Collie puppy feeding chart
A Collie grows to about 75 lb (the standard's range is 60–75 lb). Puppy calories track the puppy's current weight, not its adult weight: 11 lb of puppy under four months needs about 701 kcal a day, and the daily total keeps rising until adult weight, when the factor drops and the dog needs 1578 kcal — fewer calories than it did at 30 lb as a growing puppy (992 kcal).
- 1Under 4 months 11 lb · 701 kcal

Chart: calories and cups as the puppy grows
Weigh the puppy, find the nearest row, feed that amount split into three or four meals under four months and two or three after. Re-weigh every two weeks. Cups use 369 kcal/cup (Purina Pro Plan Complete Essentials Shredded Blend Chicken & Rice (adult dry)); puppy foods are often denser, so use the kcal/cup on your bag — the sizer accepts it.

Where the stages fall for a Collie
The 3× factor applies while the puppy is under four months, which for a Collie usually means the rows up to roughly a quarter or a third of adult weight — around 11–19 lb. Between four months and maturity the factor is 2×, covering the 30–64 lb rows. Large and giant breeds like this one keep growing well past a year, and large-breed puppy foods are formulated to slow that growth slightly for joint health; the calorie math is the same, the food choice is the vet conversation.
The peak of the chart is the surprise for most owners: at 30 lb and 2× RER the puppy eats 992 kcal, but the same dog at its full 75 lb as a neutered adult needs only 1578 kcal. Watch for the hand-off and reduce the ration rather than letting the adult food amount "catch up".
Growth to watch in a Collie
The standard puts an adult Collie at 24–26 in at the withers (22–24 in for females), so a puppy at the 41 lb row — a little over half its adult weight — is typically most of the way to full height and still filling out. Because females of the breed finish around 65 lb rather than 75 lb, a female puppy's rows stop short: read the chart to about 55 lb before switching to the adult factor. The gap between the 64 lb puppy row (1751 kcal) and the adult row (1578 kcal) is the amount to cut at the switch.
Crate divider positions
The same growth rows are a guide for the divider in the adult-size crate. A Collie ends up in a 36 in or 42 in crate — see the Collie crate size page — and the divider should give the puppy only enough room to stand, turn around and lie flat at each stage, moving back roughly every re-weigh.
