Quick Bowl Check: Powdery white stool means excess bone — trim RMB by 2%. Loose dark stool usually means too much liver or sudden fat; step organs in slowly over 10 days.

How Do You Calculate Raw Meaty Bones for a 10% Bone Ratio?

Divide your dog's daily pure bone gram target by the cut's bone percentage, then subtract the extra meat attached to that bone from your boneless muscle portion. For a 500 g daily bowl needing 50 g of pure bone, feeding skin-on chicken necks (36% bone) takes 139 g of whole chicken necks and reduces boneless meat by 89 g.

Common Questions From Dog Owners

Should I calculate raw dog food from current weight or ideal weight?

Always plug in your dog's ideal adult weight for grown dogs. If your Labrador weighs 38 kg on the vet scale but should sit closer to 31 kg with a visible waist tuck, feed 2% of 31 kg (620 g daily). Only growing puppies are calculated from their current weekly weight.

Does heart count as muscle meat or secreting organ in 80/10/10?

Beef, chicken, turkey, and pork hearts count as boneless muscle meat — never as part of your 10% secreting organ quota. Because heart is rich in taurine and purines, cap it at 10% to 15% of total muscle meat so it doesn't trigger loose dark stool.

Can I feed kibble in the morning and raw food at dinner?

Yes. Despite old forum myths about stomach pH conflicts, healthy dogs digest mixed feeding without trouble; millions of households feed dry kibble at breakfast and a raw meal at night. Just split each daily total in half so you don't double-feed calories.

Why did my dog's poop turn white and crumbly on a raw diet?

Chalky, dry white stool is classic 'bone poop' — a clear sign your bowl carries more than 10% pure calcium bone. Cuts like duck frames and skinless chicken necks are roughly 75% bone, so fold in extra boneless thigh or beef trim at the very next meal.
