The breed of dog can have a big impact on its lifespan. Smaller dogs, such as chihuahuas and poodles, tend to live longer than larger dogs, such as German shepherds.
A dog's health can also affect its lifespan. Dogs with chronic health conditions, such as heart disease or cancer, may not live as long as dogs that are healthy.
Dogs that eat a healthy diet, with plenty of fruits, vegetables, and whole grains, tend to live longer than dogs that eat a diet high in processed foods.
Dogs that get plenty of exercise are less likely to become overweight or obese, which can lead to health problems.
Vaccinations are important for protecting dogs from diseases. Dogs that are vaccinated are less likely to get sick, which can help them live longer.
Spaying or neutering can help to reduce the risk of certain types of cancer, as well as unwanted behaviors, such as aggression and roaming.
Regular checkups with your veterinarian can help to identify and treat health problems early on, which can help to extend your dog's lifespan.
