This is my first working line litter. I use to feed my Europ. Showline litters Solid gold until we personally had a bad experience with it. We then fed Wellness. I have heard some troubling things about them now too. The litter is 3 weeks old now so I need to get ready to start them on food soon so I was looking for some ideas. We also will be giving them puppy gold (I think that is what it is called lol) by peak performance. Thanks for your help.
