Get a starting point for dog weight management: estimate weight status and daily calories, then work with your veterinarian on a suitable plan.
Dog Weight Management
Estimate your dog’s weight status and a rough calorie target for a vet-guided weight plan.

Weight Management Plan
Position Within Healthy Range
This bar shows where your dog sits within the selected category’s typical adult weight range — not progress toward a goal. The healthy range is broad, and a dog can be healthy near either end depending on frame and muscle.
Calorie & Timeline Details
Body Condition Score Guide (7-point)
| BCS | Description | Action |
|---|---|---|
| 1 | Severely underweight | Vet visit urgently — no DIY plan |
| 2 | Underweight | Vet check before gain plan |
| 3 | Slightly underweight | Gentle gain plan |
| 4 | Ideal | Maintain |
| 5 | Slightly overweight | Gentle loss plan |
| 6 | Overweight | Structured loss plan, vet-supervised |
| 7 | Obese | Vet-supervised loss plan only |
Safety first: Never aim for more than 1–2% body weight loss per week. Rapid weight loss can cause serious health problems, especially in small dogs. Always involve your veterinarian before starting a weight loss program, and re-check every 2–4 weeks.
How It Works
Each breed-size category has a broad healthy adult weight range (see cards). This range is not breed-specific — a Labrador and a Greyhound are both “Large” but have different healthy weights.
Step 2 — Target weight
Target = middle of the healthy range for the selected category.
This is a rough heuristic. A proper target uses the dog’s body condition and frame at BCS 4–5, assessed by a veterinarian.
Step 3 — Calorie target
RER = 70 × (weight in kg)0.75
Then multiply by a factor:
· Weight loss: 0.8 × RER (initial deficit; never below RER without vet supervision)
· Maintenance: ~1.4–1.8 × RER depending on life stage (neutered adults ≈ 1.8, intact ≈ 1.6 in many references — conventions vary)
· Weight gain: ~1.8 × RER
Step 4 — Timeline
Safe loss rate: 1–2% of body weight per week
Safe gain rate: 0.5–1% of body weight per week
Timeline is a linear estimate — real weight change slows as the dog approaches target.

Why BCS matters more than the scale: Body Condition Score is a hands-on assessment of fat cover. A dog can be a healthy weight at different numbers depending on frame and muscle. BCS guides whether weight loss or gain is appropriate — the scale alone doesn’t tell the whole story. BCS is best assessed by a veterinarian.
