HI boxers friends!! My Gus will be one year old on July 4. I am looking to start to transition from puppy food to adult food. In the past, my other boxers have had issues with food, and took a long time to figure out what worked for them. Its been a while, so I am looking for some advice on the best way to go about transitioning, and a good brand that will keep him healthy, and a smooth transition.
