Gratz & welcome! It is going to depend on your new Bully's reactions to whatever you feed him/her. I think Fromm is a good start, others may have their opinions, but whatever you choose, take time to slowly transition food. I had to transition her off of the breeder's food (Canidae). I did a 10 day transition for Arwen, and had zero issues with her stool becoming soft/liquid, or her frequency of going.
I know others with more EB experience will chime in - again, welcome! oh, and... We love so make sure you have fresh batteries for your camera!
