What is what age is a dog considered a senior?

The age at which a dog is considered a senior can vary depending on breed and size. In general, smaller breeds are considered seniors around 7-9 years old, while larger breeds are considered seniors around 5-7 years old. However, some smaller breeds can live into their mid to late teens and still be considered active and healthy seniors.

Signs that a dog is entering their senior years include a decrease in energy levels, changes in appetite, weight gain or loss, graying of the muzzle, arthritis or joint stiffness, and changes in sleep patterns. It is important for senior dogs to receive regular check-ups and screenings to monitor their health and well-being.
