Im getting a beagle...any help? please provide sources!?

i am getting a beagle(2 months old). i have studied dog breeds for a long time, but i would like some ideas. what kind of food should i buy for the beagle? and yes, i know that chocolate, eggs, soy, etc. is not good for dogs. what brand of food? should it be natural only? what type of toys should i buy? treats? beds? any flea repellent suggestions? and what type of leash and house training pads do u prefer? please provide information and sources. thank you!
