1. Zesty Paws Allergy & Immune Bites Soft Chews

These little chews pack a serious punch against allergies.
The secret sauce?
A blend of prebiotics, probiotics, and immune-boosting ingredients like colostrum and EpiCor.
If you want to go from constant paw-licking to barely scratching within a couple weeks, then stick to a name-brand allergy relief for dogs. Plus, these salmon-flavored supplements will have your dog drooling for "treat time" every day.
All this relief doesn't come free, though. In fact, they're not the cheapest option.
But compared to constant vet visits, it's a bargain.
Key ingredients:

- Colostrum
- Apple cider vinegar
- Salmon oil
- Probiotics
Pros β
- Fast-acting relief
- Tasty salmon flavor dogs love
- Supports overall immune health
Cons π«

Some owners report that it takes a bit longer to see results compared to the Zesty Paws—about 3–4 weeks. But once they kicked in, their dog's itching decreased dramatically.
As a bonus, the skin-loving ingredient will make your pup's coat noticeably shinier too.
Key ingredients:

And that angry, painful skin? Less red and irritated.
The downside? They're pretty pricey, especially for larger dogs who need a higher dose.

The soft chews also have a mild scent that doesn't seem to bother picky pets.
