90-Day Reported TimelineWhat changes,
What changes,
and when.
Week 1
Calmer digestion
Softer transitions between meals, more consistent stools, settled gut.
Week 3
Visible coat shift
Fur sits flatter, more reflective. Owners notice before vets do.
Week 6
Mobility unlocked
Stairs, jumps, post-walk recovery — all faster. Joint stiffness fades.
Week 12
A different dog
Sustained energy, immune resilience, the version of your dog you remembered.
