I pick up my puppy Sept 12th. And have a few questions. I know the breeder currently has Newman on Royal canin and I was going to go with that until reading on here and other sites. I've decided to go with either taste of the wild high prairie with bison and roasted venison puppy, or blue buffalo wilderness grain free, thoughts? Last question the crate I have on hand is 24" long , 20" inches wide and 21" high is this big enough just to start him out I'm? I really appreciate any input. Thank you
