Canine diseases refer to various health issues that can affect dogs, ranging from infections to genetic disorders. Common diseases include canine parvovirus, which is highly contagious and can be fatal, and canine distemper, a viral illness that affects the respiratory and nervous systems. Regular veterinary check-ups and vaccinations are essential for prevention. Other notable conditions include hip dysplasia, a genetic disorder affecting the hip joint, and canine diabetes, which occurs when a dog's body cannot properly regulate blood sugar levels. Early detection and treatment are crucial for managing these diseases and ensuring a dog's well-being.
