Puppy Nutrition Guide for Border Collies
A growth-diet brief for medium-breed Border Collie (30-55 lb adult, typical lifespan 12-15 years) puppies - calorie density, calcium limits, and feeding frequency that protect MDR1 testing and high exercise needs.
Clinical context
Why this stage is different for Border Collies
Border Collie puppies should finish growth looking athletic, not “well covered.” Adult weight lands around 30-55 lb; overshooting in the first six months is how MDR1 testing and high exercise needs shows up years early. Medium breeds tolerate twice-daily meals once teething settles; weigh every two weeks. Growth typically closes near 12-14 months for this size class. Keep a weekly weight chart in the same vault as stool quality and vaccine dates.

Feeding timeline through growth close
8-12 wk
Transition from breeder diet
Change foods over 7 days. Log stool score daily so a protein or fat jump is obvious.
3-6 mo
Peak growth calories
Expect rapid gain. Recalculate portions every 2 weeks for this Border Collie.
6-9 mo
Slow the curve
If the waist disappears, cut 10% calories before adding joint supplements as a “fix.”
12-14 months
Adult food decision
Move to adult maintenance when the veterinarian confirms growth-plate timing for this size.
12 mo+
Audit the pantry
Drop puppy-density food. Archive the brand/lot that agreed with this dog for future elimination trials.

Vault protocol for diet changes
- Photograph the bag (guaranteed analysis + lot) whenever you change formulas.
- Record body-condition score beside weight - Border Collie coats can hide a rib layer.
- Note fish-oil, probiotic, and chew calories; they are not free.
- Keep a one-line log if stools or itch flare - relevant to MDR1 testing and high exercise needs.
- Share the feeding timeline before boarding so staff do not “be kind” with extra cups.
Bowl notes
What “best food” means for this breed
A calorie-dense small-breed puppy kibble or a complete fresh plan both work if portions are weighed.
Home cooking is not “healthier” unless a veterinary nutritionist balances it - growth diets are easy to get wrong.
Watch MDR1 testing and high exercise needs: diet is one lever, not a cure. Pair feeding notes with the clinical briefs linked below.

Three to four meals until about six months, then two. Toy and small Border Collies are hypoglycemia-prone if a meal is skipped. Weigh portions; cup-scoops drift.
Around 12-14 months for this size class, or when your veterinarian says growth plates and body condition support adult calories. Giant breeds stay on controlled-growth diets longer than toys.
