98% of dog parents report visible coat improvement within 90 days. Most notice less scratching in the first 30 days, with continued improvement through 90 days. Dermal barrier repair is cumulative.

USP verifies that ingredients match their label claim, are free from heavy metals, and meet potency standards. AOAC validates our testing methods themselves. FCC certifies that ingredients meet food-grade purity. Together they confirm that what's on the label is exactly what's in the chew.

Most owners safely combine Tratez with other supplements and prescription medications, including steroids and prescription anti-itch medication. Always check with your vet before combining or weaning off any prescription medication.

Tratez Skin & Coat is formulated for dogs 6 months and older. We recommend consulting your veterinarian before starting any supplement for pregnant or nursing dogs, or dogs on prescription medication.

While most dogs love our chews, there are always picky ones! We recommend crushing up the chew and mixing it in food if your dog isn’t fond of them right away.
