My Chihuahua has some serious tears. I clean around her eyes with a tear stain remover, rinse with water, and dry. 1 hr later and the dirt and crap is all around her eyes again. I cleaned her eyes twice daily and it kept coming back. On Sat she has an appointment with the vet for the last of her puppy shots and I will see what they say. This can't be normal tears. It's black and comes off like greasy dirt. Her ears get black crap in them as well. I cleaned her up yesterday and today the dirt is back in her ear. She's an indoor dog.
