Bring home a week of whatever the puppy has been eating. Then change over slowly.
The seven-day ratio
Days one and two, three quarters old food and one quarter new. Days three and four, half and half. Days five and six, one quarter old. Day seven, all new.
Signs to slow down
Soft stool for more than a day means you moved too fast. Go back one step for two days.
Picking the new food
Look for a growth formula that meets the AAFCO puppy profile, and for large breeds a large-breed puppy formula with controlled calcium.
