You can't raise a puppy and leave it alone for 8 hours. You just can't. It cannot go that long without messing in its crate. If you don't want it peeing and pooping on your carpets, you have absolutely got to take it outside on a regular basis all the time for months and months until it gets the idea that it's supposed to "eliminate" outside. It's difficult enough to leave a mature dog for 8 hours in a crate - they get lonely and of course they can get destructive if left uncrated. Some dogs can do this but usually the owner works up to it. It's easier if both adults in the house work different hours so the total length of time the dog is alone is much reduced. But puppies need to be walked every 2 hours and fed several times a day. You can't leave them in a crate with most toys - they can actually choke on things. So you need to provide some form of "entertainment" that is completely safe. That's not easy.
I know that loving a dog would make you smile but it's not the dog's job. It's going to be YOUR job to train it, walk it (in all kinds of weather and at all hours of the day), teach it not to chew the toys a 3 year old leaves on the floor, and more. So, are you prepared to bundle up your 3 year old and take both the child and the dog outside together if the other adult isn't home at the moment? That means, rain or snow or dark - out you all go.
Beagles are howlers too - they can howl at the moon and they like to be outside a lot. That can be a problem in an apartment with neighbors on the other side of the wall or the hall who don't want to listen to barking. All dogs are pack animals - they become part of the family and they need the family. You have to be the "alpha dog" and establish yourself as the head of the pack, so the dog knows its place. That's even more important when you have a young child who doesn't always behave properly with a dog - kids can tease or accidentally hurt the dog, and that's never good. All in all, pet ownership is a labor-intensive job.
My husband and I are dog lovers but we never got one unless one or both of us could be at home for a good chunk of time. We got a puppy about 18 years ago and raised her until she was almost 14. We got a rescue dog (adult) a few years ago but she's just as intensive because she'd been abandoned (by someone who wasn't prepared for the realities of dog ownership) and she was very insecure. So she's been labor-intensive in a different way and for a different reason. Both dogs became full members of our family, and while we do/did crate them and leave the house, it's not for longer than 4 hours.
You also have to have a plan for vacations - what will you do with the dog? Boarding dogs is expensive and can be stressful. Lots of people do it but you have to plan for it, emotionally and financially. You need a budget for veterinary care, licensing, food, accessories & equipment and more - be absolutely sure your budget can manage that. It's more money than you think! The worst worst worst thing is to take on a dog before you're fully prepared, and then give the dog up when it doesn't work out. That's not fair to anyone, but especially to the dog because it won't understand why you gave it up. The shelters are absolutely full of dogs who are sad and lonely and stressed because they've been given up.
Please don't make an emotional decision because the puppies are cute and they make you smile. Of course they do - they are adorable and sweet. But they don't stay that way. They have to be raised to stay happy and healthy and loved and trained.
