect the appearance of the dog, while others are life-threatening and require corrective surgery. Aside from the inherited diseases, dogs also suffer from breed related illness.

Geneticists have discovered that DNA plays a major role in dog diseases. Most breeds have closed gene pools, which limit genetic diversity. This may be one of the reasons for the higher prevalence of inherited diseases in purebred dogs.

A recent study compared the prevalence of common inherited diseases between purebred and mixed-breed dogs. It revealed that while the purebred dogs’ average occurrence of some diseases was statistically higher than that of the mixed-breed dogs, they were not significantly different.
