What are beagles used for today?

This could be a long list... Some of the uses are; hunting, transportation, guiding, guarding, companionship, and drug and bomb detection.

They also do service work for the disabled (ie service dogs), visit hospitals to cheer patients (therapy dogs), water rescue, tracking, protection, acting, modeling, search and rescue (like 9/11), and carrying things.

Some dogs are trained to detect natural gas leaks, rot in utility poles, cadavers, or cancer
