> I am picking them up in two weeks
wooo... i would not take on two bully pups (well i wouldn't do 2 of any breed personally), but having had bullies for my whole life i would not want two developing in the house at the same time. 1 pup brings chaos and destruction. To put it in perspective my current boy once ate a wall, two together would have had the house down! They are not an 'easy' breed and need a lot of time attention without pup being more interested in its brother/sister.
With regards feeding unfortunately I have never found that the bullies do well on on premium quality food, certainly not the foods I would like to feed. However, the others are right, your breeder should provide you with a feeding schedule and product for your pup(s) and should be about to make reccommendations for adulthood based on their own dogs.
I take it this/these are your first bullies, so if you have any questions give us a shout! :)
