Our lovely boy’s teeth weren’t too bad as he loves hooves, horns, yak etc, but I noticed slight discolouring on his molars which I didn’t want to end up a problem. That’s when I thought I’d try Fettle Kelp Seaweed Powder to see if it does what it says on the tin, with a little scepticism. Well…..it’s brilliant! I can’t believe how clean his teeth are after 3 weeks of use and I’m sure they will continue to get better as time goes on. If you’re umming and arhing over trying this product, give it a go, you won’t regret it
