Angels' Eyes for dogs - how long does the 30 gram bottle last?

I am considering buying Angels' Eyes for my dog's tear stains, but was unsure which bottle to buy.
For those who have used it before, based on your experience, how long does the 30 gram bottle last you? Is that enough time, or is it better to go with the 120 gram bottle?
Thanks!
Answers:
Well, I bought the 120 gm. the bottle seemd pretty small at first sight and surprisingly the powder is not white. Why could I associate that the powder had to be white..., ha, ha, anyways. It took a week to 8 days to get results on my one year old maltese. I did not realize 100% until I cut the old stained hair. Only one tea spoonful a day. My dog eats dry food I did not stirr the powder with food, I let it sit on top of the food. The bottle is almost full. Perhaps the 30 gramm is best first. I would dfinetly recommend the product. Someone told me that adding ferromycin in the dogs food gives the same results. But I heard somewhere that eventually it damaged the dogs organs. So I have my fingers crossed with angel's eyes. Good luck. Ah... The answer, It may last three months easily

I use Eye Envy. I don't like the idea of giving my baby something they ingest. You never know what it is doing to their organs. I would check out the question and answer section on the site I buy from. They are great people and will answer any questions quickly. It works great and has no chemicals or perservatives. It is what my Vet reccomended to me. Here are some of the information from the site
Frequently Asked Questions
Q: What causes excessive tearing and staining:
A: Staining can be caused by a variety of things:
Clogged or Shallow Tear Ducts: Studies indicate that 20-25% of small dogs and cats are born with closed of shallow tear ducts. Tears overflow because there the eyelid space is not deep enough to contain them.
Excessive Tearing: When the face hair is wet from excessive tearing, it becomes a breeding ground for bacteria and yeast infections (AKA: Red Yeast, which causes deep reddish-brown stains); Low grade bacteria infections may also cause excessive tearing.
Cutting Teeth: Cutting teeth may cause changes in the head %26 mouth structure of your pet, placing pressure on the tear ducts.
Irritation %26 Allergies: Some animals get hair or eyelashes into their eyes causing irritation. Many breeds are susceptible to allergies. Shampoos and other chemicals can also irritate their eyesSome foods cause allergic reactions; animals may also build an allergic reaction over time to a type of food.
Water: Water with high mineral levels causes staining
Food %26 Treats: Diet can play a significant role in tearing. Many commercial foods contain additives, preservatives and food coloring. This could lead to staining.
Fleas: Fleas survive in moisture, which they get from the eye or moth area. This could cause irritation and in addition red stains left behind may be from flea feces. These are just a few reasons. There are MANY more!!
Q: What is Eye Envy so different that all the other products that I've bought and don't work?
A: Eye Envy works at the true problem, a bacteria infection. Eye Envy contains a cleanser, an astringent (to dry the area) and herbal flower extract (acts as a natural antibiotic) and an antibacterial.
Eye Envy is a topical tear stain remover. Other products are often masked as palatable supplements, taking months to work and requiring your pet to ingest antibiotics (e.g. tylan, tylosin as tartrate, collidal silver).
Q: What if I've used bleach or peroxide to clean the area around the eyes?
A: Bleach/Peroxide make the hair shaft very pourous, causing the stain to set into the hair. Eye Envy will only lighten the areas previously damaged by bleach or peroxide, but all regrowth will be clean.
PLEASE do not use peroxide, bleach or woolite on your animals.
