The 7-day rule is a myth. If they have 'soft-serve' stools on day four, you need to change tactics now.
Brands suggest a week, but your dog's gut microbiome isn't reading the label. It needs time to recalibrate enzymes, not just change flavours.
Most transitions stall halfway. This is the tipping point where new ingredients overwhelm the old bacteria. Gas and bloating start here.
Know the difference. Minor softness is a sign to slow down. Liquid diarrhoea or mucus means the transition has officially stalled.
Stop all kibble for 24-48 hours. Your dog's gut needs a total break from the inflammation to heal before you try again.
Forget just rice. Use boiled white fish (cod or whiting) from the local fishmonger with plain mashed spuds. No butter, no salt.
When 7 days fail, try 21. Start with just 10% new food. It sounds slow, but it's the gold standard for sensitive Irish setters and terriers.
If the stool softens at any stage, don't push through. Drop back to the previous ratio for 3 days until things firm up again.
Check the label for 'poultry fat' or 'fish meal' if your pup has known allergies. Even 'Lamb-based' foods can contain hidden chicken.
Add a boost like Pro-Kolin or YuMOVE. These introduce good bacteria directly to bridge the gap while the gut recalibrates.
Vomiting or lethargy? Get to a vet in Dublin, Cork, or Galway immediately. Dehydration in puppies happens much faster than you think.
Most 'intolerances' are just rushed timelines. By respecting the 21-day biological clock, you turn a messy transition into long-term gut health.
