I just found this really excellent saline wash for wounds. I wish we would have had this when Bella had her ulceration. This is over the counter. Check it out!
It doesn't have any preservatives in it so I think it would be good for any area of ulceration. I know it can be hard to find sterile saline and it is so important to wash the wounds with sterile saline so that we don't introduce bacteria to the wounds, especially if you have well water.
I just wanted to share my great find! There is a bonus to having to go to the podiatrist! I saw this on the counter while I was waiting!
