Aaaaargh.......... I'm sharing DQ's computer and even though I log off and log in in my own name, for some reason, the computer gremlins appear and it reverts back to DQ when I post. This is Luella.
Did your vet shed any light on what the cause could be? In any event, colloidal silver will do nothing but help. Put some in her waterbowl and you may notice that she will be drawn to it, thereby drinking more water. Also, I would definitely add iodine supplementation. Why don't you go to the iodine forum for specific advice on how much to give Haley? I believe you will notice a difference with these two things.
