Can I get a dachshund dog?

I am in high school and plan on getting a puppy this summer but i’ll have to go back to school and stay at school 7 hours a day. My dad works so no one will be at home I really want a dog but it would have to be a small dog that’s not a chihuahua I do plan on crate training the dog and putting ramps on everything to avoid the puppy jumping and climbing so it won’t have any back problems. I also plan on putting a camera in my room and my dad works 20 minutes away from the house and my neighbor has a key to the house, she is a trusted older lady I’ve known all my life so she won’t be a problem. I really want this breed specifically but I don’t want it to suffer with no one to care for it all day. I would still have to figure out how to give the dog the right portion of food while I’m away but I’m sure it wouldn’t be a problem. If leaving this breed alone for that long is a problem even with proper training, what dogs are recommended for my situation?
