I have a cross breed dog he's 5 years old. About half a year ago his left eye started to be runny and I used teabags to cure it. It could occasionally get worse or better but it's been still runny. Recently we noticed his eye began to be covering with a dim blue veil. We are broke and cannot take him to a vet so I was hoping if anyone could give some tips. Many thanks in advance.
We can give a tip but we cannot give your dog a cure. A blue tinge on the eye can indicate glaucoma which is a very painful condition and can result in blindness. Your dog needs veterinary help, the sooner the better.
Yes, sorry to say this but it sounds like something nasty. You need to see a vet as soon as possible.
