Overview
PENPEN's dog allergy chews are peanut butter flavored soft chews combining probiotics and omega-3 fish oil, aimed at supporting itchy skin and immune and gut health, sold as a 180-count bag.
The formula pairs a gut-health ingredient, probiotics, with a skin-support ingredient, omega-3 fish oil, rather than relying on a single active ingredient, an approach suited to chronic itch that may stem from either digestive or skin-barrier causes. As a supplement rather than a medication, it is meant for ongoing support rather than fast relief of a flare-up.
- 180 soft chews per bag
- Probiotics and omega-3 fish oil
- Peanut butter flavor
- For itchy skin and gut support
Who it's for
Fits owners managing a dog's recurring itchy skin who want an ongoing soft chew supplement rather than a topical treatment. Not a fit if a dog needs immediate relief for a severe allergic reaction, since this is a daily supplement, not a fast-acting medication.

Performance notes
