How does he look. Thin, Normal, Fat. Can you see if there is a dog house and water bowl. As for the eyes, It could be a number of things allergies, conjuncititis, or eye entropion, It's hard to say. Just keep a watch on him esp. since it is getting warmer. If there is no water bowl. or dog house, I would call it neglect. And if no one ever plays with him or spend time with him, yes I think it would be neglect.
