I just noticed that the white bit of my dogs eye has lumped out just wondering if anyone knows what's wrong as its worrying me :(

What do you mean lumped out? Is the eye bludging out of the socket? If so, you need to go to the vet to have it fixed. Any problems with eyes that are not attended to can cause blindness in that eye.

Take the dog to the vet. Allergies or other factors could be causeing this problem. Your vet would be able to take a look at it and give you the answer you are looking for.

This could be a stye. We just had a border collie puppy that had one on his eye lid. We took him to the vet and they removed it.
