How do I use Petterm Tear Stain Powder?

Petterm Tear Stain Powder is a daily, food-mixed supplement that works from the inside out — reducing the porphyrin compounds that cause the reddish-brown staining around the eyes.

Daily routine

1. Pick a meal — once a day, same meal each time. Most pet parents use the morning meal.
2. Tear open one sachet for the right weight class (see dosage guide).
3. Sprinkle over wet or dry food. For dry food, add a small splash of warm water or broth to help the powder cling.
4. Stir to coat. Mix lightly so the powder is distributed across the food.
5. Serve immediately.

What’s in the formula

• L-lysine — binds the amino acid building blocks of porphyrin, reducing the compound that causes staining.
• Lutein and zeaxanthin — eye-area wellness antioxidants.
• Cranberry extract — supports the natural elimination pathway for porphyrin compounds.
• Probiotic blend — gut health support, which helps the body process pigments more efficiently.

Pair with topical care for fastest results

Internal-only treatment fades new tear stains. The existing stained fur won’t disappear overnight — it has to grow out. To speed visible results, gently wipe the eye area daily with a damp soft cloth or a pet-safe eye wipe. This removes new staining before it sets.

What to expect in the first week

The powder is mild-tasting and most pets accept it without issue. Some pets have slightly looser stool for 3–5 days while the probiotic content takes hold — this is normal.

If your pet refuses the food, start at half dose for 5 days before increasing.

When to expect results

New stain reduction typically shows up by week 2–3. Visible coat fading takes longer — see When will tear stains fade? for the timeline.
