Hi all 1 of my girls in 1of her eyes is very dark pink the other 1 is normal, sometimes her eye go's back to normal i think she maybe going blind. What do you all think. I am going to take her to the vets but just wanted to know what you all thought is was.

This is the sort of thing which cannot be diagnosed over the net, and requires a qualified person to examine the dog. It's possible she has an eye infection which can be easily treated, so make a vet's appointment as soon as possible.
