Can you bring him to live with you? I too think the dog needs a better home. Being outside in a dog box all day everyday? No wonder why he is barking. And the comment about your dad about to kill him is not very reasuring.
Who was the dog for? If it is your dad's pet he needs to take care of it...if it is yours, it should live with you so that you can take care of it EVERYday. Dogs need attention everyday not just on the weekends. They are a full time job. They make awesome family members, but thats what they should be. Not just a friend you can play with when you feel like it.
If you love dogs, but do not have the time or place to keep one of your own, maybe you could volunteer at an animal shelter. I know at PetSmart they have people there on Saturdays holding the dogs and stuff while they get adopted, and there are people of every age helping out.
