I want to say get the tests run at least a couple times after you make the changes, whether you just add a supplement, go to a different commercial diet or start with homemade. Especially since you've got something specific and measureable you're aiming at.
And, BTW, I use a Brita filter jug. Might not be as good as distilled, but it works for us.
What we do for our pets...about food
Thank you, LM
I will look into the Brita...goodness forbid I run out of water with 3 dogs... no, they would get tap water in that case. Winnie will be tested on a regular basis now, my Vet and I both know that. I have no idea why she wasn't tested after the first stone..I would like to think it was an oversight...I know that can happen. Thank you for your help!
