I have a 2year old Beagle, and I can honestly say if I knew then what I know now I would never of had a Beagle.
I am an experienced Dog owner, did loads of research before I had her, but the research does not prepare you for the reality of owning a Beagle. Thay are so different to any other breed. She barks a hell of a lot. She requires hour and half walking per day. She gets stir crazy if she doesn't go out, can't miss A day no matter what.
She chews everything and anything. I have to keep her crated when I leave her, even 2 minutes to go to the loo, she will steal and destroy in that 2 minutes. I have to watch her like a hawk when she is not in crate, will steal anything, is totally obsessed with food. Steals off worktops, bins, your plate when it is in front of you!
She has stolen from people's picnic in park. jacket potato and tuna went down well, that she stole of couple eating lunch in park. She is a nightmare.
Digs up lawn, has to be chained in the garden as she escapes.
I have been taking her to dog training since she was eight weeks old, we still go every week for fun, she is very good at training, brilliant recall, fantastic off lead, Unless she's smells food. Have silver award in obedience. And the reason she is brilliant at training is because I use treats.
Honestly she is really really hard work.
I have a cavalier King Charles as well and I can't tell you how easy he is.
I have children, and I work from home most of the time. Beagle goes in day care when I am in office which is once in 3 weeks 9.30 to 3.00, but I can't leave her that long as I have to crate her.
Seriously think about the commitment a beagle will mean. Plenty of other posts on beagles if you search dog house, some from me and other owners saying the same.
