THE FORMULA
How it works
When your dog's immune system reacts to a foreign substance like pollen or dander, it produces antibodies that cause the inflammation behind the itching, watery eyes, and runny nose. We can't stop the allergic response, but we can support the inflammatory response causing the symptoms, and that's exactly what WINPRO Allergy does.
The plasma, spray-dried from Midwest-sourced porcine plasma, is rich in the antibodies that go after that inflammation at the source. Bromelain, nettle root, and quercetin round out the formula and support healthy skin and a healthy coat.

When will you see results?
Most dogs show changes faster than you'd expect. But plasma keeps building with daily use, so the longer you stay consistent, the better your dog feels.
Most dogs show changes faster than you'd expect — and plasma keeps building with every dose.
Weeks 1–2
Plasma goes to work. Most dogs take the soft chews right away, even picky ones.
Weeks 3–4
Many owners notice less itching, scratching, and biting at the skin.
Weeks 5–6
Irritated skin starts to settle and the coat begins to look healthier.
Weeks 7–8
Consistent daily use helps maintain healthy skin, coat, and a normal inflammatory response.
Results and timelines vary by dog. Check in regularly with your vet to track progress.
How to Feed
How many soft chews a day?
It comes down to your dog's weight. Feed it in the morning, on its own or with food. Most dogs think it's a treat anyway, so there's no fight, and the results build the longer you stay consistent.

Plasma is a natural component of blood, rich in the proteins and antibodies a dog's body already uses to manage a healthy inflammatory response. Farmers have relied on it since the 1980s to keep their animals healthy, and it's the active ingredient that sets WINPRO apart from probiotic-based chews.
Many owners notice less itching and scratching within the first 2–4 weeks, and some sooner. Plasma keeps building with consistent daily use, so give the recommended amount each day and stick with it.
Most dogs take to WINPRO like a treat, but every dog is different. If yours turns up their nose, we'll make it right — we back every order with a 100% money-back guarantee, no return required.
A couple worth flagging. Our plasma is sourced from pork, so if your dog has a known pork allergy, this isn't the right fit. And because the formula contains quercetin, it's not recommended for dogs on blood thinners. As always, it's worth checking with your vet before starting any new supplement, including WINPRO — especially if your dog has any existing health conditions. WINPRO Allergy is NASC-certified, made in the USA, with no soy or grains.
