my 8 week old puppy has a yellow discharge from her eyes and it causes her eyes to matt shut...
Hi
You need to get this puppy to a veterinarian right away as she has an infection of some sort that needs treatment.
It could be a localized infection, affecting just her eyes, or it could be a symptom of one of several contagious dog illnesses.
Only a veterinarian can give you an accurate diagnosis. Left untreated at the minimum this could cause serious eye problems including blindness, at worst she could die (if she has a more systemic infectious disease). So please get her to a vet as soon as you can.
Best of luck, hope she's doing much better soon.
