Two complete puppy foods, two different formulations
Chudleys Puppy Junior 12kg and Dr. John Puppy Chicken 10kg are both complete dry foods designed for growing puppies. They share a similar purpose but differ in protein and fat levels, ingredient focus, and the range of life stages they explicitly cover. This comparison uses only the supplied product information so you can see what each food offers and where the details stop.
Chudleys Puppy Junior is positioned for puppies from 2–3 weeks old through to adulthood, and it is also suitable for pregnant and lactating bitches when appetite is reduced or a large litter demands extra nutritional support. Dr. John Puppy Chicken is described as a complete and balanced diet for working and sporting puppies, suitable from weaning upwards. Neither product record includes feeding amounts or a transition schedule, so you will need to follow the pack or ask your vet for a feeding plan.
Protein and fat: the clearest numerical difference
- Dr. John Puppy Chicken 10kg: Dr. John Puppy Chicken 10kg contains 27% protein and 15% fat. These figures give you a concrete starting point for comparing energy density and protein content with other puppy foods.
Dr. John Puppy Chicken 10kg - Chudleys Puppy Junior 12kg: Chudleys Puppy Junior 12kg is described as having moderate energy levels to encourage healthy and steady growth rates. If you prefer a food that explicitly targets moderate energy rather than a specific fat percentage, this is the relevant claim—but the record does not state a fat or protein percentage.

Ingredient and formulation differences
Chudleys Puppy Junior is wheat-gluten and soya free and includes a nutrient profile to support neural development and learning, with omega 3 fatty acids called out for that purpose. It also lists prebiotics for gut health and immune system development, a natural antioxidant and herb package, and nutrients to support skin and coat condition, bones, joints, and musculoskeletal development.
Dr. John Puppy Chicken highlights high levels of chicken, wholegrains for energy, prebiotics, omega 3s, and selected antioxidants. It contains no added artificial colours, flavours or sugars as standard. The record does not state whether it is wheat-gluten or soya free, so if those exclusions matter to you, Chudleys is the one with that information confirmed.
Life-stage coverage and special feeding situations
- Chudleys Puppy Junior 12kg: Chudleys Puppy Junior is appropriate for all breed sizes of working dog and is ideal from 2–3 weeks old right through to adulthood; it is also suitable for pregnant and lactating bitches. This makes it a single-food option for a breeding household or for a puppy that will stay on the same diet until adulthood, without needing a separate product for the dam.
- Dr. John Puppy Chicken 10kg: Dr. John Puppy Chicken 10kg is described as perfect for working and sporting puppies from weaning upwards. It clearly targets the post-weaning growth period for active puppies, but the record does not mention use for pregnant or lactating bitches.

What the product information does not tell you
Neither record provides feeding amounts, a recommended daily ration, or a transition plan for switching foods. You will need to use the guidance on the pack or ask your vet, especially for large-breed puppies where growth rate matters. The records also do not give calorie content, calcium or phosphorus levels, or a full ingredient list, so you cannot compare those finer points from this information alone.
If you need a food with a stated protein and fat percentage, Dr. John Puppy Chicken gives you those numbers. If you need confirmation of wheat-gluten and soya exclusion, Chudleys Puppy Junior provides that. For anything else—such as exact kibble size or specific feeding amounts—check the packaging or contact the manufacturer before relying on it.
How to choose between them
Choose Chudleys Puppy Junior 12kg if you want a food that covers a puppy from 2–3 weeks old right through to adulthood, is suitable for all breed sizes of working dog, and may also be fed to pregnant or lactating bitches. It is also the option to pick if avoiding wheat gluten and soya is a priority, or if you prefer a formulation that explicitly targets moderate energy for steady growth.
Choose Dr. John Puppy Chicken 10kg if you are feeding a working or sporting puppy from weaning onwards and want the reassurance of stated protein (27%) and fat (15%) levels, a chicken-based recipe, and no added artificial colours, flavours or sugars. It may suit households that want a straightforward complete diet for active puppies without the extended life-stage coverage of the Chudleys product.
Both are complete foods, so the decision comes down to which formulation and life-stage coverage matches your puppy and your household. If your puppy has specific dietary sensitivities or you are unsure about switching, speak to your vet before making a change.
