A:

I can only speak from the experience of 30 years’ breeding gundogs and being associated with them in the shooting and trial world.

In all that time I cannot recall a springer with two blue eyes, all being brown, varying in depth from very light to dark hazel, the colour required by the breed standard and desired by many trainers.

I would be surprised if your puppy’s eyes now change colour from blue.

As this colouration is so unusual, I would advise you to have the puppy’s eyes checked by a specialist to make sure there are no other unusual differences that could affect her eyesight, or, if she is bred from, any offspring.
