After trying numerous other products (most of them chemical based) Alge-ex is the only thing that has helped our Carolina dog with her allergies. Due to poor human planning, we ran out one month, and within a couple of days she was chewing her feet. After several days back on the Alge-ex, she was itch free. *

I have a 12 y/o beagle with seasonal allergies that we've struggled with for several years. After upgrading her diet, minimizing vaccines, regularly cleaning her feet, and keeping her indoor environment as clean as possible, we decided to try Alge-Ex. Though it hasn't completely eliminated her paw-licking, I do see an improvement in her itchiness. We'll also be adding turmeric and milk thistle to our regimen! *

Our youngest pooch just turned 2. He's had severe skin issues from the very beginning of his life. As he got older his issues became seasonal allergies that caused very violent scratching that would often break his skin and result in fur-loss. Listening to him cry while scratching was heart breaking. The only thing that worked was [pharmaceutical steroid] but we just couldn't get comfortable with giving a young pup a regular dose of steroids. I thought we could give Alge-Ex a try this spring/summer when the scratching started to kick in again. We're only 3 weeks in, but can already see the difference. There is still the occasional itch/scratch but I've chalked that up to normal doggie itches. it's nothing like before. For our lil' pooch, this is working!! *

Meet Brody, my four year old altered male boxer. Brody’s happy place is lying outside in a field of grass or in his “Grammys” flower garden. As a rescue I didn’t have much history about his health but quickly realized something was wrong. He began getting small red sore under his chin, his neck, and on top of his head. These sores then became scab-like. After consulting with his veterinarian, Dr. Hillary Cook, she diagnosed him with allergies. Dr. Cook recommended trying NHV Alge-Ex. After just a few days of using Alge-Ex the spots began to disappear. Now, after about two months of continued use Brody’s allergies have completely cleared up. I highly recommend this product to anyone whose pet is struggling with environmental allergies! *

We have been using the NHV products so some time now and have seen some wonderful results. We currently have two Westies with terrible allergies. It is worse in certain seasons and they seem to be allergic to everything. NHV had suggested we try the Alge-Ex and it is working great for one of my Westies. No allergy pills needed & no more ear infections! We are still working with the other fur kid who has improved but still some issues. NHV has made some more suggestions and we will see what the New Year will bring. *
