We get to pick up our gsd puppy tomorrow - got the call tonight - and the breeder is currently feeding the Sam's club puppy food. I don't want to keep feeding him this, but have been told that switching foods quickly is not a great idea. Don't really want to buy 40 lbs if I am going to switch over slowly, though. We want to put him on Avoderm or Blue Buffalo as quickly as possible, but am concerned about going from a very poorly rated food to one of these.
I Totally over-analyze things; I just don't want to mess up his tummy.
Any puppy experts with advice? TIA!
