Why Feeding the Right Amount Matters
One of the most common questions dog owners ask is: how much should I actually be feeding my dog? Too little and your dog misses out on essential nutrients. Too much and you risk obesity, joint problems, and a shorter, less healthy life. Getting the portion right is one of the simplest things you can do for your dog's long-term wellbeing.
The Key Factors That Determine Portion Size
There's no single answer that works for every dog. The right amount depends on:
- Body weight – heavier dogs need more calories, but not always proportionally more
- Age – puppies, adults, and seniors have very different nutritional needs
- Activity level – a working dog or highly active breed needs significantly more fuel than a relaxed indoor dog
- Food type and caloric density – a high-quality, protein-rich food like Sigmabites is more nutrient-dense, so dogs often need less volume compared to filler-heavy alternatives
Feeding Guide by Weight & Age
Use this as a starting point and adjust based on your dog's body condition — you should be able to feel (but not see) their ribs.
Puppies (up to 12 months)
Puppies need roughly 2–3x more calories per kg of body weight than adult dogs, spread across 3–4 meals a day.
| Puppy Weight | Daily Amount (approx.) |
|---|---|
| 2–5 kg | 100–200g |
| 5–10 kg | 200–350g |
| 10–20 kg | 350–550g |
| 20–35 kg | 550–800g |
Adult Dogs (1–7 years)
Most adult dogs do well with 2 meals a day. Adjust up or down based on energy levels and body condition.
| Adult Weight | Daily Amount (approx.) |
|---|---|
| 5 kg | 100–130g |
| 10 kg | 175–220g |
| 20 kg | 290–360g |
| 30 kg | 390–480g |
| 40 kg | 480–580g |
Senior Dogs (7+ years)
Older dogs are typically less active and may need 10–20% fewer calories than their adult peak. However, protein remains just as important — don't reduce it. Focus on quality over quantity.
How to Tell If You're Feeding the Right Amount
The best real-world check is the rib test: run your hands along your dog's sides. You should feel the ribs easily without pressing hard, but they shouldn't be visibly sticking out. If you can't feel them at all, your dog may be overweight. If they're very prominent, they may need more food.
Other signs to watch for:
- ✅ Healthy weight: defined waist when viewed from above, ribs felt but not seen
- ⚠️ Underweight: ribs, spine, and hip bones visible
- ⚠️ Overweight: no waist definition, difficulty feeling ribs
Why Food Quality Changes Everything
Feeding guides assume a nutritionally complete food. A high-quality dog food made with real meat and wholesome ingredients — like Sigmabites Dog Food — delivers more usable nutrition per gram. That means your dog gets what they need without overeating, and you'll often find the recommended portions are smaller than with filler-heavy alternatives.
If you're feeding Sigmabites, follow the guide on the pack as a starting point, then fine-tune based on your dog's individual response over 2–4 weeks.
Final Tips
- Weigh your dog's food rather than using cup measures — it's far more accurate
- Factor in treats: if you give treats regularly, reduce the main meal slightly
- Fresh water should always be available alongside meals
- If your dog is pregnant, nursing, or has a health condition, consult your vet for tailored advice
