There are so many different brands of dog food out there. I am lost on what to get the little girl when she comes home. The breeder has the pups on Eukanuba Large Breed Puppy Food. Is this a good brand to just keep her on? I've looked into the raw food and with two young kids I doubt I will be able to keep up with the defrosting and everything involved with it. Down the line as the kids get older I will have more time to go that route. I have heard Kirklands is really good? Any suggestions? And how do I switch her to another brand?
