How much Tear Stain Powder should I give my pet?

Tear Stain Powder is dosed by your pet’s body weight.

Daily dose

Pet weight	Daily dose
Cats (all weights)	1/2 sachet
Small dogs under 20 lb	1/2 sachet
Medium dogs 20–50 lb	1 full sachet
Large dogs 50+ lb	1 full sachet

Why the dose plateaus for larger dogs

The active L-lysine and lutein doses in one full sachet are calibrated for daily porphyrin support. Going above this doesn’t speed up the process — the body absorbs what it needs and excretes the rest.

If your large-breed dog (75+ lb) has heavy tear staining and you’re not seeing change by week 6, talk to your vet rather than increasing the dose on your own.

Half-sachet handling

For cats and small dogs taking half a sachet:

1. Tear open the sachet and pour roughly half into the food bowl.
2. Fold and clip the sachet shut (or use a small zip-bag).
3. Store in the original box and use within 48 hours.

If you have a two-meal-a-day routine, splitting a sachet across both meals (quarter + quarter) is the cleanest way to avoid leftover-sachet storage.

Multi-pet households

If you have both a cat and a dog with tear-stain issues, each gets their own dose based on their own weight. Don’t share a single sachet across two pets.

Don’t change the dose mid-way

If you’re not seeing results, check consistency and topical care before adjusting the dose. Increasing the dose rarely accelerates results meaningfully — but it does increase the chance of GI adjustment side effects.
