Dog diseases – Learn everything about prevention, symptoms, and treatments

Just like human illnesses, dog diseases are very serious. They can often be even harder to detect, since dogs cannot tell us where it hurts or what feels uncomfortable. This is why every small change in behavior can be an important signal for owners.

Dog diseases in brief:
– Many cancers and degenerative diseases are similar to those in humans.
– Infectious and genetic diseases can often be prevented with vaccination and screening.
– Behavioral changes are the earliest signs: lethargy, loss of appetite, inactivity.
– Veterinary check-ups are recommended every six months, even without symptoms.
– Early detection can save lives, as many conditions are treatable if diagnosed in time.

Why is early detection important?

Most diseases begin with mild symptoms that are easy to overlook. A dog may seem more tired, lose interest in play, or experience changes in appetite. However, these signs can often indicate serious problems such as cancer, joint disorders, or infections.

The most common dog diseases

Among the most frequent dog diseases are musculoskeletal issues (e.g. hip dysplasia, arthritis), various skin problems, allergies, cardiovascular conditions, and tumors such as osteosarcoma or lymphoma. On these subpages you will find detailed descriptions of the symptoms, treatments, and prevention methods for each disease.

What can the owner do?

It is the owner’s responsibility to notice changes in time and consult a veterinarian. Many illnesses can also be prevented with proper nutrition, regular exercise, vaccinations, and screenings. A strong immune system is the dog’s most powerful protection against diseases.

In this category we have collected the most common dog diseases, describing in detail the symptoms, treatment options, and prevention. Our goal is to help owners recognize problems early and provide all the guidance needed to keep their pets healthy.
