I've been meaning to post this for a while, we thought it would be helpful to someone at sometime in the future. This is purely here as reference 🤓. The email is a little long so I'll also summarise as well.
We wanted to ensure our girls were in good health as they get older, so we looked at getting some natural remedies to help them along. It turns out that some types had an adverse affect on one of our Huskies, they can block the absorption of Zinc and resulted in some nasty issues. All is good now, but as mentioned above we felt this was something that needed sharing, just in case someone else came across it. On a plus note, I was very impressed with the owners of the product (large company), really went out of their way to document and collect as much information as possible to help. I've attached our original email and the first response, there is more but that not needed .
