What to expect
Your first 12 weeks with Itch & Immune Care
Skin and coat are slow to change. Here is a routine to follow and things to watch, not a promise.
Weeks 1–2
Start before the season
What to do. Begin daily use ahead of the months that bother your dog most, if you can. Stir the sachet into a meal.
What to watch. Take a baseline: a photo of the coat and a simple 1–5 score for scratching and paw licking once a week.
Weeks 3–4
Build the routine
What to do. Keep going once a day. Itch & Immune Care is made to support skin comfort and a healthy coat with consistent use.
What to watch. Weekly score and coat condition. Note walks, weather and new foods.
Weeks 5–8
Stay consistent
What to do. Daily use over several weeks supports a normal response to seasonal triggers.
What to watch. Whether your weekly scores change across the season.
Weeks 9–12
Check in
What to do. Review your notes and photos with your vet.
What to watch. Constant scratching, red or sore skin, hot spots or ear problems need a vet visit. Supplements don't replace diagnosis or care.
Individual results vary. This is a nutritional supplement, not a medicine, and not a substitute for veterinary care. Ask your vet if signs persist or get worse.

Real Results
Results you can see
Border collie, paws constantly. He'd lick them red on walks. Vet said it was a normal response to environmental triggers. This didn't change him overnight, but he licks way less, and the red between his toes is actually gone.
Maltese with the worst tear stains. I've tried every wipe, every powder, every 'miracle' thing. After about three weeks on this, the staining faded noticeably. I'm not saying it's magic, but I'm not saying it isn't, either
Adopted a one-year-old staffy mix who'd been on the street. Her coat was dull, flaky, just rough. A month on this and people keep asking if I changed her food. I didn't. She just looks healthy now.
Florida summers turn my beagle into an itchy mess. The vet and I have an understanding now. Started this in July. He still scratches, but not the constant wake-me-up-at-3-a.m. kind. Both of us are sleeping.
My partner is mildly allergic to our shepherd. We weren't giving her up, we were just looking for ways to support her skin so she wouldn't carry as much dander.
After two months, partner still sneezes sometimes, but a lot less. Her coat is also noticeably softer.
My old shepherd's coat got so thin on her back end the last couple of years. I figured it was just age. Vet suggested adding something for skin and coat. Six weeks in and she's got fuzz growing back in so far so good will keep the tap on progress.
Every winter, my golden would scratch himself raw on his belly. This
year I started him on this in September and he barely scratched. His coat came in shinier than usual too.

Questions
Frequently asked questions

-
Skin and coat change slowly, so judge over several weeks of daily use, not days. Many owners start a few weeks before the seasons that bother their dog. Responses vary. If scratching is constant or skin looks red or sore, see your vet.
-
Once a day, stirred into a meal at the same time each day. Many owners start a few weeks before the seasons that bother their dog and keep going through them.
-
