  • ✓ Four vet-formulated active ingredients, backed by science
  • ✓ Delicious bacon flavor dogs lap up over their favorite food

Products listed on third-party marketplaces are not guaranteed to be genuine and are not covered by our guarantee.

How Long Until I See Results?

Most dogs start showing their first changes in 2–3 weeks. The scratching, licking and chewing usually begin to ease first.

The bigger shift comes with daily use, as the skin barrier has time to rebuild and the coat starts looking healthier.

One pour a day, every day, is what gets you there.

Feeding Guidelines

Pour it over one meal a day. It works with dry food, wet food, fresh food or raw feeding.

Daily amount by dog size:

  • Small dogs: 1 ml daily
  • Medium dogs: 1.5–2 ml daily
  • Large dogs: 2–3 ml daily

Use consistently for best results.

Is It Safe?

Yes. The formula is designed for daily use and includes ingredients commonly used to support skin, coat and joint health in dogs.

If your dog has a medical condition, is pregnant, or is already on a treatment plan, we recommend checking with your vet before adding any supplement.

60-Day Guarantee

We stand behind every order with a 60-day guarantee.

Is this right for my dog?

It is made for dogs dealing with recurring scratching, paw licking, chewing, dry skin, dull coat or seasonal skin discomfort.

If those issues keep coming back, supporting the skin barrier from the inside can be an important part of the routine.

Any of this sound like your dog?

You are not imagining it. Skin, coat and comfort issues often show up in small daily signs before they become a bigger routine problem.

Dog scratching at night

Night scratching

The collar jingle, the back leg thumping, and the restless nights that keep coming back.

Dog licking paw

Paw licking

Constant licking, chewing, stained fur between toes, and paws that never seem to settle.

Dog skin irritation

Hot spots

Spots that calm down for a while, then return again in the same areas.

Dog belly irritation

Red belly or ears

Pink irritated skin, ear discomfort, face rubbing and coat changes that keep repeating.

It can also show up as
  • Persistent ear issues
  • Constant face rubbing
  • Chewing at the tail
  • Red or swollen paws
  • Dry flaky skin
  • Dull or thinning coat
  • Crusty patches
  • Restless sleep
  • Seasonal flare-ups

Why it keeps coming back

Many products focus on quieting the symptom. World Pet is designed to support the skin barrier and daily wellness from the inside out.

1

Collagen runs low

As dogs age, natural collagen production can decline, affecting skin, coat and connective tissue support.

2

The barrier weakens

Collagen helps support the structure that keeps skin resilient, hydrated and comfortable.

3

Discomfort repeats

When the skin barrier is stressed, licking, scratching and coat issues can become part of the daily routine.

4

Support daily

A consistent daily pour gives your dog targeted nutrients to support skin, coat and joint health.
