Help with giant breed puppy food?

[Humphrey_hamster]

Hi everyone, it's been a while since I've posted anything and this one (clearly) isn't about hamsters. My parents and I recently adopted a 3/4 Newfoundland 1/4 Saint Bernard pup (6 months next week) we've only had him for a week and a bit. He came to us on Beta large breed puppy. We would prefer him on a different food. Any suggestions? I will keep you updated on not only his foods but also what's going on. We took him to his first puppy class on the Tuesday just gone I hope to post a couple of pictures of him soon
Thank you
