Like any hound, they're bound to roam if you let them off the leash around a house in the country. That's a silly excuse to not adopt them. We have a beagle from a local rescue and a bassett/beagle mix from BROOD that are never off leash simply because they will hunt. That's why many beagle/hound rescues require fenced yards. But they are amazing pets and friends.
As for hunters, these dogs sit in cages for the majority of the year, and do what they are born to do when asked. Not all hunters treat the dogs the same, but unfortunately the majority of them have their favorites and the rest are cast off. We recently found a malnourished stray beagle sick with tumors around almost all her nipples because she was not fixed, and the dog came to us wagging her tail. Amazing, loyal, resilient animals. I hope to be more involved in rescuing soon, but with a four-month old baby girl and two hounds, the house is full right now.
I'd love to have more info on the Bagels & Beagles thing, when you have the info.
