Learn how to feed your senior medium or large breed dog with Calibra Verve GF Senior. Get portion guidelines, transition tips, and key nutrition facts for a grain-free diet.
Quick answer
Feed Calibra Verve GF Senior Medium & Large to dogs 6+ years weighing 10–90 kg. Start with the lower end of the feeding chart and adjust based on your dog's activity and body condition.
Why a grain-free senior formula matters
Senior dogs often have slower digestion and may benefit from a diet higher in animal protein and lower in carbohydrates. The 65/35 animal-to-plant ratio in this food provides concentrated protein from chicken and duck, which helps maintain muscle mass as your dog ages.
The added prebiotics (MOS, FOS, β-glucans) support gut health, while Mojave yucca can reduce stool odor. These features are especially useful for older dogs with sensitive stomachs or owners who want less smelly cleanups.
Portion guidelines: start low, adjust slowly
Every dog is different, so the feeding chart is a starting point. For a 10 kg dog, begin with about 100–120 g per day. For a 40 kg dog, start around 250–280 g. For a 90 kg dog, you may need up to 450 g daily.
Split the daily amount into two meals to aid digestion and prevent bloat, especially in deep-chested large breeds. Monitor your dog's weight every two weeks and adjust portions by 10–15 g increments if needed.
Transitioning from another food
Switch gradually over 7–10 days to avoid digestive upset. Mix 25% new food with 75% old food for days 1–3, then 50/50 for days 4–6, then 75/25 for days 7–9, and finally 100% new food on day 10.
If your dog has a very sensitive stomach, extend the transition to 14 days. Watch for loose stools or gas, and slow down if needed.
Feeding decision rules
- Daily portion starting point: For a 10 kg dog: 100–120 g/day. For 40 kg: 250–280 g/day. For 90 kg: up to 450 g/day. Divide into two meals.
- Transition schedule: 7–10 days: 25% new / 75% old (days 1–3), 50/50 (days 4–6), 75/25 (days 7–9), 100% new (day 10). Extend to 14 days for sensitive stomachs. Slow transition reduces risk of loose stools and gas.
- When to adjust portions: Check body condition every 2 weeks. If ribs are hard to feel, reduce by 10–15 g. If ribs are very prominent, increase by 10–15 g. Always provide fresh water. Portion adjustments should be small and gradual to avoid over- or under-feeding.
