Beagles have an average life expectancy of 13 years, according to Beaglepro.com. Their lifespan depends on their genetic history, health issues and how they are cared for. A daily walk can keep beagles healthy and exercised properly.
A good way to keep a beagle healthy for a long lifespan is to give them exercise and have them maintain a healthy weight. Getting a beagle spayed or neutered cuts down on the risk of cancer. Never smoke around beagles, as this can give them lung cancer from second-hand smoke. Table scraps are another beagle no-no. Healthy snacks can be added to the diet.
