- Go gradually. Over about 7 days, mix a little more Bully Max into the old food each day until the bowl is all Bully Max. Because 30/20 is denser (535 calories a cup), feed by calories, not by the old scoop: a 50 lb dog needs about 2.1 cups a day.

- Hill’s Science Diet Large Breed, the Hill’s formula on the Bully Max brand comparison, at 363 calories a cup and listed as a plant-based diet. Bully Max 30/20 Chicken is 535 calories a cup and meat-based.
- Is Bully Max suitable for large breeds?
- Yes. Every Bully Max dog food is suitable for large-breed dogs, including large-breed puppies, under AAFCO guidelines. Feed by calories: a 50 lb dog needs about 2.1 cups of 30/20 Chicken a day; bigger dogs, more.
- What is the Nutrient Density Rating?
- Bully Max’s own 1–10 scale, based on calories per cup and whether a formula’s protein is meat-based. Plant-protein and lower-calorie formulas score lower. It is not an independent or third-party rating. Method.
