I would go for it for sure!! 6 - 8 year old Beagles are very sweet. Ours are 8 years old. Our girl Sadie is very hyper and full of life still. She gets out in the back yard and hunts and gets on a scent and barks and bays and all that. Pooh Bear, our boy dog is 8 too but is much more mello. He runs when he wants to, but is mostly a couch pototoe. This 8 year old might be better for your kids unless they want a hyper dog to run and chase and by hyper with. It just depends on the dogs personality. I would not let her age stop you from taking her. I'm sure she will be a joy.
