    Seems to be working

    By Twirp99 on Jul 27, 2021

    I have a 14 pit mix who started to develop dark tear stains about a year ago. Honestly, I had very low expectations for this product, but figured it was worth a shot. After a couple of weeks of regular use, her running dark tear stains have cleared up almost entirely. She also loves the taste (it looks and smells a little like boxed mac and cheese powder).

    No More Smell

    By Lights on Mar 23, 2020

    My shih tzu had very smelly tears. I decided to try this and it has taken away the foul smell. I have to wipe his eyes in a very sneaky way with my hands, so it's nice not to have the smell. His fur is dark so I can't tell if staining goes away.

    Really Works

    By Daffnea on Oct 23, 2019

    I have used this product for the last 6 months on my 2 toy Australian Shepherds. Both my boys had bad staining. One is a red merle and one is a red tri. I started using this product and it cleared up within about 6 weeks. I put a scoop in their food every day and they look great. Chewy is also the cheapest place that I have found to buy it.
