It’s the missing ingredient in some dog foods, but at a much lower cost to add to regular food than purchasing the expensive foods. It’s easy to sprinkle on top of my dog’s food to boost the nutrition.

The results from this are seen almost right away. After only a few days of use the dog’s teeth looked soooo much cleaner. I even told my vet about it and they said they’ve heard of a few patients using the supplement and it being very effective. I have a very picky heeler and he doesn’t mind this supplement in his food at all! Worth the money for sure.

We have 3 Golden Retrievers and use this on a regular basis. I do believe it helps with digestion, metabolism, skin/coat and several other things. They are all in excellent condition and their health is very good according to their vet.

We love the back40 sea kelp supplement. For being a street rescue, my dog is pretty picky. So I wasn't sure he was going to like it. He loves it and if I forget to put it in his food I will definitely notice it when he hasn't touched it. So naturally we put in another order when we began to run low. The "sealed for your protection" cover was opened and the cap was loose. There was loose sea kelp in the box. Amazon won't take the return and I'm not sure I want to use it since the seal is broken. Other than that I do love their products.

So i decided to do a little experiment and stopped using all of the back 40 suplements I use and then restarted about a month later. Wanted to see if there was a noticable differences. Well it pretty much blew me away. I intitally started the Kelp because my dogs have very bad breath and twice now ive noticed the bad breath goes away after 2-3 days of use. In the long term my vet went from telling us "we might need to schedule a cleaning soon" to "they dont need one yet we can definatley put it off a while". Added bonus its stinky and the dogs love it. Genuinley an all rounder great for them and they seem to like it.
