Just re-posting this from chat.
I'm looking for a last ditch solution really. My beloved dog of 18 years is fit and healthy (just about) apart from the fact that she hates bright light and in particular going from dark to bright light, which is a problem in the garden with all the shadows.
She really really cannot tolerate it now and so I'm having to think about putting her to sleep. This is breaking my heart. I don't want her to suffer though. Before I have to take that step, can I ask if anyone knows if anything can be done about this problem? I've looked at dog sunglasses online but am not sure if she would like wearing them. It feels so cruel to be making this decision when she loves her food and isn't arthritic other than a bit of stiffness and could otherwise have some very happy months left in her.
I am really distraught so anything anyone knows about this and can suggest would be great. I do know I will have to let her go eventually .
