Border Collie feeding chart: portions by age and weight

Daily portion guide (adult)

These are the WSAVA Global Nutrition Committee’s calorie ranges for an average healthy adult dog in ideal body condition. They are starting points, not a prescription.

WSAVA gives these ranges for guidance only: dogs are individuals, and some need more or fewer calories to stay at an ideal, trim body condition. To turn calories into cups or grams, use the calories per cup or per 100 g printed on your food’s label: daily calories divided by calories per cup gives cups a day. The feeding guide on that label and your vet set the real amount, and your vet adjusts it by body condition: the WSAVA Global Nutrition Guidelines call for a feeding plan tailored to the individual dog.

Split into 2 meals. Energy needs drop after spaying or neutering (AAHA nutrition guidelines), so ask your vet how much to cut back.

Puppy (8 weeks to 12 months)

Standard or large-breed puppy formula (depending on adult-weight projection). Meals taper with age: 4 a day until 3 to 4 months old, 3 a day until 6 months, then 2 (Merck Veterinary Manual; Blue Cross). Switch to adult food at about 15 months, when the skeleton has finished growing, once your vet confirms growth is finished (AAHA’s 2021 nutrition guidelines: a growth diet until skeletal maturity, about 1 year for small and medium-size dogs and closer to 15 to 16 months for some larger breeds).

Senior (from about 10 years)

Senior age here is the last 25% of expected lifespan (AAHA 2019 Canine Life Stage Guidelines), counted from the breed’s median life expectancy in McMillan et al. 2024 (Scientific Reports). Older dogs do not automatically need less food or a senior formula: AAHA notes that energy needs may fall with age, but not consistently. Ask your vet to check weight, muscle and calories. Mental enrichment more important than ever. Border Collies struggle with reduced activity, so puzzle feeders and slow-feeders extend mealtime engagement.

What makes feeding a Border Collie different

Match calories to actual activity. A working sheepdog needs far more energy than a pet Border Collie doing two walks and a fetch session. Same dog, vastly different fueling.

Lean muscle bias. Quality protein matters. The WSAVA guide to selecting a pet food suggests asking the maker about nutritionists, quality control and feeding trials, instead of judging by the ingredient list.

MDR1 sensitivity. Some Border Collies (and other Collie-related breeds) carry the MDR1 mutation, which can cause severe reactions to some common drugs, according to Washington State University. Not directly nutrition-related, but tell your vet before any drug or supplement. A genetic test is available.

Mental fueling matters. Boredom is harder for Border Collies than under-exercise. Spread feeding into puzzles, slow-feeders, and training sessions to use food as enrichment.

Common breed concerns and feeding

• Hip dysplasia: lean weight + appropriate puppy formula.
• Food allergies: skin / ear / paw flare-ups → vet conversation about elimination.
• Collie eye anomaly: structural; not nutrition-related.
• MDR1: drug sensitivity; ask vet before supplements.

Sample daily routine

Active pet Border Collie, 45 lb (20 kg):

• 6:30am: breakfast (slow feeder)
• 7 to 8am: 45-min run / fetch
• 12pm: 10-min training session (treats counted)
• 4pm: 30-min walk + 10-min puzzle work
• 6pm: dinner (food puzzle)

What to keep track of

• Activity level vs portion (this is the breed where mismatch shows up fastest).
• Weight monthly.
• Skin / ear / paw flare-ups (allergy tells).
• Mental enrichment time (Border Collies do worse with reduced engagement than reduced food).
