The brownish-red color under some small dog's eyes is called Weeping Eye. It is usually on miniature poodles. It happens when a dog crys.
10 caps full of water + 1 cap full of hydrogen peroxide = solution. Put off to the side for now.
Take wet cloth and treats.
Wet your dog's eyes, gently.
Now, if you wish to cut the fur (only do this if their eyes are crusty) do so now. Be very carful!
Dip a dry cloth in solution and gently rub on the area under the eyes.
She prolly thinks she was being punished so I gave her another treat.
If your dog is cooperating, you can dry the area. But then you are done!
A bonus feature Vine! Haha! Isn't she cute?!
