For Brothers, shipping is free if you order is over $40. If you transition regularly, their gut gets healthier and they no longer get upset stomachs from new foods. A lot of upset stomach issues are because the dog doesn’t have a diverse population of probiotics and probiotics are supposed to help with digestion. They can’t help if they are not there. At first, I had to do a very slow transition between foods but I kept at it and before too long I was able to do a normal transition, now mine need no transition and it doesn’t even matter to mine if I feed low fat one day and high fat the next. I have not had any upset stomachs from my dogs in well over a year now.
I do it differently in Summer because where I live is not conducive to keeping kibble fresh, high heat, high humidity.
