Forcing a new diet too fast causes 'metabolic chaos.' Here is why your pet's gut can't keep up.
Your pet's gut microbiome is a complex ecosystem. When you swap proteins, you're asking billions of bacteria to reorganize instantly. They need more than a week.
This is the danger zone. Half old, half new. If you see soft stools here, your pet has hit their threshold of tolerance. Stop adding more new food immediately.
Loose stools for over 48 hours? That is a stall. Pushing to 75% now won't help the gut 'catch up'—it will likely cause a full digestive shutdown.
Don't quit. Just step back. Return to the last successful ratio (usually 75% old food) until the stool firms up for two full days. Let the gut heal.
Forget 25% jumps. Move by only 10% every three days. It takes longer, but it is much faster than treating an emergency bout of gastroenteritis.
Is the new food more nutrient-dense? If it's richer, the same volume is too much for the small intestine to process. Check the calories, not just the cups.
Plain canned pumpkin (not pie filling!) absorbs excess water and feeds good bacteria. One tablespoon can save a stalled transition and firm things up.
Start probiotics three days BEFORE you switch. It’s like sending a scout team to prepare the microbiome for the new ingredients arriving soon.
If stools never firm up despite a slow switch, it isn't a transition problem. It's an ingredient incompatibility. Look for chicken or beef triggers.
Vomiting twice or seeing blood? That is not a 'transition' anymore. That is an emergency. Stop the switch immediately and seek professional help.

A successful diet change is measured in gut stability, not calendar days. Respect your pet's unique microbiome, and they will thrive on their new fuel.
