Stop the 7-day food switch.

Forcing a new diet too fast isn't 'tough love'—it's a recipe for a sick dog and a ruined carpet. You need a slower protocol.

The 50% 'Bottleneck'

Hit the halfway mark and suddenly everything stalls? That is when your dog's gut microbiome is struggling to adapt to new enzymes.

2 / 10

It’s not just 'biscuits'

Switching from Sainsbury’s basics to high-protein grain-free? That is a massive structural change for their gut bacteria to handle.

3 / 10

The 'Reset Protocol'

Don't push through the diarrhoea. Step back to the last ratio where stools were firm. Usually, that means 75% old food.

4 / 10

Give it 48 hours

If it is just a slow adjustment, you will see a fix in two days of stepping back the ratio. If not, something else is wrong.

5 / 10

Grab the Pro-Kolin

Support the digestive tract with a UK vet-standard probiotic like Pro-Kolin or YuMOVE while you perform the reset.

6 / 10

The 24-hour reset

Watery diarrhoea? Switch to plain boiled chicken and white rice for one day. No treats, no extras, just the basics.

7 / 10

Adjustment vs Allergy

Is your dog itching or getting red paws? This is not a 'stall'—it is a sign they cannot handle that specific protein.

8 / 10

Throw out the 7-day rule

Sensitive tummies need a 21-day sliding scale. It is not a race to the bottom of the bag; it is a biological transition.

9 / 10

Forget the Pumpkin

Can't find tinned pumpkin in Tesco? Use steamed, mashed butternut squash instead to help firm up their stools naturally.

10 / 10

The 'Biology' Signal

If the stool is soft, stay at that stage for 3 extra days. Do not move forward until the output is 100% right.

This isn't a food failure.

It is a pacing problem. By slowing down to your dog's natural speed, you avoid chronic inflammation and long-term gut issues.
