[Cheryl Pepper Millie Sophie]

Hi Everyone,
Just curious -has anyone experienced when using ZYMOX ear cleaner the one with enzymes that the wax turns a dark color?
After using in my puppy’s Millie ears-the wax turned almost black/red, no smell nothing. Just this dark color
Is this to be expected? I don’t understand why a puppy would have so much wax build up in her ears.
thanks again all
