Eight-week itch-trial protocol
Use it as a structured trial: strict 7-day transition (our schedule here), zero table food, and score itching weekly. Dogs with environmental atopy improve partially; diet-responsive dogs improve clearly by week 6–8. The guaranteed omega-3 label means the dose is enforced — most competitors list fish oil without quantities.
Who needs more than SSS
Confirmed multi-protein allergies need hydrolyzed veterinary diets, not retail formulas. Dogs failing the 8-week trial should see the vet — our skin & coat file and Wellness CORE comparison map the escalation ladder. For the price, nothing else in retail matches the evidence-per-dollar.
FAQ
How long until itching improves on SSS?
Partial improvement often shows by week 3–4; a fair trial runs 8 weeks with zero off-diet food.
Does SSS contain chicken?
The salmon formula omits chicken meal, though some batches carry poultry fat — strict chicken-allergy cases should verify the current bag or choose truly limited diets.
