Dog health refers to the overall well-being of dogs, which includes physical, mental, and emotional aspects. Regular veterinary check-ups, vaccinations, and a balanced diet are essential for maintaining a dog's health. Common health issues in dogs include obesity, dental disease, and parasites, which can be managed with proper care and attention. Exercise is also crucial for dog health, as it helps maintain a healthy weight and supports mental stimulation. Activities like walking, playing fetch, and socializing with other dogs contribute to a dog's happiness and longevity. Owners should be aware of their dog's specific needs based on breed, age, and health conditions.
